dwdm laser module

dwdm laser module

The 1905 lmi 25mW laser module for dwdm externally modulated operations contains a strained-layer multiple-quantum-well laser chip. Output powers of 20 and 25mW are available as standard options. The itu-t wavelength allocation grid will be offered from 1528 to 1563 nm with 50-GHz spacing. The laser module contains a thermoelectric cooler, precision thermistor, double-stage optical isolator, and a polarization-maintaining pigtail (for use with a LiNbO3 external modulator). Applications include ultralong-haul 2.5- and 10-Gbit/sec dwdm synchronous digital transmission systems, terminals for submarine repeaterless systems, and test equipment.
