Network Cable BlueLAN MCP7F00-A01AR30NM QSFP28 to 4xSFP28 100GBASE-CR4 2M Blue

The BlueLAN MCP7F00-A01AR30NM QSFP28 to 4xSFP28 100GBASE-CR4 2M Blue is a passive direct attach breakout cable engineered for 100 Gigabit Ethernet interconnects. It provides a QSFP28 connector on one end and four SFP28 connectors on the other, enabling a single 100G port to connect to four separate 25G lanes or devices. The cable uses AWG26 conductors and a 2 meter length to balance reach and signal integrity in short-reach high-density environments. The blue jacket improves visibility in rack installations and helps with cable management in data center and enterprise networking setups.

Advantages

This passive breakout cable delivers low latency and minimal insertion loss suitable for short-reach 100GBASE-CR4 links. The QSFP28-to-4xSFP28 configuration supports flexible port mapping and simplifies consolidation of high-speed uplinks into multiple downstream ports. AWG26 conductors provide consistent electrical performance across the 2 m length while the one-piece assembly reduces potential points of failure compared with separate transceiver solutions. The distinct blue color aids identification and organization in dense cabling environments.

Suitable for

• Data center top-of-rack (ToR) switch interconnects
• High-density aggregation and spine leaf architectures
• Short-reach server to switch connections
• Switch-to-switch 100G breakout implementations

Key specifications

• Connector type: QSFP28 to 4 × SFP28
• Standard supported: 100GBASE-CR4
• Cable length: 2 meters
• Conductor gauge: AWG26
• Cable type: Passive direct attach breakout
• Jacket color: Blue

How to use

Insert the QSFP28 end into the 100G-capable QSFP28 port on the switch or aggregation device, and insert each SFP28 connector into the corresponding SFP28 ports on the target devices. Ensure both ends are fully seated and the latches engage to maintain a reliable connection. Observe proper cable routing to avoid excessive bending radius and mechanical strain; secure the cable using rack cable management accessories if available. This cable requires no additional configuration and is recognized as a passive electrical link by compatible network equipment.

Usage recommendations

Use this cable for short-reach connections within racks or between adjacent racks. Avoid running the cable alongside high-power electrical lines to reduce potential interference and maintain the recommended minimum bend radius to preserve signal integrity. Verify port compatibility and breakout mapping on your network devices before deployment.
