QSFP28 100G 1310nm 40km LC Optical Transceiver for Long-Distance SMF
Product Overview
The QSFP28 100G 1310 40km SM is a high-speed long-reach optical transceiver designed for 100 Gigabit Ethernet applications over single mode fiber. Operating at a 1310 nm wavelength with CWDM multiplexing, it delivers 100 Gbps through four parallel 25 Gbps channels. This module supports transmission distances of up to 40 kilometers and is ideal for telecom backbone, metro access, and long-distance data center interconnect applications. It features an LC duplex connector and complies with IEEE 802.3ba and 100GBASE-ER4 Lite standards.
