## Summary description

Passive direct-attach breakout cable by BlueOptics, model DAC-QSFP-4SFP-10G-1M. Provides a 1 m QSFP-to-4xSFP direct electrical connection supporting 100GBASE-CR4 on the QSFP end and four 25GBASE-CR lanes to SFP ends. Designed for short-reach aggregation or server-to-switch connections in data centers and network racks. Passive construction requires compatible ports and delivers low-latency, cost-effective interconnect.

## Long description

BlueOptics DAC-QSFP-4SFP-10G-1M is a passive direct-attach breakout cable engineered for short-reach high-density interconnects. The 1 m cable provides a QSFP interface on one end and four independent SFP interfaces on the other, enabling a single 100GBASE-CR4 port to split into four 25GBASE-CR electrical lanes. Its passive construction offers a low-latency, cost-effective connection for aggregation and server-to-switch links in data center and rack environments when used with compatible ports.
Advantages
This breakout cable delivers a compact and economical solution for consolidating high-throughput links without active electronics. By splitting a QSFP 100G connection into four 25G channels, it reduces cabling complexity and saves port density on switches and servers. The passive design eliminates the need for power at the cable, lowers latency compared with active optics, and minimizes maintenance points due to its simple, robust construction.
Suitable for
 Short-reach aggregation between top-of-rack switches and spine switches
 Direct server-to-switch connections in dense rack deployments
 High-density port consolidation where 100G to 4×25G breakout is required
 Lab and testing environments requiring reliable electrical breakout links
Key specifications
 Cable type: Passive direct-attach breakout cable
 Length: 1 meter
 Connector configuration: QSFP (one end) to 4 × SFP (other end)
 Supported signaling: 100GBASE-CR4 on QSFP side; 4 × 25GBASE-CR lanes to SFPs
 Latency: Low, typical of passive electrical interconnects
 Color: Blue (cable jacket)
 Suitable for short-reach, copper electrical connections within racks
How to use
Install the QSFP connector into the 100G-capable QSFP port on your switch or transceiver module and plug each SFP connector into the corresponding 25G SFP ports on target devices. Ensure that both ends support passive DAC connections and the switch/router firmware recognizes breakout operation for dividing a 100G port into four 25G lanes. Route the cable within the rack to avoid sharp bends and excessive mechanical stress, and secure it with cable management to maintain signal integrity.
Usage recommendations
Verify compatibility with your network equipment vendor’s supported direct-attach breakout configurations and ensure appropriate firmware or port settings are applied. Use this passive DAC for short-distance electrical connections inside racks or between adjacent racks; do not rely on it for longer distances or environments that require optical or active conversion.
