DD-AA-310-001
DD-AA-310-001 is a 1310 nm single mode edge-emitting laser diode chip for uncooled applications up to 3.2 Gb/s. This distributed-feedback (DFB) laser is based on ridge-waveguide structure with multiple quantum well (MQW) design. This laser features high optical power output, high SMSR, wide working temperature range and small far field angle.
Low threshold current
Modulation rate up to 3.2 Gbps
Operating temperature range -40 to 85°C
Complied with Telcordia GR-468
