## Summary description

The BlueOptics CBL-NTWK-0892-OPC15-BL is a 2m InfiniBand/fibre optic cable featuring QSFP28 connectors. It is designed for high-speed data transmission in data centers and networking environments. The male/male connectors ensure a secure connection, making it ideal for connecting switches, routers, and servers. This cable offers reliable performance and durability for demanding applications.

## Long description

The BlueOptics CBL-NTWK-0892-OPC15-BL is a 2-meter high-speed QSFP28 to QSFP28 cable designed for short-reach interconnects in data centers and network racks. Compatible with InfiniBand and Ethernet 100GBase-CR4 applications, this male-to-male cable supports direct attach twinax copper connections where QSFP28 interfaces are required. The cable is intended for linking switches, routers, servers and storage systems that support passive 100G Direct Attach Cable (DAC) connections and provides a reliable physical layer for demanding networking tasks.
Advantages
The cable offers a compact and low-latency connection method for short-distance links, with passive twinax construction that minimizes power consumption and reduces points of failure compared with active optics. Designed to meet common MSA electrical and mechanical requirements for QSFP28 DACs, it provides consistent performance for 100 Gbps signaling over 2 meters and is built from industry-standard components to ensure compatibility and durability in rack-to-rack and within-rack installations.
Suitable for
 Connecting QSFP28 ports between switches and routers for 100G uplinks
 Direct server-to-switch or server-to-storage connections in racks
 InfiniBand links and high-performance computing interconnects with 100G support
 Short-reach data center patching where cost-efficiency and low latency are required
Key specifications
 Connector type: QSFP28 male to QSFP28 male
 Length: 2 m
 Data rate support: up to 100 Gbps (100GBase-CR4, InfiniBand capable)
 Cable type: passive direct attach twinax copper (30 AWG)
 Typical power consumption: passive design with negligible additional power draw
 Compliance: MSA-compliant QSFP28 electrical and mechanical specifications
How to use
Install the cable by firmly inserting each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked, ensuring the latch engages and the connector is fully seated. Use the 2 m length to route between adjacent rack units or neighbouring racks without excessive bending; observe manufacturer bend-radius recommendations. This passive DAC requires host hardware that supports passive QSFP28 twinax connections—verify compatibility with the target switches, servers or storage platforms before deployment. No external power or transceiver modules are required for operation.
Usage recommendations
To maintain reliable operation, avoid sharp bends and kinks, keep the cable clear of heat sources and secure it to prevent strain on connectors. Confirm that the network equipment firmware and port configuration support passive 100G DACs and test links after installation. For inventory planning, consider labeling both ends to simplify future maintenance and troubleshooting.
