2.5G 1490nm DFB chip
2.5G 1490nm DFB semiconductor laser chips utilize AlGaInAs materials, a multi-quantum well structure, and a ridge waveguide process. These single-mode edge-emitting laser chips feature low threshold, high bandwidth, and wide operating temperature, and are primarily used in GPON OLT and point-to-point applications.
