Product Overview
FWDM Device
The WDM passive components, based on thin film filter technology,
combine all network services/signals over a single fiber. Low
insertion loss and high isolation between channels ensures reliable
network performance.
GEZHI Photonics supply various wavelength Filter WDM with Stainless
steel tube, ABS box, LGX cassette, 1U Rackmount ect.
Customized wavelength Filter WDM is available.
* 1310/1490/1550nm FWDM - for PON, FTTX and test instrument
*1310/1550nm FWDM - for WDM or DWDM optical communications
* 1310/1550/1625nm 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
* 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
* GPON, XGPON, RF Vedio for Next-Generation System
