Embodiment 1

[0032] Such as figure 2 with 3 As shown, the optical insert with an isolator of the present application includes a sleeve 11 , an optical fiber ferrule 12 disposed in the sleeve 11 , and an isolator 20 . Wherein, the isolator 20 includes a separated isolation core 21 and a magnetic member 22, the isolation core 21 is arranged in the sleeve 11, and is located on the optical path of the optical fiber ferrule 12; the magnetic member 22 is suitable for being assembled outside the sleeve 11, and used The magnetic field is provided to the isolation core 21 in the bushing 11 . That is, before the optical insert 10 is used, the magnetic member 22 of the isolator 20 is not fixedly installed with the optical insert 10 , and the magnetic member 22 can be separated from the optical insert 10 . When the optical plug-in 10 is installed in the optical module, the magnetic member 22 of the isolator 20 is not installed together. At this time, the isolation core 21 is not in the magnetic fie...

Embodiment 2

[0038] Such as Figure 8 and 9 As shown, the optical module of the present application includes the optical interposer 10 with the isolator 20 of the above-mentioned embodiment, and also includes the encapsulating case 30 , the optical platform 40 and the light emitting end disposed in the encapsulating case 30 . Wherein, the optical platform 40 has a light emitting port 41, and the above-mentioned optical plug-in 10 with isolator 20 is installed at the light emitting port 41 to isolate the returning light entering the light emitting port 41, so as to prevent the returning light from entering the light emitting end and affecting the light. Transmitter stability.

[0039] Before the optical insert 10 with isolator 20 is installed in the optical module, the magnetic member 22 of the isolator 20 is not fixedly installed with the optical insert 10 , and the magnetic member 22 can be separated from the optical insert 10 . In this embodiment, after the optical plug-in 10 is fixedl...

Embodiment 3

[0042] Such as Figure 10 and 11 As shown, in this embodiment, the optical module includes a packaging case 30, an optical platform 40 disposed in the packaging case 30, a light emitting end and a light receiving end, wherein the optical platform 40 has a transmitting light port 41 and a receiving light port 42 , the transmitting optical port 41 is installed with the first optical insert 10a, that is, the optical insert with isolator in the above embodiment, and the receiving optical port 42 is installed with the second optical insert 10b, and the second optical insert 10b has no isolation core. The difference from Embodiment 2 is that in this embodiment, the magnetic member 22 of the isolator 20 is also the positioning part of the two optical inserts 10a, 10b, and the two optical components installed at the transmitting optical port 41 and the receiving optical port 42 The inserts 10 a , 10 b are positioned while providing a magnetic field to the spacer core installed in the...

Abstract

This application relates to the technical field of optical communication, and discloses an optical insert with an isolator and an optical module with the same. The optical insert with an isolator includes a sleeve, an optical fiber ferrule and an isolator disposed in the sleeve; Separate isolating core and magnetic component, the isolating core is arranged in the sleeve and located on the optical path of the fiber ferrule; the magnetic component is suitable for being assembled outside the sleeve to provide a magnetic field for the isolating core. This application separates the magnetic component of the isolator integrated in the optical plug-in from the isolation core, and the magnetic component can be installed outside the optical plug-in after the optical plug-in assembly is completed. It plays the role of isolation, and the optical signal can still be input into the optical plug-in to realize the alignment of the optical plug-in, which solves the problem of difficult assembly of the optical plug-in integrated with the isolator, and improves the assembly efficiency; and the magnetism is added at the end, and the versatility of the optical plug-in is more Well, the direction of the light can be selected by adjusting the direction of the magnetic field as needed.

Description

technical field [0001] The present application relates to the technical field of optical communication, in particular to an optical insert with an isolator and an optical module having the same. Background technique [0002] In the process of assembling the optical module, generally, the optical insert and the optical platform are assembled and fixed first, and then the transmitting component and / or the receiving component are assembled on the optical platform. Usually, when assembling, an external light source is used to input an optical signal into the optical interposer, and the optical signal is detected at the other end of the optical table to realize the alignment of the optical interposer. Its light path direction is opposite to the light output direction of the emitting component. [0003] With the continuous development of the optical module product market, the cost pressure is increasing, and a cost-reducing optical plug-in solution has appeared on the market, suc...
