Panduit PHQ4SFP2A2MBL QSFP28 to SFP28 Breakout Cable

Product Description

The PANDUIT PHQ4SFP2A2MBL is a QSFP28 to SFP28 breakout copper cable designed for high-density data center and network infrastructure applications. This passive direct-attach copper (DAC) assembly splits a single 100G QSFP28 port into four independent 25G SFP28 connections, enabling flexible port utilization without active optical components. Network technicians and data center infrastructure professionals install this cable to consolidate uplinks and reduce switch port costs. The copper construction keeps latency low and eliminates the need for separate transceivers at each end.

This breakout cable is suited for top-of-rack switching environments, spine-leaf architectures, and server-to-switch interconnects where 100G to 4x25G fanout is required. It is a direct-attach solution, meaning no additional transceivers or media converters are needed. Installation is plug-and-play within compatible QSFP28 and SFP28 port ecosystems commonly found in enterprise and hyperscale data center deployments.

Key Features

• QSFP28 to 4x SFP28 breakout configuration for 100G to 4x25G fanout
• Passive direct-attach copper construction for low latency and low power consumption
• No separate transceivers required at either end
• Plug-and-play installation in compatible QSFP28 and SFP28 switch ports
• Sold as a single unit

Compatibility

Designed for use with network switches and servers equipped with QSFP28 host ports and SFP28 target ports in 100G and 25G Ethernet infrastructure environments.

Installation Notes

This cable is installed by qualified network technicians or data center infrastructure personnel. Power down or administratively disable the affected switch ports before seating or removing QSFP28 and SFP28 connectors to prevent interface errors. Ensure the QSFP28 connector is fully seated and the bail latch is secured before bringing the port online. Follow site change-management procedures and consult the switch manufacturer documentation for port configuration requirements.
