| 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.

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.
