Description

Technical Field

[0001] The present application relates to the field of optical communication technology, and in particular to a communication light detector. Background Art

[0002] Communication failures caused by the connection and disconnection of the optical fiber communication system will seriously affect the user experience. In order to reduce the connection and disconnection problems, the data center will monitor the network status in real time using network monitoring tools to detect and solve connection problems in a timely manner, ensuring that users are provided with stable and reliable optical fiber communication services.

[0003] The existing monitoring schemes all use contact detectors to perform one-to-one detection on the optical fiber to be tested in the data center cabinet to determine whether there is a continuity problem. This detection scheme uses the cooperation of the male end and the female end. Each plugging and unplugging will cause wear on the optical fiber end face. Frequent plugging and unplugging will shorten the service life, resulting in the need to replace damaged connectors and increase maintenance costs. At the same time, if it is necessary to detect the continuity of a certain section of optical fiber in the cabinet, one-to-one detection of one end of the optical fiber will result in low work efficiency. Summary of the invention

[0004] In view of this, the present application provides a communication light detector to solve the technical problems of short service life and low detection efficiency in contact docking.

The communication optical detector includes a first collimator, a second collimator, a detection optical cable and a fixing seat. The two ends of the detection optical cable are respectively connected to the first collimator and the second collimator. The fixing seat is provided with a first channel and a second channel. The first collimator extends into one end of the first channel, and the other end of the first channel is configured for the signal sending end of the optical cable to be tested to extend therein. The first channel has a first extension length so that there is a spacing between the first collimator and the signal sending end. The second collimator extends into one end of the second channel, and the other end of the second channel is configured for the signal receiving end of the optical cable to be tested to extend therein. The second channel has a second extension length so that there is a spacing between the second collimator and the signal receiving end. The inner walls of the first channel and the second channel can both reflect light.

[0006] In the above embodiment, the two ends of the detection optical cable are connected to the first collimator and the second collimator, the fixing seat provides the first channel and the second channel, the first collimator and the signal sending end of the optical cable to be tested extend into the first channel from the two ends of the first channel respectively with a spacing between them, the second collimator and the signal receiving end of the optical cable to be tested extend into the second channel from the two ends of the second channel respectively with a spacing between them, so that the two ends of the detection optical cable and the two end faces of the optical cable to be tested are non-contact docking, reducing the wear on the end face of the optical cable to be tested and the end face of the detection optical cable, and extending the service life. In addition, collimators are provided at both ends of the detection optical cable, so that the communication optical signal received by the first collimator passes through the detection optical cable and then is transmitted through the second collimator; in actual operation, a communication optical detector can simultaneously perform non-contact docking on both ends of a certain section of optical fiber in the cabinet, thereby detecting the on-off status of the section of optical fiber, and improving the detection efficiency.

[0007] In some embodiments of the present application, both the first channel and the second channel extend along a straight line.

[0008] In the above embodiment, the first channel and the second channel both extend in a straight line, which can improve the transmission efficiency and transmission quality of the communication light, reduce the signal attenuation of the communication light, and also simplify the difficulty of processing and installation.

[0009] In some embodiments of the present application, the communication optical detector further includes a first sleeve and a second sleeve. The first sleeve is provided in the first channel, and the second sleeve is provided in the second channel. Along the extension direction of the first channel, at least a portion of the first collimator extends into one end of the first sleeve, and the other end of the first sleeve is configured to allow the signal transmitting end of the optical cable to be tested to extend therein. Along the extension direction of the second channel, at least a portion of the second collimator extends into one end of the second sleeve, and the other end of the second sleeve is configured to allow the signal receiving end of the optical cable to be tested to extend therein.

[0010] In the above embodiment, a first sleeve is provided in the first channel, and a second sleeve is provided in the second channel, so that the first collimator is aligned with the signal transmitting end as much as possible, and the second collimator is aligned with the signal receiving end as much as possible, thereby reducing signal loss.

[0011] In some embodiments of the present application, the fixing seat is provided with a first stopper and a second stopper. Along the extension direction of the first channel, the first stopper and the second stopper are arranged at intervals and are configured to stop at the two ends of the first sleeve respectively. The fixing seat is provided with a third stopper and a fourth stopper. Along the extension direction of the second channel, the third stopper and the fourth stopper are arranged at intervals and are configured to stop at the two ends of the second sleeve respectively.

