10G CWDM (1271~1371nm) DFB Chip
10G CWDM 1271-1371nm 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. They are primarily used in Ethernet and 4G/5G wireless fronthaul access networks.
