NVIDIA Mellanox MFA1A00-E030 InfiniBand EDR Active Optical Cable, 30m LSZH: This is a 30-meter active optical cable (AOC) engineered for InfiniBand EDR (Enhanced Data Rate) point-to-point interconnectivity at 100Gb/s. The cable uses VCSEL optics over multi-mode fiber with a Low Smoke Zero Halogen (LSZH) jacket. This is a fixed-length integrated assembly, not a transceiver with a detachable patch cord. This is a refurbished unit.
Engineering Context
The MFA1A00-E030 implements EDR signaling at 4x 25Gb/s NRZ across each lane group for an aggregate 100Gb/s rate. At 30 meters, it spans cross-row distances where DAC copper is impractical due to weight, bend radius, and EMI exposure. The integrated VCSEL transceivers are factory-matched for low BER and require no field tuning. The LSZH jacket emits minimal smoke and no halogenated gases under thermal stress, satisfying common data center fire safety codes. AOC weight is a fraction of equivalent copper, reducing strain on switch ports and cable trays.
Deployment & Use Cases
HPC compute fabrics linking ConnectX-4 / ConnectX-5 EDR HCAs to Switch-IB 2 (SB7800 series) leaf or spine switches across rack rows. AI training clusters where 30m EDR uplinks bridge GPU compute aisles to storage aggregation. Storage Area Networks running NVMe-oF over RDMA. Long-reach EDR runs in data halls with strict LSZH cable jacket requirements.

Compatibility & Hard Constraints
Compatible with NVIDIA Switch-IB 2 (SB7800 series) and ConnectX-4 / ConnectX-5 VPI host channel adapters in EDR mode. Requires QSFP28 ports configured for InfiniBand EDR signaling. Not compatible with 100GbE Ethernet ports unless the host platform supports VPI mode reconfiguration to InfiniBand. Not compatible with QSFP+ FDR or QSFP56 HDR ports (link rate mismatch). This is a direct QSFP28-to-QSFP28 cable; does not support breakout. Fixed 30m length.
