## Summary description

The BlueOptics MCP7F00-A01AR-BL is a 2-meter DAC cable designed for high-speed data transfer. It features a QSFP28 connector on one end and four SFP28 connectors on the other, making it ideal for connecting multiple devices in data centers. This cable is built for reliability and performance in demanding environments.

## Long description

The BlueOptics MCP7F00-A01AR-BL is a 2 m Direct Attach Copper (DAC) twinax cable with a QSFP28 connector on one end and four SFP28 connectors on the other. Designed for short-reach high-speed interconnections, this passive 100G to 4×25G cable follows MSA-compatible form factors and is intended for rack-to-rack or intra-rack links in data centers and server rooms. The cable is black, weighs approximately 0.25 kg and is built for environments where reliable, low-latency electrical signal transmission is required.
Advantages
The DAC cable provides a compact single-assembly solution to split a 100G QSFP28 port into four 25G SFP28 links without additional active electronics, resulting in low power consumption and minimal latency. Passive construction reduces points of failure and simplifies deployment while maintaining MSA-compatible mechanical and electrical characteristics for broad platform compatibility. The short length and twinax copper design make it a cost-effective option for high-density racks and adjacent rack connections.
Suitable for
Connecting a QSFP28 100G port to up to four SFP28 25G ports within the same rack or neighboring racks
High-density switch-to-switch or switch-to-server links in data centers
Short-reach interconnects for storage systems and network appliances that support passive DAC twinax
Key specifications
Form factor: QSFP28 to 4×SFP28
Length: 2 meters
Transmission type: Passive twinax copper (Direct Attach Cable)
Nominal aggregate data rate: 100 Gbps (4×25 Gbps)
Colour: Black
Typical power consumption: near 0 W at cable (passive design)
Designed for short-reach electrical links within racks or between adjacent racks
How to use
Insert the QSFP28 connector into the 100G QSFP28 port on the source device and insert each SFP28 connector into the corresponding 25G SFP28 ports on the destination device(s). Ensure both devices support passive DAC twinax cables and that ports are powered off or follow hot-plug procedures recommended by the hardware manufacturers. Confirm link status on both ends after connection and verify that the network interfaces are configured for the intended 25G or 25G-lane aggregation mode.
Usage recommendations
Use this DAC cable for short-distance connections only and avoid routing it near high electromagnetic interference sources. Verify hardware compatibility with the target switch, server or NIC vendor, and perform a link test after installation. For best longevity, avoid sharp bends, excessive pulling force and exposure to extreme temperatures.
