The 1999PLM is a new generation of 980 nm terrestrial pump modules powered by an in-house chip technology. Low Profile, 14-pin butterfly modules are available with an operating power up to 330mW. They incorporate a thermoelectric cooler (TEC), a precision NTC thermistor and a back-facet monitoring photodiode. The wavelength is “locked” utilizing a fiber Bragg grating (FBG) located in a Single Mode HI1060 Fiber (SMF) pigtail. The module meets TelcordiaTM GR-468-Core requirements for hermetic 980nm pump modules.

The following parameters are specified BOL for a Tsubmount = 25 °C, Tcase = -5 °C to 75 °C, VBFM = -5 V and -50 dB max back-reflection unless otherwise stated.

(1) Ith is the intersection point with the x-axis of a linear fit of the P(I) curve between 15 mW and 50 mW
(2) A kink is detected when the local slope dP/dI is below Smin or above Smax. Smin is defined as 0.5xSavg and Smax is defined as 1.5xSavg
(3) EOL forward current I(EOL)= 1.1x I(BOL)
(4) Pband is defined as the power within the band p ±1.5 nm vs the total output power
