WahE's10G 1577nm directly modulated aser diode is designed for cooled oruncooled applications n 10G PON,including 10G-EPON,XG(S),Combo-PON,POLOLT applications.The Distributed Feedback Bragg grating (DFB)laser is based on the low-cost ridge waveguide designwith AlGalnAs active layers growing on n-type substrate. The laser features low threshold,high output power low power consumption, low chirp low cost and up to 20km transmission distance.

ASRock 10G C/L band long-range DML laser is a distributed feedback based on waveguide structure (DFB) single longitudinal mode-emitting semiconductor laser, which has a unique epitaxial structure design, and the active region adopts the strained multi-quantum well structure of AIGaInAs material. A more efficient design scheme is adopted to further suppress the parasitic tweet caused by direct modulation, which can meet the needs of long-distance transmission applications of ≥ 40km.
