Description
Technical field
The invention belongs to technical field of optical fiber communication, and in particular to one kind is for relative rotation equipment in optical fiber telecommunications system
Between optical signal transmission optical fiber collimator docking style single optical rotary joint and its installation method.
Background technique
Fiber optic communication makes it be used widely because of many merits such as its enormous bandwidth, common-path interference and minor losses.
It needs to carry out fiber optic communication between the equipment mutually rotated at two in certain applications, such as marine towing fiber optic communication hawser
Between lash ship, between vehicle and radar antenna between fire balloon and earth station etc..These application scenarios require light rotation
Connector.The stationary parts and rotary part of optical rotary joint are individually fixed between the equipment that two mutually rotate, it can
To realize the fiber optic communication between two equipment.
Common single optical rotary joint is aligned by the optical fiber collimator of two relative rotation, or passes through two naked light
It is fine directly to dock.The optical rotary joint directly docked using bare fibre, at docking unavoidably there is because off-axis aberrations,
Angular deviation and axial deviation and caused by power loss, cause since the core diameter of Standard single-mode fiber is smaller to these errors
It is very sensitive, biggish fiber optic communication power loss therefore also is caused, is brought very to designing and manufacturing for optical rotary joint
Big difficulty.Structure is complicated for the optical rotary joint of bare fibre Direct-type, and very high to part processing precision requirement, thus seldom
It is used.United States Patent (USP) US23300281A proposes a kind of optical rotary joint of optical fiber collimator docking style, although can drop
It is low that part processing precision is required, but the gap between bearing will cause the variation in collimator orientation, to cause to rotate
The insertion loss variation of device in journey is bigger.
In addition, optical fiber collimator alignment of the common single optical rotary joint by two relative rotation, multi-core optical rotation
Turning connector generally uses the optical path of mechanical axis of rotation as benchmark.In the manufacturing process of this optical rotary joint, need
The orientation of optical fiber collimator is adjusted, so that turn of the central axis of optical fiber collimator output beam and optical rotary joint
Moving axis is overlapped, this is a relatively difficult and complicated process.Common method has speckle analysis method and gradually proof method.

Position and the angle parameter for penetrating hot spot, are then calculated according to related algorithm, and the angles and positions parameter of collimator is adjusted；Most
After carrying out confirming performance using CCD monitoring device and stationary end collimator eventually, the collimator of round end is permanently fixed, this side
Method needs to carry out expensive CCD monitoring device investment, and carries out the algorithm research of matched fixture exploitation and various products.
Gradually proof method step 1: first collimator is temporarily fixed in rotary shaft by mechanical precision with readily removable glue
It in heart hole, is exchanged in the collimator of stationary end collimator and rotation, by the loss of the 360 degree rotation of the two collimators
Variation is adjusted to minimum, and the general first step is adjustable to 10dB or so；Step 2: the collimator of rotation is removed and clears up glue
Water, then loss is adjusted to minimum by turning end collimator on the basis of the collimator of stationary end, it is general to require to be less than 0.5dB,
It is fixed in the centre bore of rotary shaft with readily removable glue again, at this time again by the Dissipation change tune of the 360 degree rotation of two collimators
It is whole to arrive minimum, generally it is adjustable to 3dB or so；Step 3: repeating second step multipass, the Dissipation change of 360 degree rotation is adjusted
To the required value of product, generally 0.5dB, while maximum insertion is less than the required value of product, generally 1.5dB.Gradually
Proof method needs to expend a large amount of manpower and time, and fabrication cycle is long, does not have rapid throughput.
