Description
Dense Wavelength Division Multiplexer (DWDM) multiplexes optical signals of different wavelengths onto one optical fiber (multiplexing), or separates multiple optical channels multiplexed into one optical fiber by wavelength (demultiplexing). 100GHz/200GHz channel spacing dense optical wavelength division multiplexer/demultiplexer uses mature multi-cavity dielectric film to achieve optical filtering, has good wavelength stability, is encapsulated by sealing process, and has high environmental stability.
Features
Low Insertion Loss
Wide pass band
High channel
High stability and reliability
Epoxy free on optical path
Applications
Channel Add/Drop
DWDM Network
Wavlength Routing
CATV fiberoptic System
Fiber optical amplifier
