The performance of the fiber optic connectors

The performance of the optical connector, the first optical properties, in addition to considering the fiber optic cable interchangeability, repeatability, tensile strength, temperature and frequency of mating. (1) Optical properties: Optical performance requirements for fiber optic connectors, mainly loss and return loss of these two basic parameters inserted. Insertion loss (InsertionLoss) i.e. the connection loss is introduced by means of the connector and the effective optical fiber cable power caused by the loss of link. Insertion loss as low as possible, the general requirements should be less than 0.5dB. Return Loss (ReturnLoss, ReflectionLoss) is the optical power connector on the link reflex suppression, the typical value should not be less than 25dB. The practical application of the connector, a special pin surface after the polishing process can return loss greater, generally not less than 45dB.
