Network fiber optic patch cable CBO BlueOptics X66120-5-BL QSFP 5 m 40 Gbit/s

CBO BlueOptics X66120-5-BL QSFP 5 m is a fiber optic patch cable engineered for short‑range, high‑speed interconnects. With QSFP connectivity and support for 40 Gbit/s transmission, this 5‑metre cable is intended for use in data centers, server racks and network equipment cabinets where compact, reliable links are required. The cable provides consistent signal integrity for links between switches, servers and transceivers over short distances.

Advantages

The cable offers 40 Gbit/s-capable QSFP connectivity in a compact 5 m length, reducing excess slack in dense rack installations. Its fiber optic design ensures low signal loss and immunity to electromagnetic interference, supporting reliable high-throughput data transfer. The construction is optimized for short-range applications, enabling stable links between network devices while maintaining a small physical footprint.

Suitable for

• Short-range links in data centers and server rooms
• Interconnects between switches, servers and QSFP transceivers
• High-density rack installations requiring compact cabling
• Applications needing 40 Gbit/s throughput over optical fiber

Key specifications

• Connector type: QSFP optical interface compatible with 40 Gbit/s modules
• Length: 5 metres
• Supported data rate: up to 40 Gbit/s
• Transmission medium: fiber optic
• Intended range: short‑reach links within racks and between adjacent equipment

How to use

Plug each QSFP connector into the corresponding QSFP port on network devices or transceiver modules, ensuring connectors are clean before insertion to maintain signal quality. Route the 5 m cable within the rack or cabinet to avoid sharp bends and excessive stress on the connectors. Verify link status on both endpoints after connection and follow device-specific procedures for link negotiation or port configuration if necessary.

Recommendations

Keep connector end faces protected when not in use, handle the fiber cable without kinking, and maintain bend radii recommended by industry standards. Use in environments consistent with short‑reach optical cabling and pair with compatible QSFP ports and transceivers to achieve reliable 40 Gbit/s performance.