[0012] In the above embodiment, the first stopper and the second stopper prevent the first sleeve from falling out of the first channel, and the third stopper and the fourth stopper prevent the second sleeve from falling out of the second channel, so as to avoid the first sleeve and the second sleeve being pulled out of the fixing seat when the optical cable to be tested is pulled out of the first channel and the second channel after the test is completed.

[0013] In some embodiments of the present application, a first notch is provided on the side wall of the first sleeve. The first notch penetrates the first sleeve along the axis extension direction of the first sleeve. The first sleeve is configured to be able to produce elastic deformation to reduce the caliber through the first notch. A second notch is provided on the side wall of the second sleeve. The second notch penetrates the second sleeve along the axis extension direction of the second sleeve. The second sleeve is configured to be able to produce elastic deformation to reduce the caliber through the second notch.

[0014] In the above embodiment, a first notch is provided on the side wall of the first sleeve, and a second notch is provided on the side wall of the second sleeve, so that the cross-sections of the first sleeve and the second sleeve are incomplete ring-shaped, and both the first sleeve and the second sleeve can produce elastic deformation. When the first sleeve and the second sleeve are respectively placed into the first channel and the second channel, the caliber can be reduced, which is convenient for installation and can also avoid damage to the first sleeve and the second sleeve; after being placed in place, the inner wall of the first channel will constrain the first sleeve, so that the outer peripheral wall of the first sleeve fits with the inner wall of the first channel, and the inner wall of the second channel will constrain the second sleeve, so that the outer peripheral wall of the second sleeve fits with the inner wall of the second channel.

[0015] In some embodiments of the present application, along the extension direction of the first channel, the fixing seat protrusion is provided with a first connecting portion. The first channel runs through the first connecting portion, and the second stop portion is located in the first connecting portion. A third notch is provided on the side wall of the first connecting portion. The third notch is configured to allow an external structure to extend into the first channel to extrude the first sleeve. Along the extension direction of the second channel, the fixing seat protrusion is provided with a second connecting portion. The second channel runs through the second connecting portion, and the fourth stop portion is located in the second connecting portion. A fourth notch is provided on the side wall of the second connecting portion. The fourth notch is configured to allow an external structure to extend into the second channel to extrude the second sleeve.

[0016] Since the first stopper and the second stopper are provided in the first channel to prevent the first sleeve from slipping out, and the third stopper and the fourth stopper are provided in the second channel to prevent the second sleeve from slipping out, in the above embodiment, the first connecting part and the second connecting part are provided on one side of the fixing seat, and the third notch is provided on the side wall of the first connecting part, and the fourth notch is provided on the side wall of the second connecting part; thus, the first sleeve and the second sleeve can be conveniently taken out for replacement through the third notch and the fourth notch.

[0017] In some embodiments of the present application, the fixing seat is provided with a fixing portion. The fixing portion is provided with a first fixing hole and a second fixing hole. The first fixing hole is communicated with the first channel. The first collimator extends into the first channel through the first fixing hole, and the first collimator abuts against the inner wall of the first fixing hole. The second fixing hole is communicated with the second channel. The second collimator extends into the second channel through the second fixing hole, and the second collimator abuts against the inner wall of the second fixing hole.

[0018] In the above embodiment, by providing the first fixing hole and the second fixing hole in the fixing part, the first collimator abuts against the inner wall of the first fixing hole, and the second fixing hole abuts against the inner wall of the second fixing hole, thereby ensuring that the positions of the first collimator and the second collimator in the fixing seat are fixed, thereby reducing the possibility of the first collimator and the second collimator becoming loose relative to the fixing seat during the use of the communication light detector.

[0019] In some embodiments of the present application, the fixing seat is provided with a first stop wall. Along the direction from the first fixing hole to the first channel, the first collimator abuts against the first stop wall to restrict the length of the first collimator extending into the first channel portion. The fixing seat is provided with a second stop wall. Along the direction from the second fixing hole to the second channel, the second collimator abuts against the second stop wall to restrict the length of the second collimator extending into the second channel portion.

[0020] In the above embodiment, since a part of the first collimator is located in the first channel and another part is located in the first fixing hole, the same is true for the second collimator; the first stop wall is used to constrain the length of the first collimator in the first channel, and the second stop wall is used to constrain the length of the second collimator in the second channel, ensuring non-contact docking between the first collimator and the second collimator and the optical cable to be tested. At the same time, the first stop wall and the second stop wall are also easy to install, ensuring the position accuracy of the first collimator and the second collimator.

