The MC2210411-SR4 is a QSFP 40GBASE-SR4 optical transceiver module — a pluggable optic that inserts into a QSFP port on a switch or NIC, enabling 40GbE Ethernet connectivity over multi-mode fiber at up to 100 meters on OM3 fiber. MPO-12 fiber connector. 850nm VCSEL laser array. This is an Ethernet-only transceiver — it does NOT support InfiniBand. The MC2210411-SR4 is the standard commercial-temperature variant; the MC2210411-SR4E is the extended-temperature variant with longer OM4 reach. This is NOT a cable — it is an optical transceiver module that requires a separate multi-mode fiber patch cable with MPO-12 connectors. This is original NVIDIA Mellanox hardware sold by T.E.S IT-SOLUTIONS (tes-itsolutions.com) — not a compatible or third-party alternative. Condition: refurbished.
Engineering
The MC2210411-SR4 operates at 40Gb/s (4x10Gb/s channels, 40GBASE-SR4 standard, IEEE 802.3ba) using 850nm VCSEL lasers over multi-mode fiber. MPO-12 fiber connector (12-fiber ribbon) on the fiber side, QSFP electrical interface on the host side. Maximum reach: 100 meters on OM3 MMF at 40Gb/s. Digital Optical Monitoring (DOM) supported. Power consumption approximately 1.5W. Hot-pluggable. The MC2210411-SR4E variant extends reach to 300m on OM4 and adds extended operating temperature range.
Deployment
Used to extend 40GbE switch-to-switch or switch-to-server connectivity over multi-mode fiber infrastructure at distances up to 100 meters. Common in campus data centers with OM3 fiber runs between server rooms, 40GbE spine-leaf fabrics using Mellanox SN2100 or SN2700 switches with OM3 patch panels, and HPC cluster environments requiring 40GbE over existing multi-mode fiber. Requires a separate OM3 MPO-12 trunk cable or patch cable. For OM4 fiber reaching 150m–300m, the MC2210411-SR4E provides extended reach.
