Note: 1. TC = 40; Life time of the HL1553 is determined under the conditions at TC = 40, PO = 1.5 mW (VR(EA) = 0).
The HL1553 is a 1.55 m InGaAsP distributed-feedback laser diode (DFB-LD) with a multi-quantum well (MQW) structure. An electroabsorption (EA) modulator is integrated with the laser diode. It is suitable as a light source for high-bit-rate, long haul fiberoptic communication systems, such as 2.5 Gbps external modulation systems.
