NVIDIA Mellanox MFA1A00-C005 100GbE QSFP28 Active Optical Cable, 5m LSZH — Lot of 4 (New): This is a multipack of four 5-meter active optical cables (AOC) engineered for 100Gb/s Ethernet (100GbE) point-to-point interconnectivity. Each cable uses VCSEL optics over multi-mode fiber with a Low Smoke Zero Halogen (LSZH) jacket for data centers with strict fire safety requirements. These are fixed-length integrated assemblies, not transceivers with detachable patch cords, and not a single 4-leg breakout. This listing is for 4 new units shipped together.
Engineering Context
Each MFA1A00-C005 is sized for intra-rack and short cross-rack 100GbE links. At 5 meters, the cables cover ToR-to-server and adjacent-rack runs where passive copper bulk and weight start becoming impractical. AOCs are lightweight and put negligible stress on switch ports compared to copper bundles. They provide complete EMI immunity, essential when routing near power distribution units. The LSZH jacket ensures compliance with strict data center fire safety codes. BER is rated at less than 1E-15.
Deployment & Use Cases
Bulk top-of-rack 100GbE switch to server NIC connectivity. Multi-host ConnectX-4/5/6 deployments to Spectrum SN2000/SN3000/SN4000 switches. Spare-cable allocation across multiple racks in a single procurement. New-build aisle deployments where LSZH is mandated.