[0021] In some embodiments of the present application, the detection optical cable is connected to the same side of the fixing seat. A plurality of guide portions are provided on a side of the fixing seat away from the detection optical cable. The plurality of guide portions enclose a guide channel. The guide channel is connected to the first channel and the second channel. The guide channel covers an end of the first channel for the signal transmitting end to extend therein. The guide channel covers an end of the second channel for the signal receiving end to extend therein.

[0022] In the above embodiment, a plurality of guide portions are enclosed to form a guide channel, and the plurality of guide portions can cover the portion of the optical cable to be tested that is connected to the fixing seat to provide protection. The guide channel can provide guidance for the signal sending end and the signal receiving end of the optical cable to be tested to extend into the first channel and the second channel.

[0023] In some embodiments of the present application, the communication optical detector further comprises a protective cover which is detachably connected to the fixing seat and covers the detection optical cable.

[0024] In the above embodiment, a protective cover is detachably connected to one side of the fixing seat close to the detection optical cable, and the protective cover can provide protection for the optical cable to be tested, reduce damage to the optical cable to be tested caused by external impact, extend the service life, and also play a role in waterproofing and dustproofing.

The second channel has a second extension length so that there is a spacing between the second collimator and the signal receiving end. The inner walls of the first channel and the second channel can both reflect light.

[0033] The two ends of the detection optical cable are connected to the first collimator and the second collimator, the fixing seat provides the first channel and the second channel, the first collimator and the signal sending end of the optical cable to be tested extend into the first channel from the two ends of the first channel respectively with a spacing between them, the second collimator and the signal receiving end of the optical cable to be tested extend into the second channel from the two ends of the second channel respectively with a spacing between them, so that the two ends of the detection optical cable and the two end faces of the optical cable to be tested are non-contact docking, reducing the wear on the end face of the optical cable to be tested and the end face of the detection optical cable, and extending the service life. Both ends of the detection optical cable are provided with collimators, so that the communication optical signal received by the first collimator passes through the detection optical cable and then passes through the second collimator; in actual work, a communication optical detector can simultaneously perform non-contact docking on the two ends of a certain section of optical fiber in the cabinet, thereby detecting the on-off status of the section of optical fiber, and improving the detection efficiency.

[0034] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] See also Figure 1 and Figure 5 One embodiment of the present application provides a communication optical detector 100 for detecting the signal on / off of an optical cable 5 to be tested. The communication optical detector 100 includes a first collimator 1, a second collimator 2, a detection optical cable 3 and a fixing seat 4. The two ends of the detection optical cable 3 are respectively connected to the first collimator 1 and the second collimator 2. The fixing seat 4 is provided with a first channel 401 and a second channel 402. The first collimator 1 extends into one end of the first channel 401, and the other end of the first channel 401 is configured to allow a signal transmitting end 501 of the optical cable 5 to be tested to extend therein. The first channel 401 has a first extension length so that there is a spacing between the first collimator 1 and the signal transmitting end 501. The second collimator 2 extends into one end of the second channel 402, and the other end of the second channel 402 is configured to allow a signal receiving end 502 of the optical cable 5 to be tested to extend therein. The second channel 402 has a second extension length so that there is a spacing between the second collimator 2 and the signal receiving end 502. The inner walls of the first channel 401 and the second channel 402 can both reflect light.

[0036] The two ends of the detection optical cable 3 are connected to the first collimator 1 and the second collimator 2, and the fixing seat 4 provides the first channel 401 and the second channel 402. The first collimator 1 and the signal sending end 501 of the optical cable 5 to be tested extend into the first channel 401 from the two ends of the first channel 401 respectively, and there is a spacing between the two. The second collimator 2 and the signal receiving end 502 of the optical cable 5 to be tested extend into the second channel 402 from the two ends of the second channel 402 respectively, and there is a spacing between the two. In this way, the two ends of the detection optical cable 3 and the two end faces of the optical cable 5 to be tested are non-contact docking, which reduces the wear on the end faces of the optical cable 5 to be tested and the end faces of the detection optical cable 3, and prolongs the service life. In addition, collimators are provided at both ends of the detection optical cable 3, so that the communication optical signal received by the first collimator 1 passes through the detection optical cable 3 and then passes through the second collimator 2; in actual work, a communication optical detector 100 can be used to simultaneously perform non-contact docking on the two ends of a certain section of optical fiber in the cabinet, thereby detecting the on-off status of the section of optical fiber and improving the detection efficiency.

