Lenovo 00YL673 5M QSFP+ to 4xSFP+ Active Optic Cable

Overview

The Lenovo 00YL673 is a 5-meter active optic cable designed to connect a single QSFP+ port to four SFP+ ports using optical fiber for Ethernet networking. This cable supports multiple 10GbE links by breaking out one high-speed QSFP+ connection into four separate 10GbE SFP+ connections, making it ideal for data center environments where efficient and reliable high-bandwidth connections are essential. Its 16.4-foot length provides ample reach for typical within-rack or rack-to-rack setups, ensuring flexible deployment in server rooms and equipment racks.

Key features

• Breaks out one QSFP+ port into four independent 10GbE SFP+ links, enabling versatile network configurations
• Optical fiber transmission reduces signal loss and interference compared to copper cables, maintaining data integrity over longer distances
• Male QSFP+ connector on one end and four male SFP+ connectors on the other for straightforward connectivity with compatible devices
• 5-meter length balances reach and cable management, helping maintain tidy and organized network racks
• Compatible with servers, switches, and network adapters supporting QSFP+ and SFP+ interfaces, ensuring broad usability
• Active optic design enhances signal quality and supports high-speed data transfer in demanding network environments

Key specs

Connectivity and compatibility

This cable is designed to connect devices equipped with QSFP+ and SFP+ ports, such as top-of-rack switches, servers, and network adapters. It enables a single QSFP+ port to be split into four separate 10GbE SFP+ connections, which is useful for expanding network capacity without additional switch ports. The active optical design ensures compatibility with standard Ethernet protocols over fiber, making it suitable for high-performance data center networks and lab environments.

Ideal uses and environments

The Lenovo 00YL673 fits well in data centers and server rooms where high-bandwidth, low-latency connections are critical. It is a strong choice for linking top-of-rack switches to multiple servers, enabling efficient breakout of high-speed ports for better network utilization. This cable also works well in lab setups requiring reliable breakout connectivity with minimal signal degradation and neat cable management. Its optical fiber construction makes it suitable for environments where electromagnetic interference could affect copper cables.
