3CN00520AM

3CN00520AM is a 980 nm pump laser which is intended to be used in erbium doped fiber amplifiers, EDFAs, in submerged repeaters and active branching units. The module contains a heterojunction multi-quantum well Fabry-Perot laser. To provide wavelength stabilization, a low reflectivity Fiber Bragg Grating (FBG) is integrated in a Polarization Maintaining Fiber (PMF) pigtail. The pump module is provided in an uncooled 14-pin butterfly package with a backfacet monitor photodiode. Burnin and ageing processes for the laser chip and module are in accordance with submarine system requirements. 3CN00520AM is typically used in 980 nm high power pumping of submerged Erbium Doped Fiber Amplifiers for WDM repeaters and branching units.
