Product information

Description

The BlueOptics CBL-NTWK-0942-MQ28C30M-BL is a 3 m InfiniBand / fibre optic cable with QSFP28 male-to-male connectors designed for short-range, high-speed links in rack and adjacent-rack installations. It supports 100G data rates and is suitable for direct-attach connections where reliable electrical or optical connectivity is required between switches, storage systems, routers and high-performance computing nodes. The cable follows industry MSA guidelines and is intended for environments that demand low latency and consistent signal integrity.

Advantages

This 3 m QSFP28 cable delivers up to 100G throughput with low latency and minimal power consumption typical of passive direct-attach twinax solutions. It is produced using selected high-quality components to ensure robust electrical performance and durability for continuous operation. The compact QSFP28-to-QSFP28 design simplifies cabling in dense rack environments and reduces the need for transceivers when used as a direct attach solution.

Suitable for

  • 100G direct attach links between switches and routers in data centers
  • Interconnects between servers and top-of-rack or adjacent-rack switches
  • High-performance computing clusters using InfiniBand or Ethernet fabrics
  • Storage systems and SAN connectivity supporting 100G signalling

Key specifications

  • Cable length: 3 metres
  • Connector type: QSFP28 male to QSFP28 male
  • Maximum data rate: up to 100 Gbit/s
  • Cable type: passive direct attach twinax (suitable for short distances)
  • Conductor gauge: 26 AWG
  • Standards: MSA-compliant QSFP28 electrical / InfiniBand and 100GBase-CR4 compatible signalling
  • Typical power consumption: passive (low power, ~0.1 W for comparable cables depending on host)

How to use

Install the QSFP28 connectors into compatible QSFP28 ports on each device until the latch engages. Verify that both connected devices support passive DAC cables and the 100G signalling protocol in use (Ethernet, FCoE, Fibre Channel or InfiniBand). Use the 3 m length to connect hardware within the same rack or to adjacent racks; avoid tight bends and excessive pulling force. After physical installation, check link status and negotiate network settings on the connected devices according to the vendor documentation.

Usage recommendations

For reliable operation, confirm compatibility with your switch or server vendor and ensure QSFP28 ports are configured for passive DAC operation. Route the cable to avoid sharp bends (maintain manufacturer minimum bend radius), secure it to prevent strain on connectors, and operate within recommended temperature and humidity ranges for your equipment. For critical installations consider testing a sample cable in your environment before large-scale deployment.
