The series 980nm pump module utilizes a planar construction with chip on subcarrier. The high power chip is hermetically sealed in a epoxy-free and flux-free 14-pin butterfly package and fitted with a thermistor, thermoelectric cooler, and monitor diode.
The series pump module uses FBG stabilization to ”lock” the emission wavelength. It provides a noise-free narrowband spectrum, even under changes in temperature, drive current, and optical feedback. Wavelength selection is available for applications that require the highest performance in spectrum control with the highest available powers. This module complies described in Telcordia GR-468-CORE requirement.

Notes:
[1] Kink Current is defined as the current which deviation of light versus current slop(dL/dI)from a linear fit is beyond +/-50%,Pkink>=1.2*Rated Power,Ikink>=If(BOL)*1.2
[2] Tracking error is defined at a given case temperature,it is the change in fibre power,at a constant monitor current, relative to the value measured at case 25℃
