NVIDIA Mellanox MFS1S50-V005E Active Fiber Splitter Cable, 200Gb/s to 2x 100Gb/s, QSFP56, 5m, LSZH: This enterprise networking cable is a 5-meter active optical splitter cable that breaks out a single 200Gb/s QSFP56 port into two independent 100Gb/s QSFP56 connections, part number MFS1S50-V005E (NVIDIA P/N 980-9I96R-00V005). The cable uses active fiber optics and LSZH (Low Smoke Zero Halogen) jacket material. This is a refurbished unit, tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MFS1S50-V005E enables breakout from a single 200Gb/s port to two 100Gb/s links using PAM4 signaling at 50 Gb/s per lane (2 lanes per 100Gb/s link). As an active optical cable, it contains laser transceivers at each end, requiring power from the QSFP56 ports (typically 3.5W per connector). The active design supports longer distances than passive copper while maintaining signal integrity. The LSZH jacket meets datacenter fire safety requirements (IEC 60332-1). At 5 meters, this cable supports intra-rack and short inter-rack connections.
Deployment & Use Cases
HDR InfiniBand or 200GbE fabric breakout connecting a single 200Gb/s switch port to two 100Gb/s host channel adapters or NICs. Maximizing port utilization on HDR switches in HPC and AI training clusters running NCCL or MPI. ConnectX-6 HDR100 adapter connectivity from HDR switches. Datacenter environments requiring LSZH-rated cabling for fire safety compliance.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MFS1S50-V005E
NVIDIA P/N: 980-9I96R-00V005
Type: Active Fiber Splitter Cable (AOC Breakout)
Data Rate: 200Gb/s to 2x 100Gb/s
Lane Rate: 50 Gb/s per lane (PAM4)
Connectors: 1x QSFP56 to 2x QSFP56
Length: 5 meters
Cable Type: Active Optical (multimode fiber)
Jacket: LSZH (Low Smoke Zero Halogen)
Power: Requires power from QSFP56 ports (~3.5W per end)
Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
QSFP56 Ports Required: All three connectors are QSFP56. Not compatible with QSFP28, QSFP-DD, OSFP, or SFP ports. Active Cable: Requires power from the host QSFP56 port. Will not function in unpowered cage slots. Splitter Cable: This is a 1-to-2 breakout (200Gb/s → 2x 100Gb/s). The switch port must support breakout mode. This is NOT a 1-to-2 splitter at 200Gb/s on each leg — it splits 200Gb/s into two 100Gb/s links. HDR Speed Tier: Designed for HDR/HDR100. Not backward-compatible with EDR or FDR at native speeds. Shorter option: MFS1S50-V003E (3m). Longer option: MFS1S50-V010E (10m) if available.
