Description
PWDM is a combination of wavelength division multiplexing and photodetector, which is widely used in triple play, CATV, FTTH, fiber amplifier, etc. Based on mature thin film filtering technology, PWDM photodetector has flat channel bandwidth and high isolation, low insertion, high environmental stability and reliability. It is widely used in the upgrade and expansion of optical networks, or the introduction of new integrated services (CATV, TELECOM, triple play - PON + EOC), etc.
Features
Low insertion loss
Low PDL
High channel isolation
Excellent environmental reliability
Applications
WDM system
CATV
