The fused coupler, low loss, C+L band or S band enables the accurate splitting and
monitoring of optical signals in single-mode fiber. In addition, JDSU
manufacturing technology provides uniquely low excess loss and wavelength
dependence, along with low polarization and temperature dependence for both
signal and tap ports.
These high-performance standard parts are available in a variety of tap ratios,
operating wavelengths, and housing and connector options, and can therefore be
specified in a wide range of applications, enabling rapid design cycles and new
project builds.

1. Tap ratio five percent, the Insertion Loss including WDL, PDL and TDL; Tap ratio > five percent, the Insertion Loss including WDL and PDL, not including TDL.
2. In 2x2 couplers with a coupling ratio of 20 percent or lower, insertion loss is not specified for launch through second input port (P4).
3. Change in insertion loss over the operating wavelength range.
4. Change in insertion loss over all input polarization states.
5. Change in insertion loss from –5 to 75°C.
