Product description

A two-channel WDM that simultaneously splits or couples a pair of wavelengths for combinations of O/L, O/C, or O/U bands. This coupler provides low loss over a wide range of temperatures and has low polarization dependence. O/C band or O/L band components are used to double network bandwidth whilst the O/U band component is used to add or drop a supervisory wavelength from a system.

G&H’s proprietary manufacturing technology provides uniquely low excess loss and wavelength dependence along with low polarization and temperature dependence for all ports. In addition to the standard wavelengths shown, other combinations such as S/L band are available. Please contact us for more information.
