Description

The ST optical fiber attenuator is a suspended type of passive optical component, used for adjusting the optical power performance in optical communication systems, calibrating the standard of optical fiber instruments, and attenuating optical signals. It is made of doped metal ion attenuating optical fibers, which can adjust the optical power to the required level. It features small insertion loss fluctuation, high compressive strength, high installation density, and uses precise ceramic sleeves and ceramic ferrules to ensure long-term stable mechanical and optical performance.

Features

Low insertion loss, high return loss, and good interchangeability
High-precision mechanical dimensions
High reliability and stability
500-cycle mating test, good repeatability

Applications

FTTH, ODF
Telecommunication network, LAN, optical communication system
Optical fiber CATV, optical fiber sensor
Optical fiber broadband access network
Video transmission and Testing instruments
Optical fiber testing instruments and meters