[0037] In some embodiments, the first collimator 1 may be the part with the collimating lens extending into the first channel 401 , or the first collimator 1 may be completely extended into the first channel 401 . It only needs to ensure that there is a distance between the first collimator 1 and the signal sending end 501 in the first channel 401 .

[0038] In some embodiments, the second collimator 2 may be a portion having a collimating lens extending into the second channel 402 , or the second collimator 2 may be entirely extended into the second channel 402 , as long as there is a spacing between the second collimator 2 and the signal receiving end 502 in the second channel 402 .

[0039] Although the first collimator 1 is connected to the signal transmitting end 501 of the optical cable 5 to be tested, and the second collimator 2 is connected to the signal receiving end 502 of the optical cable 5 to be tested, the first collimator 1 and the second collimator 2 may be different or may be different. The first collimator 1, the detection optical cable 3 and the second collimator 2 of the present application are connected in sequence to form a part of the optical fiber loop that needs to be formed during the detection, so as to transmit the communication light and detect the on-off status of the optical fiber.

[0040] In some embodiments, the first channel 401 and the second channel 402 both extend along a straight line.

[0041] The first channel 401 and the second channel 402 both extend in a straight line, which can improve the transmission efficiency and transmission quality of the communication light, reduce the signal attenuation of the communication light, and also simplify the difficulty of processing and installation.

[0042] In some embodiments, the first channel 401 and the second channel 402 are arranged in parallel, so that the transmission efficiency of the communication light can be further improved.

[0043] See also Figure 2 and Figure 5 In some embodiments, the communication optical detector 100 further includes a first sleeve 6 and a second sleeve 7. The first sleeve 6 is disposed in the first channel 401, and the second sleeve 7 is disposed in the second channel 402. Along the extension direction of the first channel 401, at least a portion of the first collimator 1 extends into one end of the first sleeve 6, and the other end of the first sleeve 6 is configured to allow the signal transmitting end 501 of the optical cable 5 to be tested to extend therein. Along the extension direction of the second channel 402, at least a portion of the second collimator 2 extends into one end of the second sleeve 7, and the other end of the second sleeve 7 is configured to allow the signal receiving end 502 of the optical cable 5 to be tested to extend therein.

[0044] A first sleeve 6 is provided in the first channel 401, and a second sleeve 7 is provided in the second channel 402, so that the first collimator 1 is aligned with the signal transmitting end 501 as much as possible, and the second collimator 2 is aligned with the signal receiving end 502 as much as possible, so as to reduce signal loss. The first sleeve 6 and the second sleeve 7 can also help fix the position of the optical cable 5 to be tested, reduce the shaking of the optical cable 5 to be tested in the first channel 401 and the second channel 402, and maintain the stability of the optical path.

[0045] See also Figures 2 to 5In some embodiments, the fixing seat 4 is provided with a first stopper 411 and a second stopper 412. Along the extension direction of the first channel 401, the first stopper 411 and the second stopper 412 are arranged at intervals and are configured to stop at the two ends of the first sleeve 6 respectively. The fixing seat 4 is provided with a third stopper 413 and a fourth stopper 414. Along the extension direction of the second channel 402, the third stopper 413 and the fourth stopper 414 are arranged at intervals and are configured to stop at the two ends of the second sleeve 7 respectively.

[0046] The first stopper 411 and the second stopper 412 prevent the first sleeve 6 from falling out of the first channel 401, and the third stopper 413 and the fourth stopper 414 prevent the second sleeve 7 from falling out of the second channel 402, so as to avoid the first sleeve 6 and the second sleeve 7 being pulled out of the fixing seat 4 when the optical cable 5 to be tested is pulled out of the first channel 401 and the second channel 402 after the test is completed.

[0047] In some embodiments, the side wall of the first sleeve 6 is provided with a first notch 601. The first notch 601 penetrates the first sleeve 6 along the axis extension direction of the first sleeve 6. The first sleeve 6 is configured to be able to produce elastic deformation to reduce the caliber through the first notch 601. The side wall of the second sleeve 7 is provided with a second notch. The second notch penetrates the second sleeve 7 along the axis extension direction of the second sleeve 7. The second sleeve 7 is configured to be able to produce elastic deformation to reduce the caliber through the second notch.

