We say in the connector used in different environmental conditions, the connector itself also to different environmental requirements.

In 1, the fixed connection of optical fiber cable line requirements is one of the key technologies in the. The fixed connection request has the following several aspects: the connection loss of small, good consistency; connection loss stability is better, the general temperature range should not have additional loss; have adequate mechanical strength and service life; operation should be simple, easy operation; joint small size, ease of placement and protection; low cost easy processing, materials.

In 2, the movable connection request for a detachable fiber optic connection mode, are using mechanical connector to achieve. The demand mainly have the following several aspects: the connection loss to small, single mode optical fiber loss less than 0.5dB; should have good repeatability and interchangeability. Multiple plug with interchangeable parts, there are still good consistency; has good stability, after connecting fastener insertion loss of stability, not influenced by temperature variation; small volume, heavy weight to be light; have a certain strength; reasonable price.

In 3, the temporary connection temporary connection requirements of optical fiber, can also be used for welding machine welding. Requirements of loss as low as possible, in the V type groove and the capillary connection, must increase the ratio of liquid, or can not eliminate the Fresnel reflect
