描述 Description

The 269-type DFB pump laser module represents a family of thermoelectrically cooled, high-power lasers. These devices achieve stable wavelength performance within the 1420 nm to 1510 nm range, over the full operating temperature range. They are designed as continuous-wave (CW) optical pump sources for dense wavelength-division multiplexing (DWDM) EDFA and Raman applications operating in the C- and L-bands.
