Description

StarTech QSFP4SFP10C5 Cisco QSFP-4SFP10G-CU5M Compatible 5M Direct Attached Breakout Cable - 40Gbps PA

Overview

The StarTech QSFP4SFP10C5 is a 5-meter direct-attach breakout cable designed to connect a 40Gbps QSFP+ port on a network switch or server to four independent 10Gbps SFP+ ports. This cable is engineered for high-density data center environments where efficient port utilization and direct, short-reach connectivity are critical. It eliminates the need for separate transceivers and fiber optic cabling for short links, reducing cost and simplifying deployment. The QSFP4SFP10C5 is specifically designed for compatibility with Cisco QSFP-4SFP10G-CU5M configurations, ensuring seamless integration into existing Cisco-based networks.

Compatibility

This cable is engineered to be compatible with network devices featuring a 40Gbps QSFP+ port that require a breakout connection to four 10Gbps SFP+ devices. It is specifically validated for compatibility with Cisco QSFP-4SFP10G-CU5M configurations, making it suitable for integration into Cisco networking infrastructure. It functions as a passive cable, directly connecting the ports without requiring active power or signal conversion.

Installation Notes

The QSFP4SFP10C5 is a passive cable with a maximum power consumption of less than 0.1W, meaning it draws negligible power from the host ports. The operating temperature range is 0°C to 70°C, suitable for most standard data center environments. The cable jacket is constructed from PVC, offering flexibility and durability for in-rack installations. Ensure the connectors are fully seated in the QSFP+ and SFP+ ports for a stable connection.
