## Summary description

The BlueLAN Q4S28P301.5-01P is a passive Direct Attach Copper (DAC) cable designed for high-speed data transmission. It features a QSFP28 connector on one end and four SFP28 connectors on the other, supporting 100 Gigabit to 4x25 Gigabit connections. With a length of 1.5 meters, this cable is ideal for connecting hardware in racks and across adjacent racks, ensuring reliable performance and reduced latency in data centers.

## Long description

The BlueLAN Q4S28P301.5-01P is a passive Direct Attach Copper (DAC) cable that provides a 100G QSFP28 to 4×25G SFP28 breakout connection at a fixed 1.5 meter length. Designed for short-reach, high-bandwidth interconnections in server rooms and data centers, this cable delivers a straightforward physical link between a QSFP28 port and up to four SFP28 ports without requiring transceivers. Its passive copper construction offers low latency and stable signal integrity for aggregated 100 Gigabit to 4×25 Gigabit deployments.
Advantages
The cable delivers cost-effective, low-power connectivity with minimal signal conversion overhead, suitable for top-of-rack and adjacent-rack connections. Passive DAC construction eliminates the need for additional optical transceivers, reducing component count and simplifying inventory. The 1.5 m length balances reach and cable management for dense rack environments while maintaining reliable electrical performance and low latency for latency-sensitive applications.
Suitable for
Connecting a QSFP28 switch or NIC to four SFP28 ports on servers or line cards
Top-of-rack (ToR) and adjacent-rack interconnects in data centers
High-density switch fabrics and aggregation panels requiring 100G breakout to 25G
Environments where low latency and reduced power consumption are priorities
Key specifications
Connector type: QSFP28 to 4 × SFP28 breakout
Data rate: 100 Gigabit aggregated, 4 × 25 Gigabit channels
Medium: Passive Direct Attach Copper (DAC)
Length: 1.5 m
Typical use case: Short-reach rack/backplane interconnects
How to use
Install the QSFP28 end into the 100G QSFP28 port on the switch or network card and plug each SFP28 connector into the target SFP28 ports on servers, line cards, or breakout panels. Ensure both endpoints support passive DAC cabling and compatible module breakout configurations. Route the cable to avoid sharp bends and mechanical stress; secure using rack cable management accessories as needed. No external power or transceivers are required for operation.
Usage recommendations
Verify port compatibility in device specifications before deployment. Use the 1.5 m length for short-reach connections within the same rack or adjacent racks to maintain signal integrity. Avoid repeated flexing and excessive pulling force during installation and label both ends for easier troubleshooting and inventory tracking.
