Description
● Filter WDM(FWDM):
FTTX Filter WDM module is based on Thin Film Filter (TFF) technology. The device combines or separates light at different wavelengths in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability.
FTTH/FTTx 1310/1550nm FWDM Filter WDM can realize the multiplexing and de-multiplexing of communication optical signals of 1310nm and 1550nm. It can expand the capacity of a single fiber to achieve bidirectional communication, so that widely used in optical network upgrade and expansion, or introduce new comprehensive business etc.
GEPON system itself works on 1310/1490, so CATV signal here is delivered over same fiber using 1550nm, and FWDM is a place where all this get's "mixed".
● Features:
● Low Insertion Loss
● High Channel Isolation
● Optical path epoxy free
● Excellent thermal stability and reliability
● High Isolation
● RoHS Compliant
● Application:
● CWDM and DWDM Network
● Add/Drop System
● CATV Fiber optic System
● Metro/Access Network
● Fiber Optical Amplifier
