fiber connector is a kind of commonly used products, used in optical fiber repeatable plug connection between devices, also known as optical fiber joint activities, used for the large capacity high speed transmission system, also requires a reflection. What are the performance characteristics of fiber optic equipment connector? Below small make up to introduce, hope you can help to you.

the performance of the optical fiber connector, the first is optical performance, in addition to consider the compatibility of optical fiber connector, repeatability, tensile strength, temperature and the number of plug, etc.

( 1) Optical performance: in the light of the optical fiber connector performance requirements, mainly is the insertion loss and return loss both zui basic parameters.

insertion loss ( InsertionLoss) The connection loss, refers to the link caused by connector import optical power loss effectively. Insertion loss as small as possible, general requirements should not be greater than zero. 5分贝。

return loss ( ReturnLoss ReflectionLoss) Refers to the optical power connector to link reflex inhibitory ability, its typical values should not be less than 25 db. Practical application of the connector, pin after the special surface polishing treatment, can make the return loss is bigger, generally not less than 45 db.

( 2) Interchangeability, repeatability

optical fiber connector is gm's passive components, for the same type of optical fiber connector, generally can be used in any combination, and can be used repeatedly, and import the additional loss are generally less than 0. The range of 2 db.

( 3) Tensile strength

to make optical fiber connector, general requirements the tensile strength shall be not less than 90 n.

( 4) Temperature

general requirements, optical fiber connector must be in - 40 oc ~ + 70 oc temperatures can be normal use.

( 5) Plug number

basic can now use the optical fiber connector plug l000 more than once.
