Filter-based WDM Device (FWDM)
T1550nm/R1310/1490nm
Wavelength Division Multiplexer

Description
The filter wavelength division multiplexer series are based on environmentally stable thin-film filter technology. The devices combine or separate light at different wavelengths in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation, and excellent environmental stability. These components have been extensively used in EDFAs, Raman amplifiers, fiber sensor systems, WDM networks, and fiber optics instrumentation.

Features

• Based on thin-film filter technology and high wavelength stability
• Low polarization-dependent loss and high channel isolation
• Flat and wide passband
• Epoxy-free optical path and excellent reliability
• Telcordia GR-1221-CORE qualified and RoHS compliant

Applications

• WDM system
• CATV system
• Telecommunication network system
• Metro/Access networks
• EDFA
• Fiber optic instruments
• Transmitters and fiber lasers
• Single direction/Bi-direction transmission
• Line monitoring
• FTTX

Specifications (T=23℃)
