3 Ports FWDM Device

What is FWDM?

Filter Wavelength Division Multiplexer (FWDM) is based on mature thin film filter technology. It has the characteristics of wide channel bandwidth, low insertion loss, high channel isolation, high environmental stability and reliability, and is widely used in single-mode optical fiber communications. System and DFA.

FWDM Splitter, also known as Filter WDM Splitter and Filter WDM, along with dense WDM splitter and coarse WDM splitter, are the most commonly used WDM device in construction of PON.
