Description
The 269-type pump laser module represents a family of thermoelectrically cooled, high-power lasers. They are designed as continuous-wave (CW) optical pump sources for dense wavelength-division multiplexing (DWDM) EDFA applications.

Features
■ High-coupled rated output power up to 280 mW, CW
■ Wide environmental range
■ Field-proven packaging technology
■ InGaAsP/InP high-power, strained multiple quantum-well (MQW) chip design
■ Internal optical isolator (optional)
■ Internal thermoelectric cooler (TEC)
■ InGaAs PIN photodetector back-facet monitor
■ Single-mode and polarization-maintaining fiber pigtails
■ Compact, 14-pin butterfly package
■ Industry compatible package and pinout

Applications
■ Erbium-doped fiber amplifiers (EDFA)
