COMMUNICATIONS MODULES & SUBSYSTEMS
Coarse Wavelength Division Multiplexer/Demultiplexer
(CWDM) Filter
Key Features
• Low insertion loss
• Low polarization dependent loss
• Extended operating temperature range suitable for
uncontrolled environment
• Exceptional reliability and environmental stability
• Excellent temperature stability
Applications
• Metro optical networks
• Access optical networks
• Enterprise networks
The JDSU CWDM modules, based on thin-film filter (TFF) technology, provide
extremely high performance. With low insertion loss, low polarization
sensitivity, and high temperature stability, these modules are well suited to
CWDM network applications. The modules can mux/demux 4 or 8 CWDM
channels in the network.
These fixed CWDM modules offer low-cost wavelength management solutions. In
addition, they are easily customizable, and can be configured by customer-specific
channel plan, packaging type, and connector type.
