Description
Technical field
The present invention relates to fiber optic communication field, more particularly to a kind of optical module.
Background technology
Optical fiber is a kind of light conduction work for producing total reflection in the fiber made of glass or plastics using light and being formed
Tool.Optical module is generally used for realizing the conversion between photoelectricity, and optical module generally includes light transceiver and is used for and optical fiber
The fiber adapter of connection.
Fiber adapter can be divided into FC (Ferrule Connector, casing joint), ST by the structure type of joint
(Stab＆Twist, round joint), SC (Square Connector, square joint), LC (LucentConnector, small-sized side
Type joint) etc. form, by the way of contact of optical fiber can be divided into PC types (Physical Contact, physics end contact, joint cut
Face is flat), UPC types (Ultra PhysicalContact, ultra physical end contact, contact cross-section are spheres), APC types
(Angled Physical Contact, angle physics end face, contact cross-section is inclined-plane).
As shown in figure 1, it is the structural representation of SC/UPC type fiber adapter on conventional art.SC/UPC type optical fiber is fitted
Orchestration 100 includes housing 101 and the lock pin 102 in housing 101.It is equipped with lock pin 102 for propagating optical signal
Fibre core, the end face 1021 of lock pin 102 are used to be connected with external fiber socket, and the end face 1021 is plane；Lock pin 102 it is another
End face 1022 is used to receive what light transceiver was launched optically coupling in optical fiber or by optical fiber optically coupling to light launching
In device, when the illumination sent to reduce light transceiver is mapped to end face 1022 inside reflected light return light transceiver, end
Face 1022 is arranged to inclined plane.
When fiber adapter 100 is coupled with the light that light transceiver is sent, because end face 1022 is inclined plane, from light
It is between light axis and the axis of the housing of fiber adapter that fine adapter 100 is emitted and not parallel and there is certain angle
α, and the emergent light of light transceiver transmitting generally also has certain angle of inclination, therefore, has inclination angle carrying out two
When clear aperature is coupled, the coupling efficiency of maximum can just be found by being necessarily required to rotation.As shown in Fig. 2 Fig. 2 is conventional art
Coupling effect of the light beam that the light beam of middle fiber adapter outgoing receives with light transceiver when fiber adapter does not rotate
Figure, light beam (a) is the light beam of the outgoing of fiber adapter in Fig. 2, and light beam (b) is the light beam of the reception of light transceiver, coupling
Closing light (c) is light beam after light beam (a) and light beam (b) coupling.Due to the light axis and the light axis of light beam (b) of light beam (a)
With certain angle, therefore, when light beam (a) and light beam (b) couple, if fiber adapter 100 does not rotate, light is coupled
(c) efficiency is very low.Received as shown in figure 3, Fig. 3 is the light beam that fiber adapter is emitted in conventional art with light transceiver
Light beam in the postrotational coupling effect figure of fiber adapter, light beam (d) is the light beam of fiber adapter outgoing, and light beam (e) is
The light beam that light transceiver receives, after light beam (d) and light beam (e) couple after coupling light (f) is rotated for fiber adapter
Light beam.After fiber adapter rotation, the coupling efficiency of light beam (d) and light beam (e) improves.
Therefore, effect is coupled with the maximum luminous power of fiber adapter in the conventional technology in order to obtain light transceiver
Rate, spin fiber adapter must be wanted.
On the other hand, the illumination sent to further reduce light transceiver is mapped to fiber adapter 100 and optical fiber
During end face (i.e. the end face 1021 in Fig. 1) of contact, inside reflected light return light transceiver, people are also by fiber adapter
End face 1021 make inclined plane, i.e. APC types are made in the end face of fiber adapter and optical fiber contact.But because of fiber adapter 100
The end face being connected with optical fiber is that (end face 1021 of fiber adapter 100 itself is inclined-plane to two inclined end faces, the end face of optical fiber
And inclined-plane) be connected, therefore cooperation of the fiber adapter 100 with optical fiber between the two is that must have that accurate angle is corresponding,
I.e. optical fiber is for fiber adapter 100, it is impossible to rotates, can only be that a fixed angle is coordinated；Simultaneously as light
Transceiver coupling needs, and fiber adapter must carry out coupling welding with light transceiver as an entirety, so
Need must also to have between fiber adapter and light transceiver that accurate angle is corresponding, i.e., light transceiver is fitted with optical fiber
Orchestration can only be that a fixed angle is assembled, and after fixing assembling, fiber adapter is unable to opposed optical fibers and rotated.Namely
It is to say, if to ensure maximum luminous power coupling efficiency, fiber adapter must be rotated, and after fiber adapter rotation then
It can not ensure that the end face 1021 of fiber adapter 100 is accurately docked with the inclined end face of optical fiber, whereas if to ensure that optical fiber is fitted
The end face 1021 of orchestration is accurately docked with the inclined end face of optical fiber, then fiber adapter is unable to the rotation of relative light emission receiver,
The coupling efficiency of the laser of fiber adapter and light transceiver can not be ensured.
Therefore, on the one hand, be mapped to fiber adapter 100 and optical fiber contact to reduce the illumination of light transceiver transmitting
End face when reflected light return light transceiver inside, improve return loss, light transceiver, fiber adapter and optical fiber
Must all there is accurate angle corresponding between three and can not be rotated；On the other hand, in order to ensure fiber adapter be emitted
Light beam and the light beam that receives of light transceiver between coupling efficiency, fiber adapter must be rotated.Therefore, optical fiber
It is conflicting that adapter relative light emission receiver, which rotates and obtained both maximum luminous power coupling efficiencies,.
Therefore, when the end face and the end of fiber adapter and optical fiber contact that fiber adapter couples with light transceiver
When face is inclined plane, how to solve the rotation of fiber adapter relative light emission receiver and obtain maximum luminous power coupling efficiency
Contradiction between the two is current urgent problem.