[0048] A first notch 601 is provided on the side wall of the first sleeve 6, and a second notch is provided on the side wall of the second sleeve 7, so that the cross-sections of the first sleeve 6 and the second sleeve 7 are incomplete rings, and both the first sleeve 6 and the second sleeve 7 can produce elastic deformation. When the first sleeve 6 and the second sleeve 7 are respectively placed into the first channel 401 and the second channel 402, the caliber can be reduced, which is convenient for installation and can also avoid damage to the first sleeve 6 and the second sleeve 7; after being placed in place, the inner wall of the first channel 401 will constrain the first sleeve 6, so that the outer peripheral wall of the first sleeve 6 fits with the inner wall of the first channel 401, and the inner wall of the second channel 402 will constrain the second sleeve 7, so that the outer peripheral wall of the second sleeve 7 fits with the inner wall of the second channel 402.

[0049] See also Figure 5 and Figure 6In some embodiments, along the extension direction of the first channel 401, the fixing seat 4 is provided with a first connection portion 441 in a protruding manner. The first channel 401 runs through the first connection portion 441, and the second stop portion 412 is located in the first connection portion 441. A third notch 4411 is provided on the side wall of the first connection portion 441. The third notch 4411 is configured to allow an external structure to extend into the first channel 401 to squeeze the first sleeve 6. Along the extension direction of the second channel 402, the fixing seat 4 is provided with a second connection portion 442 in a protruding manner. The second channel 402 runs through the second connection portion 442, and the fourth stop portion 414 is located in the second connection portion 442. A fourth notch 4421 is provided on the side wall of the second connection portion 442, and the fourth notch 4421 is configured to allow an external structure to extend into the second channel 402 to squeeze the second sleeve 7.

[0050] Since the first stopper 411 and the second stopper 412 are provided in the first channel 401 to prevent the first sleeve 6 from slipping out, the third stopper 413 and the fourth stopper 414 are provided in the second channel 402 to prevent the second sleeve 7 from slipping out. A first connecting portion 441 and a second connecting portion 442 are provided on one side of the fixing seat 4, and a third notch 4411 is provided on the side wall of the first connecting portion 441, and a fourth notch 4421 is provided on the side wall of the second connecting portion 442; in this way, it is convenient to take out the first sleeve 6 and the second sleeve 7 for replacement.

[0051] Based on some of the aforementioned embodiments, the side wall of the first sleeve 6 is provided with a first notch 601, and the first sleeve 6 is installed into the first channel 401 from the side of the first channel 401 close to the optical cable 5 to be tested, and the diameter of the first sleeve 6 is reduced through the first notch 601 to avoid interference between the first sleeve 6 and the second stopper 412 when installing the first sleeve 6; when the first sleeve 6 is placed in place, the first sleeve 6 will fit with the inner wall of the first channel 401. When the first sleeve 6 needs to be taken out for replacement, the diameter of the first sleeve 6 is reduced by using a tool through the third notches 4411 on the first connecting portion 441, and the first sleeve 6 is taken out through the first connecting portion 441. The side wall of the second sleeve 7 is provided with a second notch (not shown in the figure), and the second sleeve 7 is installed into the second channel 402 from the side of the second channel 402 close to the optical cable 5 to be tested, and the diameter of the second sleeve 7 is reduced through the second notch to avoid interference between the second sleeve 7 and the fourth stopper 414 when installing the second sleeve 7; when the second sleeve 7 is put in place, the second sleeve 7 will fit with the inner wall of the second channel 402. When the second sleeve 7 needs to be taken out for replacement, the diameter of the second sleeve 7 is reduced by using a tool through the plurality of fourth notches 4421 on the second connecting portion 442, and the second sleeve 7 is taken out through the second connecting portion 442.

[0052] In some embodiments, the fixing seat 4 is provided with a fixing portion 420. The fixing portion 420 is provided with a first fixing hole 4201 and a second fixing hole 4202. The first fixing hole 4201 is communicated with the first channel 401. The first collimator 1 extends into the first channel 401 through the first fixing hole 4201, and the first collimator 1 abuts against the inner wall of the first fixing hole 4201. The second fixing hole 4202 is communicated with the second channel 402. The second collimator 2 extends into the second channel 402 through the second fixing hole 4202, and the second collimator 2 abuts against the inner wall of the second fixing hole 4202.

[0053] Since in some embodiments, the first collimator 1 and the second collimator 2 are the parts with the collimating lenses extending into the first channel 401 and the second channel 402, the first collimator 1 abuts against the inner wall of the first fixing hole 4201 and the second fixing hole 4202 abut against the inner wall of the second fixing hole 4202 through the first fixing hole 4201 and the second fixing hole 4202 provided in the fixing portion 420, thereby ensuring that the positions of the first collimator 1 and the second collimator 2 are fixed in the fixing seat 4, thereby reducing the possibility of the first collimator 1 and the second collimator 2 being loose relative to the fixing seat 4 during the use of the communication light detector 100. The first fixing hole 4201 and the second fixing hole 4202 limit the first collimator 1 and the second collimator 2 in the radial direction for easy alignment.

