STC-CFP2-ER4-LWDM-40KM – 100G CFP2 ER4 40km LWDM Transceiver

Extended-reach 100G CFP2 transceiver with LAN-WDM optics – up to 40km over SMF

Product Overview

The STC-CFP2-ER4-LWDM-40KM is a 100Gbps CFP2 optical transceiver designed for long-haul and metro transport networks. Utilizing four LAN-WDM channels (1295.56nm, 1300.05nm, 1304.58nm, 1309.14nm), the module supports distances up to 40 kilometers over single-mode fiber (SMF) through a standard duplex LC connector. Fully compliant with CFP2 MSA and IEEE 802.3ba 100GBASE-ER4 specifications, it is ideal for high-bandwidth carrier aggregation, core transport, and regional interconnects where signal integrity and reach are critical.
