Abstract
The utility model is applicable to the field of optical communication and transmission and provides a single fiber two-way transceiver, which comprises a laser (2), a metal shell (4) and an optical fiber interface (3), wherein a hollow cushion block (9) is arranged between the laser (2) and the metal shell (4), the centers of the cushion block (9), the laser (2) and the optical fiber interface (3) are on the same axis. The single fiber two-way transceiver replaces an adjusting ring (8) to control the distance between the laser (2) and the optical fiber interface (3) with the cushion block (9), thereby the single fiber two-way transceiver after welding has strong intensity, and the reliability and high and low temperature performances of the single fiber two-way transceiver are improved.
Description
Technical field
The utility model belongs to the optical communication transmission field, relates in particular to a kind of single fiber bi-directional transceiver.
Background technology
The single fiber bi-directional transceiver is that the collection sending and receiving are the electrooptical device of one, adopt the recovery technology, in same optical fiber, finish transmitting and receiving of light, use an optical fiber just can realize the transmitted in both directions of data, owing to have identical function with two fibres, thereby can save optical fiber, reduce cost, in the optical communication transmission, be widely used at present.
Fig. 1 shows the schematic construction of existing single fiber bi-directional transceiver, its production technology is: earlier isolator 5 and laser instrument 2, metal shell 4 are fixed, coupled fiber interface 3 ends then, by the distance between regulating ring 8 adjusting optical fiber interfaces 3 and the laser instrument 2, making optical fiber interface 3 obtain end face overlaps with the focus of laser instrument, so that it is output power reaches requirement, at last that regulating ring 8 is fixing with metal shell 4 and optical fiber interface 3 welding.But because regulating ring 8 walls are thin, welding back intensity difference has reduced the reliability and the high temperature performance of single fiber bi-directional transceiver, and luminous power mutabilityization during single fiber bi-directional transceiver laser bonding.
The utility model content
The purpose of this utility model is: a kind of single fiber bi-directional transceiver is provided, is intended to solve existing single fiber bi-directional transceiver welding back intensity difference, reliability and the also relatively poor problem of high temperature performance of using regulating ring.
The purpose of this utility model is achieved in that
A kind of single fiber bi-directional transceiver, comprise laser instrument (2), metal shell (4), optical fiber interface (3), the cushion block (9) that hollow is arranged between described laser instrument (2) and metal shell (4), the center of cushion block (9), laser instrument (2), optical fiber interface (3) is on same axis.
Described single fiber bi-directional transceiver does not comprise regulating ring (8).
The wall thickness of described cushion block (9) is not thinner than the wall thickness of metal shell (4).
Outstanding advantage of the present utility model is: the utility model is by using the distance of 3 of cushion block 9 replacement regulating rings, 8 control laser instruments 2 and optical fiber interfaces, make the single fiber bi-directional transceiver intensity height after the welding, and improved the reliability and the high temperature performance of single fiber bi-directional transceiver.
Description of drawings
Fig. 1 is the structural representation of existing single fiber bi-directional transceiver;
Fig. 2 is the structural representation of the single fiber bi-directional transceiver that provides of the utility model;
Wherein, 1, receiver; 2, laser instrument; 3, optical fiber interface; 4, metal shell; 5, isolator; 6,0 degree filter plate; 7,45 degree filter plates; 8, regulating ring; 9, cushion block.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 2 shows the schematic construction of the single fiber bi-directional transceiver that the utility model provides.
In the utility model, do not re-use regulating ring 8 in the single fiber bi-directional transceiver, but between laser instrument 2 and metal shell 4, added the cushion block 9 of hollow, the center of cushion block 9, laser instrument 2, optical fiber interface 3 is on same axis, realize the distance of adjusting laser instrument 2 and optical fiber interface 3 by the cushion block 9 that uses different axial widths, so that the end face of optical fiber interface 3 overlaps with the focus of laser instrument 2, make output power reach requirement, by welding cushion block 9 is fixedlyed connected with laser instrument 2, metal shell 4 again.The wall thickness of cushion block 9 is not thinner than the wall thickness of metal shell 4.
Because cushion block 9 walls are thicker, weld back single fiber bi-directional transceiver intensity height, improved the reliability and the high temperature performance of single fiber bi-directional transceiver, luminous power is not variable yet during welding.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
1. single fiber bi-directional transceiver, comprise laser instrument (2), metal shell (4), optical fiber interface (3), it is characterized in that, the cushion block (9) that hollow is arranged between described laser instrument (2) and metal shell (4), the center of cushion block (9), laser instrument (2), optical fiber interface (3) is on same axis.
2. single fiber bi-directional transceiver as claimed in claim 1 is characterized in that, described single fiber bi-directional transceiver does not comprise regulating ring (8).
