1550nm Pass/980nm Reflect FWDM 980/1550nm Filter WDM optic fiber splitter
Description
The 1310/1550nm Filter Wavelength Division Multiplexer is based on environmentally stable thin-film filter technology. The devices combine or separate light at different wavelength in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating. These components have been extensively used in EDFAs, Raman amplifiers, WDM networks and fiber optical instruments.
WDM is based on proven thin-film folter technology.This WDM is widely used in fiber optical communication system and EDFA where flat and broad operating bands are needed.
