COMMUNICATIONS COMPONENTS
Fused Coupler, Single Window, 980 nm
FFCR Series
Key Features
• Ultra low-pump loss
• Minimum wastage of pump power
• High EDFA output power
• Wide range of regular parts readily available
• Proven reliability
Applications
• EDFA pump redundancy and sharing
• EDFA pump monitoring
• Fiber lasers
The 980 nm fused coupler enables the accurate splitting and monitoring of pump
power in erbium-doped fiber amplifiers. In addition, JDSU manufacturing
technology provides uniquely low excess loss, along with low polarization and
temperature dependence for all ports.
These high-performance standard parts are available with a variety of tap ratios
and housing and connector options, and can therefore be specified for a wide
range of applications, enabling rapid design cycles and new project builds.
Standard variants for 960 nm and 1060 nm may also be selected.

1. For wavelength within ±5 nm of the operating wavelength range, the worst-case changes in insertion loss and WDL are shown as follows:
Tap ratio = 1%, maximum insertion loss and WDL increase = 0.65 dB.
Tap ratio = 5%, maximum insertion loss and WDL increase = 0.50 dB.
Tap ratio = 10%, maximum insertion loss and WDL increase = 0.40 dB.
Tap ratio = 50%, maximum insertion loss and WDL increase = 0.20 dB.
