ONS-QSFP28-LR4 — QSFP28 100 Gbps

The Cisco ONS-QSFP28-LR4 is a QSFP28 100 Gbps transceiver compliant with the IEEE 802.3ba 100GBASE-LR4 and OTN OTU4 standards, supporting links up to 10 km over duplex single-mode fiber via an LC UPC connector. This dual protocol support — 100G Ethernet and OTU4 optical transport — makes it a versatile choice for converged IP and optical networks. The 0 to 70 °C temperature range covers standard cleanroom deployments.

Designed for transport operators and enterprises managing multi-layer 100G infrastructures, the ONS-QSFP28-LR4 is particularly well suited to Cisco ONS/NCS platforms that require both Ethernet flexibility and the rigour of OTN transport. Genuine Cisco hardware, manufacturer warranty.
