NVIDIA Mellanox MC2210511-LR4 QSFP+ Optical Transceiver, 40GbE / FDR10 InfiniBand, 1310nm LR4, 10km: This is a QSFP+ pluggable optical transceiver module engineered for long-reach 40Gb/s Ethernet (40GbE) and FDR10 InfiniBand connectivity over single-mode fiber. The module uses LR4 (Long Reach 4-lane) CWDM optics in the 1310nm wavelength region, multiplexing four CWDM channels onto a single duplex SMF pair. This is NOT an SR4 short-reach module and NOT a multi-mode (MMF) optic. Condition: New.
Engineering Context: The transceiver supports a maximum reach of up to 10km over duplex single-mode fiber (G.652) using a duplex LC connector. It carries 40Gb/s aggregate bandwidth as 4 lanes × 10Gb/s NRZ, multiplexed via CWDM around 1271/1291/1311/1331nm. The QSFP+ form factor is hot-pluggable and consumes typical power within the QSFP+ envelope. The module supports both 40GbE Ethernet and FDR10 InfiniBand protocol modes when paired with a Mellanox VPI host.
Deployment & Use Cases: Used for inter-rack and inter-building 40GbE and FDR10 InfiniBand uplinks where reach exceeds the 100–150m capability of QSFP+ SR4 (MMF) optics. Common in HPC clusters spanning multiple data center halls, campus backbone aggregation, and storage replication links between buildings. Suited to ConnectX-3 / ConnectX-3 Pro adapters and SwitchX / SwitchX-2 switches operating in 40GbE or VPI mode.
Technical Specifications:
Form factor: QSFP+ (hot-pluggable)
Data rate: 40GbE Ethernet and FDR10 InfiniBand (40Gb/s aggregate, 4×10Gb/s NRZ)
Optical interface: LR4 CWDM, 1310nm region, duplex LC connector
Fiber type: Single-mode fiber (SMF, G.652)
Maximum reach: up to 10km
Modulation: NRZ, 4 CWDM lanes multiplexed onto one duplex SMF pair
Protocol modes: 40GbE Ethernet, FDR10 InfiniBand
Condition: New
Compatibility & Constraints: Compatible with Mellanox QSFP+ host ports on ConnectX-3 / ConnectX-3 Pro adapters and SwitchX / SwitchX-2 switches. Requires duplex single-mode fiber and an LC-LC patch cord; multi-mode fiber is NOT supported. This module is for QSFP+ at 40Gb/s; it is NOT a QSFP28 100GbE optic and is NOT compatible with 100GbE QSFP28 host ports. Vendor lock-in or DDM compliance on third-party non-Mellanox switches is not guaranteed.
