1 / 8 page 269-Type 1480 nm Pump Laser Module Data Sheet June 2001 The 269-type pump laser module is designed as a continuous- wave (CW) optical pump source for erbium-doped fiber ampli- fiers. Features s High-coupled rated output power up to 280 mW, CW s Wide environmental range s Field-proven packaging technology s InGaAsP/InP high-power, strained multiple quan- tum-well (MQW) chip design s Internal optical isolator (optional) s Internal thermoelectric cooler (TEC) s InGaAs PIN photodetector back-facet monitor s Single-mode and polarization-maintaining fiber pig- tails s Compact, 14-pin butterfly package s Industry compatible package and pinout Applications s Erbium-doped fiber amplifiers (EDFA) 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. The laser modules incorporate a high-power, quan- tum-well laser chip that achieves fiber powers up to 280 mW. An integral thermoelectric cooler (TEC) stabilizes the laser at room temperature and, combined with a her- metic environment, allows the device to achieve high-power operation over the extended temperature range of 0 °C to 75 °C. An internal InGaAs PIN pho- todiode, mounted behind the laser diode, functions as the laser detector and monitors light emissions from the rear facet of the laser. The 269-type module is offered in a 14-pin, hermetic butterfly package. |
