COMMUNICATIONS COMPONENTS
Fused Coupler, Single Window
Key Features
• Wide wavelength coverage over multiple bands
• 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 single window fused coupler splits or combines light with high performance
over a wide bandwidth. These components are manufactured with a highly
automated process to achieve consistent quality and reliability.
Regular parts are available with a wide variety of tap ratios, operating
wavelengths, 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.
