COMMUNICATIONS COMPONENTS
Fused Coupler, Two Window
Key Features
• Provides 1310 nm and 1550 nm wavelength coverage
• Broadband operation ±40 nm
• High power handling
• Wide range of regular parts available "to go"
• Proven reliability
Applications
• Passive optical networks
• CATV
• Network expansion
• Fixed attenuation (select
configuration option 0)
The two window fused coupler splits or combines light with high performance
over two wavelength regions, maintaining a broad bandwidth in both. This
component is manufactured with a highly automated process to achieve
consistent quality and reliability.
Regular parts are available with a wide variety of tap ratios, housing and
connector options and can therefore be readily specified in a wide variety of
applications, enabling rapid design cycles and new project builds. Reliability is
assured through qualification to Telcordia GR-1221.
