What is PV connector properties when purchasing PV connector

 The performance of PV connectors, above all is the optical properties, in addition to fiber optic connectors should also be considered interchangeable, repetitive, tensile strength, temperature, and mating frequency.

(1) optical properties: optical connectors for optical performance requirements, mainly insertion loss and return loss of these two basic parameters. Insertion Loss that connection loss, is due to import the connector link caused the effective optical power loss. Insertion loss as small as possible, the general requirements should be less than 0.5dB. Return Loss is the connector on the link optical power reflection suppression, the typical value should not be less than 25dB. Practical application of the connector, pin surface after a special polishing process, can make the return loss greater, generally not less than 45dB. (2) interchangeability, repeatability is the common fiber optic connectors, passive components, for the same type of fiber optic connectors, can generally be used in any combination, and can be used repeatedly, resulting into additional losses are generally within less than 0.2dB.

(3) The tensile strength of fiber-optic connector for a good job, generally requires its tensile strength is not less than 90N.
