LP-E1550-10-C-Dxx is a Distribute Feedback (DFB) edge-emitting laser diode chip integrated with Electro-absorption Modulator (EAM) which provide a single longitudinal mode at DWDM wavelength and use in cooled applications up to 10 Gb/s. The chip structure is waveguide stripe, including multiple quantum wells (MQWs) active layers for low dispersion penalty and high extinction ratio design. All EA-LD chips come from wafers that have been certified using a representative lot of devices that must achieve an acceptable yield for CW, dynamic and ESD tests.
