QSFP-100G-LR4-S — QSFP28 100 Gbps

The Cisco QSFP-100G-LR4-S is a QSFP28 100 Gbps module designed for long-distance links over single-mode fiber (SMF), reaching up to 10 km via LC duplex connector. It complies with the IEEE 100GBASE-LR4 standard, transmitting the signal over four distinct LAN-WDM wavelengths, with an operating temperature range of 0 to 70 °C suited to standard datacenter environments.

Designed for operators and enterprises needing to interconnect buildings or remote server rooms up to 10 km without signal regeneration, the QSFP-100G-LR4-S integrates natively into Cisco QSFP28-compatible chassis. Its 10 km maximum reach makes it the reference choice for metropolitan backbone links. Genuine Cisco hardware, manufacturer warranty.
