The JDSU fused coupler, 980 nm, enables the accurate splitting and monitoring of pump power in erbium doped fiber amplifiers. JDSU proprietary manufacturing technology provides uniquely low excess loss, along with low polarization and temperature dependence for all ports. These high performance regular parts are available in 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. Standard variants for 960 nm and 1060 nm may also be selected. Reliability is assured through qualification to Telcordia GR-1221, with a field proven FIT rate of <1. * Minimum wastage of pump power * Wide range of regular parts available * EDFA pump redundancy and sharing |
