Filter Type Multi-Mode Splitter (FMMC)

Filter type multi-mode splitter features stable split ratio with various light sources. The fused multi-mode coupler coupling ratio will change with the light source mode distribute. For the multi-mode fiber systems that may use different light sources, filter type multi-mode splitter can keep the constant split ratio for any type of light sources.

Key Features:

* Broad operating band
* Stable coupling ratio for any light source
* High stability and reliability


* Multi-mode fiber system

* Testing instruments
