InfiniBand/fibre optic cable NVIDIA MCP1650‑H001E30 QSFP56 1 m

NVIDIA MCP1650‑H001E30 QSFP56 1 m is a short‑reach InfiniBand/fibre optic patch cable designed for high‑speed data links in data centers and high‑performance computing environments. The cable provides a direct 200Gb/s connection between QSFP56 ports on switches, adapters and storage systems, offering a low‑latency, high‑bandwidth interconnect for cluster and rack‑level links. The 1 m length is intended for tight rack or chassis connections where a reliable, compact optical or passive direct‑attach solution is required.

Advantages

The cable delivers 200Gb/s throughput using a QSFP56 interface to support demanding data center traffic with reduced latency. As a short‑reach option it provides cost‑effective connectivity for adjacent devices while lowering power consumption and electromagnetic emissions compared with longer active optical solutions. Built and tested to manufacturer production standards, the cable is intended for straightforward installation and consistent out‑of‑the‑box performance and durability.

Suitable for

• Interconnects between servers, switches and adapters within the same rack or adjacent racks
• High‑performance computing clusters requiring low latency and high bandwidth
• Storage systems and NVMe fabrics using QSFP56 ports for short optical or passive connections

Key specifications

• Connector type: QSFP56
• Nominal data rate: up to 200Gb/s
• Cable length: 1 meter
• Form factor: short‑reach patch cable suitable for rack/chassis connections
• Typical use: InfiniBand and compatible high‑speed interconnects

How to use

Install the cable by aligning and inserting the QSFP56 connectors into corresponding QSFP56 ports on the devices until the connector latch engages. Use the 1 m length for connections within the same rack or between adjacent racks to maintain optimal signal integrity and minimize latency. Follow device vendor guidelines for hot‑plugging and ensure ports are free of dust or debris before insertion. For initial setup, verify link training and expected link speed through host or switch management interfaces.

Usage recommendations

For reliable operation, use this 1 m QSFP56 cable in short‑reach topologies and avoid bends below the manufacturer’s minimum bend radius. Keep connectors protected when not in use and confirm compatibility with the host and switch firmware revisions where applicable. In dense deployments, route cables to minimize stress on ports and to reduce electromagnetic interference.
