본문
In-Line Attenuator is used to attenuate optical power in an optical system. In-Line Attenuator can be used to replace the conventional cable assembly and attenuator combination.
It is compact, multi-purpose passive device designed to operate at the 1310 and 1550nm wavelengths. Korea Optron Corp. provides Attenuated Patch Cords with various connector styles SC, ST, FC, MU and hybrid type.
