COMMUNICATIONS COMPONENTS
Attenuator, Fused Fiber
Key Features
• Environmentally stable
• High performance
• Broadband coverage
• Compact size
• Custom parts available
Applications
• Power management in optical networks
• Wavelength division multiplexing
(WDM) system channel balancing
• Receiver protection
• Test equipment
The JDSU fused fiber attenuator is a compact, fused component that decreases
optical power in telecommunications equipment, passive telephony, or cable
television (CATV) networks and test equipment.
JDSU proprietary manufacturing technology provides high performance parts
that are optimized to the required operating wavelength, narrowband, or
broadband - along with low polarization and temperature dependence.
Regular parts are available in a wide variety of operating wavelengths, tap ratios,
fiber types, housing and connector options. Our extensive selection enables rapid
design cycles and new project builds.
