## Summary description

The BlueOptics X2121A-1M-N-BL is a 1-meter InfiniBand fibre optic cable featuring QSFP connectors on both ends. Designed for high-speed data transmission, it ensures reliable connectivity in data centers and networking environments. The male/male configuration makes it versatile for various applications.

## Long description

The BlueOptics X2121A-1M-N-BL InfiniBand Fibre Optic Cable 1m QSFP Male/Male is a 1-meter high-density connection cable with QSFP connectors on both ends, designed for short-reach, high-speed interconnects in data centers and server racks. The cable supports InfiniBand and related 40 Gbps applications and is intended for linking switches, routers, storage systems and other networking equipment that accept QSFP-to-QSFP connections. Constructed to meet common MSA mechanical and electrical requirements, the cable offers a compact, low-latency link suitable for dense rack deployments.
Advantages
The cable provides a reliable 1 m QSFP-to-QSFP connection that minimizes signal loss and latency for short-distance links. Its standardized QSFP interface ensures interoperability with equipment that supports 40G InfiniBand and related protocols. The short length reduces cable clutter in racks and simplifies cable management while the passive design lowers power consumption compared with active optical modules. Manufactured using industry-grade components, the product is intended to deliver consistent performance in high-availability environments.
Suitable for
Interconnects between adjacent rack units and within rack switch-to-switch links
High-speed InfiniBand networking and 40 Gbps data transfers
Connections between servers, storage arrays and network appliances with QSFP ports
Key specifications
Length: 1 meter
Connector type: QSFP (male) to QSFP (male)
Supported protocols: InfiniBand and 40 Gbps Ethernet-class applications
Design: passive direct-attach twinax style for short-reach links
Cable gauge: approximately 30 AWG construction for short-distance high-speed signalling
How to use
Install the BlueOptics X2121A-1M-N-BL by inserting each QSFP male connector into the corresponding QSFP port of your networking devices until the connector latches. Ensure both devices support passive QSFP direct-attach connections and the same transmission protocol (for example InfiniBand or 40GBase-CR4). Route the cable to avoid sharp bends and mechanical strain; maintain the recommended bend radius specified by your hardware vendor. After physical installation, verify link status and data rate via device management interfaces and adjust configuration if required.
Usage recommendations
Use this 1 m QSFP cable for short, rack-level links where low latency and compact cabling are priorities. Verify compatibility with your switch or server firmware and confirm the device accepts passive QSFP twinax-style connections before deployment. Avoid electric and mechanical stress, and periodically inspect connectors for dust or damage to preserve signal integrity.
