1, the requirements of the fixed connection fiber optic fixed connection is a key technology in the cable line. Requirements for fixed connections are the following: small connection loss, consistency is good; connection loss stability should be good, the general temperature range should not have additional loss; have sufficient mechanical strength and service life; operation should be as simple as possible, easy to construction operations; joint volume to be small, easy to place and protection; low cost, easy to process materials.
2, the requirements of the active connection For the requirements of the removable fiber optic connection, are currently using mechanical connectors to achieve. The main requirements are the following: connection loss should be small, single-mode fiber loss less than 0.5dB; should have good repeatability and interchangeability. After multiple insertion and removal and interchangeable accessories, there is still a good consistency; with good stability, the connector fastened insertion loss is stable, not affected by temperature changes; small size, light weight; have a certain strength; appropriate price.
3, the requirements of the temporary connection fiber temporary connection, you can also use the fusion splicer fusion. Requirement loss as low as possible, in the use of V-groove and capillary tube connection, must be added to the proportioning liquid, otherwise it can not eliminate the Fresnel reflection.
