NVIDIA Mellanox MFS1200-E200 200-Meter Active Fiber Cable QSFP28 100Gb/s EDR / 100GbE: This is a 200-meter Active Optical Cable (AOC) with QSFP28 connectors on both ends, supporting InfiniBand EDR (100Gb/s) and 100GbE Ethernet. The cable is a fixed-length integrated assembly with embedded VCSEL optics and an LSZH jacket. It is not a transceiver pair with a detachable patch cord. This is a refurbished unit.
Engineering Context
The MFS1200-E200 is built for cross-data-hall reach where passive copper DACs (limited to roughly 3m at EDR) cannot reach. The 4x 25Gb/s NRZ lane structure delivers an aggregate 100Gb/s line rate. Active optics provide complete EMI immunity and a thin, lightweight cable form factor that places minimal stress on QSFP28 ports. The LSZH jacket reduces toxic emissions during fire events and is mandatory in many modern data centers. Bit error rate (BER) is rated below 1E-15 per the AOC class.
Deployment & Use Cases
Long-reach EDR InfiniBand spine-leaf interconnects in HPC clusters using NVIDIA Switch-IB 2 (SB7800) switches. Cross-row 100GbE Ethernet on Spectrum SN2000 switches. ConnectX-4 / ConnectX-5 EDR / 100GbE host adapter connections to top-of-row switches. Storage fabric uplinks where reach exceeds the limit of passive or active copper.

Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with NVIDIA Switch-IB 2 (SB7800 / SB7890) EDR InfiniBand switches, Spectrum SN2000 series 100GbE Ethernet switches, and ConnectX-4 / ConnectX-5 EDR / 100GbE host adapters. Not compatible with HDR (200Gb/s) or NDR (400Gb/s) ports — those use QSFP56 and OSFP/QSFP-DD form factors respectively. Not a breakout cable; this is point-to-point QSFP28-to-QSFP28 only. Fixed 200m length — connectors cannot be removed or re-terminated.
