Aviation plug
I. Optical performance of optical fibre plugs
Optical performance requirements of optical fibre aviation plug is mainly insertion loss and return loss of the two most basic parameters.
Insertion loss (InsertionLoss) is due to connector conduction caused by the loss of effective optical power of the link. Insertion loss is as small as possible, generally requires no more than 0.5dB.
Return loss (ReflectionLoss) refers to the connector to inhibit the link optical power reflection ability, its typical value should not be less than 25dB. In the actual application of the connector, the pin surface is specially polished, so that the return loss is larger, generally not less than 45dB.
2, the interchangeability and repeatability of fibre optic aviation plugs
Fiber optic connector is a universal passive device. For the same type of optical fibre connector, it can be used in any combination and can be reused. Therefore, the additional loss of the lead is generally less than 0.2 dB.
3, fibre optic aviation plug tensile strength
Good optical fibre aerial plugs, generally require a tensile strength of not less than 90N.
M12 aviation connector
4, fibre optic aviation plug temperature
Usually, fibre optic connectors must be able to work at temperatures between -40oC and +70oC.
