The performance of optical fiber connectors, we should first consideration the optical properties, in addition to considering the 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.
The insertion loss (InsertionLoss) connection loss, refers to the effective optical power loss due to the import of the connector link. Insertion loss as small as possible, the general requirements should not be greater than 0.5dB.
Return Loss (ReturnLoss, ReflectionLoss) refers to the suppression of the connector to link optical power reflection, the typical value should not be less than 25dB. The practical application of the connector, the pin surface after a special polishing allows greater return loss is generally not less than 45dB.
(2) Interchangeability, repeatability
The fiber optic connector is a common passive devices, for the same type of fiber optic connectors, can generally be any combination of uses, and can be used repeatedly, which to import the additional loss is generally in the range of less than 0.2dB.
(3) Tensile strength to do fiber optic connectors, and general requirements for the tensile strength should be not less than 90N.
General requirements, fiber optic connectors must be temperature-40oC to 70oC the normal use.
(5) Mating cycles
At present, the fiber optic connectors Can be inserted and pull out over l000 times.
