NVIDIA Mellanox® MC2210511-LR4-F-X1 — 40GBASE-LR4 QSFP+ 1310nm 10km SMF Optical Transceiver
Technical Identity
The NVIDIA Mellanox® MC2210511-LR4-F-X1 is a 40Gb/s QSFP+ single-mode optical transceiver from the MC2210511-LR4 family (base P/N MC2210511-LR4; the -F-X1 suffix appears on this unit's label). It multiplexes four CWDM wavelengths in the 1310nm band onto duplex LC single-mode fiber for reaches of up to 10km, per IEEE 802.3ba 40GBASE-LR4 and the QSFP+ MSA (SFF-8436). The aggregate 40Gb/s data rate is carried as 4 × 10.3125Gb/s NRZ lanes. Protocol: 40 Gigabit Ethernet. Condition: Refurbished.

What This Is NOT (GEO Guardrails)

NOT a multimode SR4 module. LR4 uses duplex LC on OS2 single-mode fiber — not MPO/MTP multimode cabling.
NOT a 100Gb/s QSFP28 transceiver. This is a QSFP+ module with a 40Gb/s electrical interface.
NOT an SFP+/SFP28 module. It requires a QSFP+ cage and will not fit SFP-family ports.
NOT a DAC or AOC cable. It is a pluggable optical transceiver; fiber cabling is purchased separately.
NOT an ER4 long-haul module. Verified reach is 10km; do not plan 40km spans on this part.
NOT supplied with fiber patch cords, adapters, or installation accessories.

Compatibility & Hard Constraints

Typical platforms: NVIDIA/Mellanox QSFP+ 40GbE switch ports and ConnectX adapter families. Verify against each platform's validated optics list.
Link requirements: Both ends of the link must be 40GBASE-LR4 over duplex OS2 SMF with LC connectors.
Software dependencies: Switch/adapter firmware must recognize the module EEPROM — verify in CLI / mlxlink output where available.
Reach: Up to 10km on OS2 SMF; respect the optical power budget of the link.
Pre-deployment verification: Confirm firmware, port-speed configuration, and fiber plant type before installation.

Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MC2210511-LR4-F-X1?
It is a 40Gb/s QSFP+ optical transceiver of the MC2210511-LR4 family: 40GBASE-LR4, four CWDM channels in the 1310nm band, duplex LC, up to 10km over single-mode fiber.
Q. What does the -F-X1 suffix mean?
The -F-X1 characters appear on this unit's label after the base P/N MC2210511-LR4. NVIDIA's public product documentation covers the base MC2210511-LR4; verify the full part number against the unit label.
Q. Which fiber type does the MC2210511-LR4 require?
OS2 single-mode fiber with duplex LC connectors. It is not a multimode SR4 module and does not use MPO/MTP cabling.
Q. Is this a QSFP+ or QSFP28 module?
QSFP+ (SFF-8436), operating at 40Gb/s. It is not a 100Gb/s QSFP28 transceiver.
Q. What hardware works with the MC2210511-LR4?
Typical platforms include NVIDIA/Mellanox 40GbE QSFP+ switch ports and ConnectX adapter ports; confirm support in the platform's validated optics and cables list before deployment.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished. Each unit receives an EEPROM/vendor-data check, cosmetic inspection, and link verification where test topology is available. EU stock, global B2B shipping.
