CBO Cable CBL-430-BO 30 m QSFP Male to Male 40 Gbit/s

Direct-attach CBO Cable CBL-430-BO is a 30 m QSFP male-to-male assembly engineered for 40 Gbit/s connections between QSFP ports. Intended for short-range high-speed links in data centres, server rooms and test labs, the cable provides a single-cable solution for 40 Gigabit Ethernet and other 40 Gbit/s serial interfaces. Its fixed QSFP male connectors and controlled impedance construction enable consistent throughput and low latency for aggregation, top-of-rack and switch-to-switch interconnects.

Advantages

The CBO Cable CBL-430-BO combines a long 30 m reach with QSFP male-to-male connectivity to support 40 Gbit/s links without the need for separate transceivers. Its direct-attach design reduces component count and simplifies rack cabling. The assembly is designed for stable electrical performance across the operating frequency needed for 40 GbE, resulting in reliable data transmission and reduced signal loss over short distances.

Suitable for

• 40 Gigabit Ethernet links between switches and routers
• Connections between servers and top-of-rack switches
• High-speed interconnects in data centres and colocation facilities
• Lab and testing environments requiring low-latency 40 Gbit/s links

Key specifications

• Connector type: QSFP male to QSFP male
• Rated data rate: 40 Gbit/s
• Cable length: 30 m
• Application: short-range direct-attach high-speed interconnects
• Cable topology: fixed assembly for direct QSFP port connection

How to use

Ensure both devices support QSFP direct-attach connections and 40 Gbit/s operation. Route the cable to avoid sharp bends and excessive tensile stress; observe manufacturer-recommended minimum bend radius. Align each QSFP male connector with the corresponding QSFP port and insert until the connector latches securely. Verify link status on connected devices and confirm negotiated speed and link integrity before deploying into production.

Usage recommendations

For optimal performance, install the cable in environments within the operating temperature and humidity ranges of your networking equipment, avoid tight bundling with power cables, and inspect connectors for contamination before insertion. Use this direct-attach assembly for short-range 40 Gbit/s links where QSFP-to-QSFP direct connectivity is supported.
