InfiniBand/fibre optic cable MELLANOX MCP1600-E005E26 QSFP28 to QSFP28 5 m Male/Male

The MELLANOX MCP1600-E005E26 is a 5 m InfiniBand/fibre optic cable with QSFP28 connectors on both ends (Male/Male). Designed for high-speed server, switch and storage interconnects, this cable provides a direct QSFP28-to-QSFP28 link suitable for data centre and high-performance computing environments. The cable is intended for short to medium reach links that require QSFP28 connectivity and supports 100Gb/s EDR-class links when used in compatible systems.

Advantages

This QSFP28 to QSFP28 cable offers a compact, single-cable solution for high-bandwidth connections between network devices. It is built to industry-standard QSFP28 electrical interfaces and uses a four-channel 25G NRZ configuration to support aggregate 100Gb/s throughput where supported. Each connector incorporates an EEPROM with product information accessible by the host system, enabling straightforward identification and compatibility checks. The passive design provides a cost-effective, power-efficient option for short-distance interconnects while manufacturing and testing processes aim to ensure consistent performance and durability.

Suitable for

• Direct server-to-switch or switch-to-switch connections in data centres
• High-performance computing (HPC) cluster interconnects
• Storage system links requiring QSFP28 interfaces
• Short to medium reach links within rack or between adjacent racks

Key specifications

• Cable length: 5 metres
• Connector type: QSFP28 male to QSFP28 male
• Typical data rate class: 100 Gb/s EDR (configured as 4×25G NRZ channels where supported)
• Design: passive direct-attach cable for short-distance interconnects
• EEPROM on each connector for product identification and host readout

How to use

Install the cable by aligning each QSFP28 male connector with the corresponding QSFP28 port on the devices to be connected, ensuring the connector latches engage. Confirm that both host systems recognize the EEPROM information and that port settings match the expected data rate and lane configuration. Use the cable within the supported reach for passive DAC/optical operation and avoid routing it through sharp bends or high-heat areas to preserve signal integrity and mechanical life.

Usage recommendations

Use this 5 m QSFP28-to-QSFP28 cable for short to medium intra-rack or adjacent-rack interconnects where 100Gb/s EDR performance and QSFP28 compatibility are required. Verify compatibility with the transceiver and host port firmware, and handle connectors by the housing to avoid stressing the cable or latch mechanism.
