Pump laser

Oclaro has expanded its pump portfolio with a new 500mW uncooled 980nm pump laser and a 2 x 600mW dual chip pump in a single package. The pumps are now being sampled by customers and will be available in volume production later this year. The 500mW uncooled pump has an SFF 10-pin butterfly package that can also be used in existing 14-pin slots.

The pump operates across the entire -5 to 75°C temperature range, is wavelength stabilised, qualified to Telcordia GR-468-CORE and is RoHS 6/6 compliant. The 500mW pump is specifically for the SFF single channel and 40Gb/s per-channel amplifiers with higher power requirements. The 600mW dual pump is designed for dual stage and mid-stage access amplifiers, ROADM on blade and amplifier based line cards. It has a 1 x 14-pin package that replaces two discrete pumps. The pump features two dynamically independent co-packaged lasers that are individually addressable and stabilised and offers the full functionality of traditional 14-pin pumps.
