The Cable 500 is a significantly more advanced version of the MPO connectors used in Cable 5. 00 has a multi-hole ferrule 542 instead of a single-hole ferrule 142, and the cable A larger component cover 527 and a larger connector cover 544 than their counterparts in module 200. 1. The cable 200 is the same as or substantially the same as cable 200, except that the cable 200 has a plurality of outer optical fibers. The outer portions of 104 are generally coaxial with the respective bores of the ferrules 542. The ferrule 542 is surrounded by a connector cover 544. In some aspects, the connector cover 544 functions as a housing. The housing may be configured to surround the ferrule as known to those skilled in the art. A connector body, a slidable cover surrounding the connector body, and an adapter or other termination. A mating latch portion, such as a hook, of the end unit is engaged to connect the housing to the termination unit. and a latch portion that engages the cable and thus couples the cable to the termination unit. In the illustrated example, a connector cover 544 defines the bore end of the ferrule 542. Rule 542 controls the transmission of optical signals through respective ends of the outer optical fibers in a controllable manner. Each of the outer optical fibers 104 is supported and may have a terminal or other termination unit so that the outer optical fibers 104 can be Align the respective ends of the outer optical fibers for splice connection with the knit.

The alignment pins 543A and 543B extend from the ends of the alignment pins 543A and 543B. 43A, 543B are preferably disposed on either side of the ferrule 542 as shown. However, in other aspects, the alignment pins may be located at other locations or on the exposed end of the connector cover. may extend from other locations on the connector cover, including from one or more sides of the connector cover. At least a portion of any such alignment pins may be attached to the ends of these alignment members. 500 and such a terminal or other termination unit. The ferrule 542 is extended so that the connection stability with other termination units can be maintained. The direction in which the optical fiber extends within the ferrule. It can be assumed that there is.

[0076] Next, as shown in FIG. 6A, the cable 600 is inserted into the component section 220. and connector section 620 instead of connector section 140. and at least one hinge pin 660 in place of the flexible cover 260. Component section 620 is the same as or substantially the same as cable 200, except that it includes: The component section 620 has parallel arms 631A, 631B extending from the component cover body 621. The connector section is the same as or substantially the same as the component section 220, except that the connector section further includes a connector section B. The connector section 640 extends from the connector cover body 641. 6. The connector section 650 is the same as or substantially the same as the connector section 140, except that it further includes an arm 651. As shown, arm 651 is arranged to fit between parallel arms 631A, 631B. While this configuration may be implemented as shown in FIG. 6B, in an alternative embodiment, this configuration may be implemented as shown in FIG. As in the example of 00', the arm extending from the component cover body extends from the connector cover body. It can also be reversed so that it can be configured to fit between parallel arms. The configuration of the connector section alternates between parallel arms in the component section. A single hinge pin 660 connects the arms 631A, 631B, 651, or in another embodiment, one The hinge pin extends through holes in the arms 631A, 651 only, and another hinge pin extends through holes in arms 631B, 651 only. Thus, connector section 6 40 can be rotated relative to component section 620 so that cable 600 is bent. In some aspects of the configuration of cable 600, the hinge pin is 6. The connector section 640 may be integral with the connector section 640 so as to protrude from the connector section. While in the embodiment of the cable 600', the hinge pin is The cover may be integral with the component cover body so as to protrude from the component cover body.

[0077] Similar to components section 220, components section 620 includes optical unit 125. A portion of the inner optical fiber 102 and a portion of the outer optical fiber 104 pass through it. Similar to connector section 240, connector section 640 has a passageway extending therethrough. The outer optical fiber 104 has a passage therethrough through which a portion of the outer optical fiber 104 extends. The spring 104 is a dual hinge that is inserted into each of the arms 631A, 631B, and 651. The pins 660 may extend between the two arms or may be inserted in all three arms. Alternatively, the hinge pins 660 may extend around a single hinge pin 660 that is connected to the hinge 660 .

