Its male-to-male configuration allows for easy installation and compatibility with various devices.

## Long description

The BlueOptics CBL-NTWK-0942-MQ28C15M-BL is a 2 m InfiniBand/fibre optic cable with QSFP28 male connectors on both ends. Designed for short-reach, high-bandwidth interconnects, this cable supports 100G data rates and is intended for use in racks and adjacent-rack connections. The cable follows industry MSA guidelines for QSFP28 direct attach twinax solutions and provides a compact, low-latency link between compatible QSFP28 ports.
Advantages
This 2 m QSFP28 male-to-male cable offers a passive direct-attach twinax design with 30 AWG conductors, yielding low power consumption and minimal latency for short-distance connections. Built to meet MSA-compliant physical specifications, it provides straightforward plug-and-play installation and is compatible with major hardware platforms that accept QSFP28 100GBase-CR4 connections. Component selection from established manufacturers contributes to a stable operational lifetime and predictable performance in rack environments.
Suitable for
Short-reach server-to-switch and switch-to-switch connections within racks or between adjacent racks
High-performance computing (HPC) and InfiniBand interconnects requiring 100G links
Data center fabrics, storage systems and 100G Ethernet or Fibre Channel deployments over short distances
Key specifications
Length: 2 meters
Connector type: QSFP28 male to QSFP28 male
Supported data rate: up to 100 Gbps
Cable type: passive direct attach twinax (copper) with 30 AWG conductors
Form factor: QSFP28 MSA-compliant
Typical power consumption: very low (passive cable, estimated around 0.1 W system-level impact)
How to use
Install the cable by inserting each QSFP28 connector firmly into the corresponding QSFP28 port on the two devices to be connected, ensuring proper alignment of the latch mechanism. Verify that the connected devices support passive 100GBase-CR4 or compatible QSFP28 direct attach twinax connections in their firmware or hardware compatibility lists. After physical connection, confirm link status and negotiated speed through the device management interface or monitoring tools. For best results, avoid sharp bends and keep the cable routed to prevent mechanical stress.
Usage recommendations
Use this cable for short-distance 100G links within racks and adjacent racks where passive QSFP28 direct attach twinax is supported. Avoid using passive twinax cables for longer runs beyond the recommended short-reach distances; for longer links, consider active copper or optical transceivers and appropriate fibre optic cabling. Regularly inspect connector contacts and latches for debris or damage and follow vendor compatibility guidance to ensure uninterrupted operation.
