## Summary description

The BlueOptics CBL-NTWK-0892-OPC30-BL is a 3 m InfiniBand/fibre optic cable featuring QSFP28 connectors. It is designed for high-speed data transmission and reliable connectivity in data centers and networking environments. The male/male configuration ensures compatibility with various devices, making it an essential component for modern networking solutions.

## Long description

The BlueOptics CBL-NTWK-0892-OPC30-BL InfiniBand/fibre optic cable is a 3 m QSFP28 Male/Male link designed for high-speed data transmission in racks and adjacent rack connections. It supports 100G applications including Ethernet, FCoE, Fibre Channel and InfiniBand on short distances and is intended for use with hardware that accepts QSFP28 direct-attach connections. The cable uses a twinax copper/passive design compatible with MSA QSFP28 interfaces and is suitable for data centre top-of-rack and adjacent-rack interconnects where low latency, low power consumption and reliable 100G links are required.
Advantages
This 3 m QSFP28 Male/Male cable provides a direct-attach solution for 100GBase-CR4 connections with low latency and minimal power draw. Manufactured to MSA-compliant specifications, it offers interoperability with major hardware platforms that support QSFP28 direct attach cables. The passive twinax construction reduces complexity and failure points while delivering predictable electrical performance at short distances. High-quality components and testing ensure consistent functionality and long service life suitable for professional networking environments.
Suitable for
 Top-of-rack and adjacent-rack switch interconnects
 High-density server-to-switch links in data centres
 Storage array connections supporting 100G protocols
 InfiniBand clusters and high-performance computing interconnects
 Short-reach 100G Ethernet, FCoE and Fibre Channel links
Key specifications
 Cable length: 3 meters
 Connector type: QSFP28 Male to QSFP28 Male
 Supported data rate: up to 100 Gbit/s
 Application: 100GBase-CR4, Ethernet, FCoE, Fibre Channel, InfiniBand
 Cable type: passive twinax/direct attach copper
 Wire gauge: 26 AWG
 MSA-compliant QSFP28 electrical interface
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on your network devices until the latch engages. Use the cable for short-distance connections within racks or between adjacent racks, observing the 3 m maximum distance for guaranteed 100G performance. Ensure the connected devices support passive DAC twinax QSFP28 modules and the intended protocols (Ethernet, FCoE, Fibre Channel or InfiniBand). Handle the cable by the connector housings and avoid sharp bends; maintain the recommended bend radius to preserve signal integrity.
Usage recommendations
Verify device compatibility with QSFP28 passive direct-attach cables before deployment. Route the cable to minimize stress and interference from power cables, and perform link testing after installation to confirm 100G operation. For installations requiring longer reach or optical isolation, consider active optical cables or transceiver-plus-fibre solutions instead of passive twinax DACs.
