InfiniBand/fibre optic cable NVIDIA MCP1600‑E003E26 QSFP28 to QSFP28 1 m

NVIDIA MCP1600‑E003E26 QSFP28 to QSFP28 1 m is a high‑speed InfiniBand/fibre optic cable designed for short‑reach connections between QSFP28 ports on switches, host adapters and servers. The 1‑metre optical link provides low latency and reliable high‑bandwidth transmission suitable for data center and high‑performance computing environments where space is limited and signal integrity is critical.

Advantages

This QSFP28 to QSFP28 optical cable delivers consistent, low‑latency connectivity with high bandwidth efficiency for dual‑port QSFP28 systems. Its short, 1 m length reduces signal attenuation and crosstalk risks in dense rack layouts while maintaining stable optical performance. The cable is compatible with standard QSFP28 interfaces and supports InfiniBand and fibre‑optic protocols used in modern data centers.

Suitable for

• Interconnecting QSFP28 ports on switches and leaf/spine architectures
• Linking QSFP28‑equipped host adapters and servers in HPC clusters
• Short‑reach optical connections within racks and between adjacent racks
• Low‑latency, high‑bandwidth data paths for storage and compute nodes

Key specifications

• Connector type: QSFP28 to QSFP28 (optical)
• Length: 1 metre
• Media: fibre optic (short‑reach optical link)
• Target use: InfiniBand and high‑speed fibre‑optic interconnects
• Typical characteristics: low latency, high bandwidth, suitable for dense rack environments

How to use

Install the QSFP28 connectors into matching QSFP28 ports on your switches, adapters or servers until the latch engages. Ensure both endpoints support QSFP28 optical transceivers and configured protocol (InfiniBand or equivalent). Route the cable to avoid tight bends and mechanical stress, keeping bend radius within manufacturer guidelines and avoiding areas with excessive heat or vibration. Verify link status through device management interfaces and confirm link speed and lane configuration after installation.

Recommendations

For optimal performance, use this 1 m QSFP28 optical cable inside racks or between adjacent rack units where short, direct connections are required. Maintain clean connector endfaces, handle the cable by the connector body, and follow your equipment vendor guidance for transceiver compatibility and firmware settings to ensure reliable operation.
