Cabo de cobre InfiniBand Direct Attach CBO EX-QSFP-40GE-DAC-0.5M-BL 0,5 m

CBO InfiniBand Direct Attach Copper Cable EX-QSFP-40GE-DAC-0.5M-BL 0.5 m is a short-length copper link with QSFP connectors designed for 40 Gigabit connections. The cable provides a direct electrical connection between QSFP ports without the need for optical transceivers, enabling low-latency, high-throughput links for rack-level or adjacent-rack interconnects in data centre environments. With a half-metre length, this DAC cable is intended for short-range server-to-switch or switch-to-switch connections where predictable performance and minimal insertion loss are required.

Advantages

The CBO InfiniBand DAC delivers deterministic latency and consistent signal integrity suitable for high-performance computing and storage networks. Its QSFP terminations simplify installation by plugging directly into compatible QSFP ports, reducing component count and power consumption compared with optical modules. The short 0.5 m copper construction reduces cost for short-reach links while offering reliable physical layer connectivity and minimal heat generation in dense rack deployments.

How to use

Install the 0.5 m QSFP DAC by inserting each QSFP connector into the corresponding QSFP ports on the devices to be connected, ensuring secure seating and latch engagement. Verify that both endpoints support QSFP direct-attach copper connections and configure the devices for the desired 40 Gigabit link speed if necessary. Monitor link status and performance through the connected devices' management interfaces and ensure cable routing avoids sharp bends and mechanical stress to maintain signal integrity.