[0054] In some embodiments, the fixing seat 4 is provided with a first stop wall 431. In the direction from the first fixing hole 4201 to the first channel 401, the first collimator 1 abuts against the first stop wall 431 along the radial direction of the first fixing hole 4201 to restrict the length of the first collimator 1 extending into the first channel 401. The fixing seat 4 is provided with a second stop wall 432. In the direction from the second fixing hole 4202 to the second channel 402, the second collimator 2 abuts against the second stop wall 432 along the radial direction of the second fixing hole 4202 to restrict the length of the second collimator 2 extending into the second channel 402.

[0055] See also Figure 3 and Figure 4 The first stop wall 431 is arranged on a side of the first fixing hole 4201 close to the detection optical cable 3, so that the first collimator 1 reaches a preset depth when it extends into the first channel 401; the second stop wall 432 is arranged on a side of the second fixing hole 4202 close to the detection optical cable 3, so that the second collimator 2 reaches a preset depth when it extends into the second channel 402.

[0056] Since a portion of the first collimator 1 is located in the first channel 401 and another portion is located in the first fixing hole 4201, the same is true for the second collimator 2; the first stop wall 431 is used to constrain the length of the first collimator 1 in the first channel 401, and the second stop wall 432 is used to constrain the length of the second collimator 2 in the second channel 402, ensuring non-contact docking between the first collimator 1 and the second collimator 2 and the optical cable 5 to be tested. At the same time, the first stop wall 431 and the second stop wall 432 are also easy to install, ensuring the position accuracy of the first collimator 1 and the second collimator 2.

[0057] In some embodiments, the detection optical cable 3 is connected to the same side of the fixing base 4, and a plurality of guide portions 450 are provided on a side of the fixing base 4 away from the detection optical cable 3. The plurality of guide portions 450 enclose a guide channel 403. The guide channel 403 is connected to the first channel 401 and the second channel 402. The guide channel 403 covers an end of the first channel 401 for the signal transmitting end 501 to extend into. The guide channel 403 covers an end of the second channel 402 for the signal receiving end 502 to extend into.

[0058] A plurality of guide portions 450 are enclosed to form a guide channel 403. The plurality of guide portions 450 can cover the portion of the optical cable 5 to be tested that is in contact with the fixing seat 4 to provide protection. The guide channel 403 can provide guidance for the signal sending end 501 and the signal receiving end 502 of the optical cable 5 to be tested to extend into the first channel 401 and the second channel 402.

[0059] In some embodiments, when the first channel 401 and the second channel 402 are arranged in parallel, the fixing seat 4 provides two "interfaces", and a further guiding structure can be arranged on the inner wall of the guiding channel 403 to allow the optical cable 5 to be inserted more quickly.

[0060] See also Figure 7 In some embodiments, the communication optical detector 100 further includes a protective cover 8. The protective cover 8 is detachably connected to the fixing seat 4, and the protective cover 8 covers the detection optical cable 3.

[0061] A protective cover 8 is detachably connected to one side of the fixing seat 4 close to the detection optical cable 3. The protective cover 8 can provide protection for the optical cable 5 to be tested, reduce damage to the optical cable 5 to be tested caused by external impact, extend the service life, and also play a role in waterproofing and dustproofing.

[0062] In some embodiments, the communication light detector 100 further includes a dustproof head 9 , which is disposed in the guide channel 403 .

[0063] When the communication light detector 100 is not in use, the dustproof head 9 is inserted into the guide channel 403 to prevent dust from entering the first channel 401 , the second channel 402 , and the first sleeve 6 and the second sleeve 7 therein.

[0064] The communication optical detector 100 provided in some embodiments of the present application, the interfaces used by the signal transmitting end 501 and the signal receiving end 502 of the optical cable 5 to be tested may be SC (Subscriber Connector), MPO (Multi-fiber Push-On), SN (Small Form-factor Pluggable), MTP (Multi-fiber Termination Pull-off), or a combination thereof. The detection optical cable 3 and the optical cable 5 to be tested may be 8-core, 12-core, 16-core, or 32-core optical fibers.

[0065] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
