## Long description

The BlueOptics CBL-NTWK-0892-OPC20-BL is a 2 m InfiniBand/fibre optic cable with QSFP28 male-to-male connectors designed for high-speed data transfer in data centres and network racks. It supports 100G-class links and is intended for short-reach connections between compatible QSFP28 ports on switches, routers, storage systems and other network equipment. The cable implements a direct attach style connection with a blue jacket and a 2 metre length to bridge adjacent racks or connect components within a single rack while maintaining low latency and compact cabling management.
Advantages
The cable provides a straightforward, passive direct-attach connection with QSFP28 interfaces, enabling reliable 100G data transfer where QSFP28 ports are supported. Its 2 m length offers flexibility for rack-to-rack or in-rack connections without excess slack. The male/male QSFP28 configuration ensures plug-and-play compatibility with hardware that supports QSFP28 direct attach cables. The product is manufactured and tested to meet common MSA and industry quality practices, aiming to deliver consistent electrical performance for Ethernet, Fibre Channel and InfiniBand applications at short distances.
Suitable for
Connecting QSFP28 ports between switches and routers in data centre racks
Short-reach 100G links between storage systems and network devices
Direct attach links inside racks or between adjacent racks

How to use
Ensure both devices support QSFP28 direct attach or compatible 100G ports before connecting. Power down or follow hot-plug guidelines of your hardware vendor if required, then insert each QSFP28 connector firmly into the corresponding port until the latch engages. Route the 2 m cable to avoid sharp bends and excessive tension. Verify link status and negotiated speed in your switch or host interface after connection. If the hardware requires specific firmware or port settings for passive direct attach cables, apply those settings per the device manufacturer instructions.
Usage recommendations
Use this 2 m QSFP28 cable for short-distance, high-bandwidth interconnects where low latency and compact cabling are priorities. Store and handle the cable by the connector housings, avoid bending below manufacturer-specified minimum bend radius and keep the connectors clean to maintain reliable signal integrity.
