The performance of fiber optic connectors, we must first consider the optical properties, in addition to considering interchangeability, repeatability, tensile strength, temperature and mating cycles.
(1) Optical properties: optical performance requirements for fiber optic connectors, mainly insertion loss and return loss of these two basic parameters.
Insertion Loss Connection Loss (InsertionLoss) refers to the effective optical power loss due to the import of the connector link. Insertion loss as small as possible, general requirements should not exceed 0.5 dB.
Return loss (ReturnLoss, ReflectionLoss) refers to the suppression of the connector to link the reflection of the optical power, the typical value should not be less than 25 dB. The practical application of the connector, the surface of the plug after special polishing allows a higher return loss generally not less than 45dB.
(2) interchangeability, repeatability
Fiber optic connector is a common passive device, for the same type of fiber optic connectors, it can generally have any combination of uses, and can be used repeatedly, which to import the additional loss is generally in the range of less than 0.2 dB.
(3) The tensile strength to make fiber optic connectors and the general requirements for tensile strength should not be less than 90N.
General requirements, fiber optic connectors must have a temperature of -40oC to 70oC in normal use.
(5) Mating cycles
At present, fiber optic connectors can be inserted and removed more than 1000 times.
