## Summary description

The BlueOptics CBL-NTWK-0892-OPC05-BL is a 0.5 m InfiniBand/fibre optic cable featuring QSFP28 connectors. It provides high-speed data transfer and is designed for reliable connectivity in data centers and high-performance computing environments.

## Long description

The BlueOptics CBL-NTWK-0892-OPC05-BL is a 0.5 m InfiniBand/fibre optic cable with QSFP28 male-to-male connectors designed for short-range, high-speed interconnects in data centers and high-performance computing environments. This cable supports 100GBase-CR4 and is suitable for direct attach or short-distance electrical connections where QSFP28 interfaces are supported. The 0.5 m length and QSFP28 form factor make it suitable for rack-to-rack or adjacent-rack links, server-to-switch connections and other scenarios requiring compact, low-latency connectivity.
Advantages
The cable delivers high data throughput up to 100 Gbps over a 0.5 m link while maintaining low latency and low power consumption typical of passive direct attach twinax solutions. It is built to MSA-compliant QSFP28 specifications to ensure compatibility with major hardware platforms that support QSFP28 and 100GBase-CR4. The compact design and proven component selection provide durable operation and stable signal integrity for short-distance links in dense rack environments.
Suitable for
Short-range 100 Gbps server-to-switch or switch-to-switch connections within racks
High-performance computing clusters requiring InfiniBand or Ethernet 100G interconnects
Storage systems and SAN links using QSFP28 interfaces
Data center deployments where low latency and low power are priorities
Key specifications
Connector type: QSFP28 male to QSFP28 male
Length: 0.5 m
Supported protocols: 100GBase-CR4, Ethernet, FCoE, Fibre Channel, InfiniBand (up to 100 Gbps)
Cable type: passive twinax/direct attach (electrical signaling for short distances)
Wire gauge: 30 AWG
Compliance: MSA-compliant QSFP28 form factor
How to use
Before installation, verify that both devices support QSFP28 passive direct attach twinax cables and the required 100GBase-CR4 or InfiniBand protocol. Power down or follow hot-plug guidelines for your equipment if recommended by the hardware vendor. Align each QSFP28 connector with the corresponding port and insert until it latches; ensure secure seating. Route the 0.5 m cable to avoid sharp bends and mechanical strain on the connectors. After connection, confirm link status through the host or switch management interface and verify negotiated speed and link health.
Usage recommendations
Use this 0.5 m QSFP28 direct attach cable for short, high-bandwidth interconnects inside racks or between adjacent racks. Avoid exceeding recommended bend radius and keep the cable free from crushing or heavy cable tie stress. For longer links or fiber-based routing between distant racks, select optical QSFP28 transceivers and appropriate fiber cabling instead.
