Mô tả Sản phẩm

- Filter-based Wavelength Division Multiplexer (FWDM) is a kind of Filter WDM multiplexer based on the Thin Film Filter (TFF) technology.

- The FWDM combines or separates light at different wavelengths in a wide wavelength range and is extensively used in EDFA, Raman amplifiers, and WDM optical networks. Powerlink provides a series of FWDM multiplexers for FTTx constructions. Our FWDM product line covers different wavelength windows commonly used in optical fiber systems.

- All the FWDM multiplexers offer low insertion loss, low polarization dependence, high isolation and excellent environmental stability.

- FWDM T1550 R1310&1490 can achieve 1550/1310&1490 two channel optical signal multiplexing and demultiplexing, Making single optical fiber transmission capacity multiplier, Widely used in optical fiber network upgrading and CATV etc.

- Powerlink 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.

- As you might know, 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:

High Isolation
Low Loss
High Reliability
High channel isolation
Excellent environmental reliability
RoHS Compliant
