Product description

Designed for space-constrained optical amplifiers, this WDM is manufactured using ø80 um cladding fiber, enabling low fiber bend radius within modules without compromising mechanical integrity.

G&H’s proprietary manufacturing technology provides uniquely low insertion loss for signal and pump paths, which promotes low noise and the efficient use of pump power in optical amplifiers. Standard wavelengths of operation are based on 980 nm pumping and C, L, or C+L signal bands, and reliability is assured through qualification to Telcordia GR-1221. Other wavelength combinations are available for diverse requirements such as sensing, fiber lasers, and fiber-optic gyroscopes. Please contact us with your specific requirements.
