Tecowin Cisco 100GBASE-LR4 QSFP28 Transceiver, LC Duplex, 10km over SMF, 100Gbps, LAN-WDM

Deliver 100 Gbps over single-mode fiber up to 10 km with this Tecowin QSFP28 transceiver, engineered for Cisco compatibility and IEEE 802.3ba 100GBASE-LR4 networks. Four LAN-WDM wavelengths (1295.56nm, 1300.05nm, 1304.58nm, 1309.14nm) multiplex onto a single LC duplex connector, while DDM/DOM support enables real-time monitoring of temperature, voltage, and optical power. Hot-swappable and MSA-compliant, it consumes under 4.5W and operates from 0°C to 70°C.

Overview

The Tecowin QSFP-100G-LR4-S-C is a QSFP28 form-factor optical transceiver for 100 Gigabit Ethernet over single-mode fiber. It complies with the QSFP28 MSA and IEEE 802.3ba 100GBASE-LR4 standard, ensuring interoperability with Cisco switches, routers, and other MSA-compliant devices. The module uses a duplex LC connector and supports hot-swapping for minimal network downtime.
