3 Port 1510 1550nm FWDM Filter For DWDM Multi-Channel Optical Networks
Corephy FWDM is based on thin film filter technology, it has a smooth channel bandwidth and high isolation, low insertion loss and high environmental stability and reliability etc, very suitable for use in optical amplifier, CATV and FTTH applications.
Application for different FWDM
1310/1550nm FWDM - for WDM or DWDM optical communications
1480/1550nm FWDM - for high-power DWDM optical amplifier and EDFA
1510/1550nm FWDM - for DWDM multi-channel optical networks
980/1550nm FWDM - for high performance DWDM optical amplifier and EDFA amplifier
1310/1490/1550nm FWDM - for PON, FTTX and test instrument
1310/1550/1625/1650nm FWDM - for testing active fibers in service
1310/1490/1550/1625nm FWDM - for combining or separating 1625nm channel with three triplex wavelength 1310nm, 1490nm and 1550nm so that 1625nm channel can be added into the existing triplex FTTH system