[0078] In some embodiments, an inner arm, e.g., arm 651, is connected to an outer arm, e.g., arm The pressure can be applied from the cylinders 651A and 651B. Such pressure causes the connector section 640 to move relative to the component section 620 in a different state from the initial state. An external force is applied to the cable 600 to bend it into different bent or straight positions. In some embodiments, at least one The hinge pin 660 is attached to at least one of the arms 631A, 631B of the component section 620. One arm is pressed into the other arm, and the other arm is pressed into the connector section 640. In this manner, the connector section 640 can be inserted into the component section 620 by The bending of the wire 620 into a curved or straight state different from the initial state. In order to achieve this, it is necessary to apply an external force to the cable 600, and the component section 620 is then 4. The stator 600 may be prevented from rotating relative to the section 640. The component section 620 is attached to the connector section 640 to provide a ratchet effect. Thus, either the component section or the connector section can be produced. The release button on one side is pressed and the other side of the component section or connector section The passage of the teeth is caused by a lever or slide attached to or engaging the release button. The connector section 640 is forced into a bent position until it can circumvent the step. This configuration rotates in one direction and does not rotate in the opposite direction. 4. Any rotation or at least some rotation of the component section 620 relative to the connector section 640 Both can be used to prevent any large rotations.

[0079] When the cable 600 is in a bent state as shown in FIG. A larger portion of the component section 620 is in contact with the connector section 640 than in the normal state. In this way, the inner cable 600 is closer to the inner cable 602 when the cable 600 is in a bent state. An external force acting on the cable section 110 or the component section 620 may cause the cable 60 When cable 600 is in a straight state, the same external force is applied to the same position along cable 600. A torque smaller than the torque applied to the connector section 6 is applied to the connector section 7. 40. Thus, the cable 600 suppresses the torsional stress on the cable 600. The case is compact enough to fit into tighter spaces when needed. Offer bull.

[0080] Next, as shown in FIG. 7A, the cable 700 is connected to the component section 62. 0 instead of part section 720 and connector section 640 instead of connector section 740 and does not include the hinge pin 660.

The connector cover 740 includes a ball portion 751 extending from the connector cover body 741. The ball section 751 is the same as or substantially the same as the cutter section 640. As shown, the ball section 751 is Configured to fit within a socket defined by lip 731 and component cover body 721 While this configuration may be used in alternative embodiments, this may be achieved by using the cable 700' shown in FIG. For example, the lip can extend from the connector cover body and the ball portion can extend from the component cover. - can be inverted so that it can extend from the body. The socket forms a ball and socket type joint, and the connector section 740 is To bend 700, it can be rotated relative to part section 720. Similar to the component section 620, the component section 720 surrounds the optical unit 125 and A portion of the side optical fiber 102 and a portion of the outer optical fiber 104 extend therethrough. Similar to connector section 640, connector section 740 includes a passageway 753. A portion of the outer optical fiber 104 includes a passage 754 extending therethrough.

[0081] In some aspects, the ball portion 751 is secured by the lip 731 and the cover body 721. The connector section can be inserted by press-fitting into the socket that is fixed in place. The bend 740 is bent or straightened relative to the component section 720 in a different state from the initial state. An external force must be applied to the cable 700 to bend it into its natural shape, and the component section This can prevent the connector section 720 from rotating relative to the connector section 740.

[0082] When the cable 700 is in a bent state as shown in FIG. 7A, the cable 700 is in a straight state. A larger portion of component section 720 is in contact with connector section 722 than when in the upright position. 40. In this manner, the inner cable 700 is in a bent state. An external force applied to the cable section 110 or the component section 720 The same load applied at the same location along cable 700 when 700 is in a straight state The torque applied to the connector section by the external force is smaller than the torque applied to the connector section by the external force. Therefore, the cable 700 is subjected to a torsional stress on the cable 700. The case reduces weight while allowing it to be more compact and fit into tighter spaces when needed. Offer bull.

[0083] Next, as shown in FIG. 8, each of the cables 800 is connected to a component section. Component cover 827 of component section 820 is included instead of component cover 227 of component section 220.
