Fiber optic attenuator is a kind of optical passive components, used in optical communication system optical power performance, fiber optic instrumentation debugging, correction, attenuation of the input fiber signal power, to prevent distortion of optical receivers due to the input optical power is too strong; the product is the use of metal ion doped attenuator fiber manufacturing, can be adjusted to the optical power to the required level; HYC provides SC fixed cathode and yang attenuator has the advantages of Easy installation, good interchangeability, high and low temperature resistance and other advantages, widely used in telecommunications networks, CATV, data centers and other fields.
1. Good interchangeability, stability and durability
Good repeatability, good abrasion resistance, good temperature stability. Reliability and performance, low insertion loss, average additional loss value is less than 0.2dB, high return loss, plugging and unplugging times greater than 1000 times.Technical specifications:
