Nvidia MCA4J80-N003-FTF InfiniBand/kuitu-kaapeli 3 m OSFP musta

The Nvidia MCA4J80-N003-FTF is a 3 m InfiniBand/fibre optic cable with OSFP connectors on both ends. It provides up to 800 Gbit/s aggregate throughput and is built with a Low Smoke Zero Halogen (LSZH) jacket in black, offering a compact, high-speed link for data centers and high-performance computing environments.

Advantages

This OSFP to OSFP cable supports very high bandwidth up to 800 Gbit/s and is suitable for short-reach, high-density interconnects. The LSZH jacket reduces toxic smoke in case of fire and the 3 m length allows flexibility in rack or chassis layout. Its design focuses on reliable, low-latency data transmission between switches, servers or adapters that accept OSFP ports.

Suitable for

• Interconnects between servers and switches in data centers
• High-performance computing clusters and AI training nodes
• High-density switch-to-switch connections
• Low-latency storage and compute links

When it may not be suitable

This cable is intended for systems with OSFP ports and for short-reach connections; it is not suitable for long-distance runs or environments that require multimode copper or different connector types. It will not work with equipment that lacks OSFP-compatible interfaces or requires passive copper only if the platform does not support the active optical characteristics.

Key specifications

• Length: 3 m
• Connector type: OSFP on both ends
• Maximum throughput: 800 Gbit/s
• Cable jacket: Low Smoke Zero Halogen (LSZH)
• Color: Black

How to use

Install the cable by aligning and inserting each OSFP connector into the corresponding OSFP port on your network adapter, switch or server until it clicks into place. Route the cable to avoid sharp bends and tension, maintaining manufacturer-recommended bend radius. Verify link status in your host or switch management interface and monitor for expected throughput and error counts during initial operation.

What to consider before purchase

• Confirm that both devices have OSFP ports and support 800 Gbit/s links
• Ensure 3 m length fits your rack or chassis layout and cable routing
• Check that an LSZH jacket meets your facility fire-safety requirements

Recommendations

Use for short, high-bandwidth connections within racks or between adjacent racks. Avoid tight bends and excessive pulling force; monitor link health after installation to confirm expected performance.
