A the first mounting groove 8 being parallel to each other, 2 upper surface of the second installing plate are provided with several the second mounting grooves 9 being parallel to each other, institute
State after the first optical fiber 3 removes coat and be arranged in the first mounting groove 8, the second optical fiber 4 is arranged on the second peace after removing coat
In tankage 9, and the first optical fiber 3,4 front-back staggered of the second optical fiber, the cover board 7 are fastened on the installation of the first installing plate 1, second respectively
2 upper surface of plate for the first optical fiber 3 is fixed in the first mounting groove 8, the second optical fiber 4 is fixed in the second mounting groove 9,
One end of first optical fiber 3, one end of the second optical fiber 4 are connected with fibre-optical splice 5.The front and rear mistake of first optical fiber 3, the second optical fiber 4
Position is set, and totally transmitting-receiving closeness is high, and two layers of spaced apart above and below transmitting-receiving point, making can between the first optical fiber 3 and the second optical fiber 4
Interactional region is smaller, the crosstalk being effectively reduced between receiving and transmitting signal, meanwhile, before the first optical fiber 3, the second optical fiber 4
After shift to install and be layered setting and can directly result in distance between VCSEL chips and PD chips and become larger, easy to radiate, this practicality is new
Type can be adapted to low channel transfer, it can also be used to which high channel transmits, and the transmitting of such as 12 tunnels, 12 tunnels receive, the first mounting groove 8, the
The number of two mounting grooves 9 is typically four, eight, 12,24 etc., and in the utility model, the first optical fiber 3 can receive light
Fine or launching fiber；Second optical fiber 4 can be launching fiber or reception optical fiber.
First mounting groove 8, the second mounting groove 9 are V-groove, U-type groove or rectangular channel, in order to the first optical fiber 3, second
The placement and fixation of optical fiber 4, make the first optical fiber 3, the second optical fiber 4 be less likely to occur to move.
First optical fiber 3, the cutting angle A of the second end face of the optical fiber 4 away from fibre-optical splice 5 are more than 40 ° and are less than
50°.Cutting angle A is easy to the reflection of light, and can reduce the loss of light energy.
The cover board 7 is glass cover-plate, and 1 and second installing plate 2 of the first installing plate is glass mounting plates.
First installing plate, 1 upper surface is provided with least one groove 6 and fractures for avoiding the first optical fiber 3 from being pressurized.
