Why use an AOC instead of transceivers with patch cords for 15m?

For 15m runs, AOCs are generally more cost-effective and easier to install than purchasing separate SR4 transceivers and MPO patch cords. AOCs are factory-terminated and tested, eliminating dirty fiber end-face issues.

Does the MFA1A00-C015 support 4x25G breakout mode?

No. The MFA1A00-C015 is a direct QSFP28-to-QSFP28 cable for 1:1 100GbE connections. For 4x25G breakout, a specialized breakout AOC (QSFP28 to 4xSFP28) is required.

What does the LSZH jacket mean?

LSZH (Low Smoke Zero Halogen) means the cable jacket emits minimal smoke and no toxic halogens when exposed to heat or fire. This is mandatory in many modern data centers for personnel safety and equipment protection.

NVIDIA Mellanox MFA1A00-C015 100GbE QSFP28 Active Optical Cable, 15m LSZH: This is a 15-meter active optical cable (AOC) engineered for 100Gb/s Ethernet (100GbE) point-to-point interconnectivity. The cable uses VCSEL optics over multi-mode fiber with a Low Smoke Zero Halogen (LSZH) jacket for data centers with strict fire safety requirements. This is a fixed-length integrated assembly, not a transceiver with a detachable patch cord. This is a refurbished unit.

Engineering Context

The MFA1A00-C015 is designed for middle-of-row and end-of-row Ethernet topologies where passive copper cannot reach. At 15 meters, it bridges the gap between Top-of-Rack switches and aggregation layers. The cable is lightweight and puts negligible stress on switch ports compared to copper bundles. It provides 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

Cross-row 100GbE connectivity between racks in a data hall. Connecting GPU compute nodes to storage appliances over longer spans. Spine-leaf Ethernet interconnects where reach exceeds 5m. Deployments in data centers with strict LSZH cable requirements or limited cable tray weight capacity.
