## Summary description

BlueOptics QSFP28 Direct Attach Cable (DAC) provides a 100GBASE-CR4 Ethernet connection using a 26AWG twinax assembly with a 3 meter length. Designed for short-reach high-speed links between QSFP28 ports, it supports 100 Gigabit Ethernet interconnects in data center top-of-rack switches, routers and network appliances where a passive copper DAC is appropriate.

## Long description

The BlueOptics QSFP28 Direct Attach Cable is a passive 100GBASE-CR4 twinax assembly designed for short-reach, high-bandwidth connections between QSFP28 ports. At 3 meters length and constructed with 26AWG conductors, this blue direct attach cable delivers a reliable copper link for 100 Gigabit Ethernet interconnects in rack and chassis environments. It is intended for use where a passive DAC provides sufficient signal integrity without the need for optical transceivers.
Advantages
This direct attach cable offers low latency and high throughput for 100G links while providing a cost-effective alternative to optical modules for short distances. The QSFP28 form factor ensures compatibility with standard 100G QSFP28 ports, and the twinax construction with 26AWG wiring supports the electrical characteristics required for 100GBASE-CR4 operation. The fixed 3 m length simplifies rack planning and reduces the need for additional patching hardware.
Suitable for
Short-reach interconnects between 100G QSFP28 ports in top-of-rack switches
Direct connections between routers, switches and network appliances within the same cabinet or adjacent racks
High-density data center environments where passive copper DACs are preferred for cost and power efficiency
Key specifications
Interface: QSFP28 to QSFP28
Standard: 100GBASE-CR4
Cable type: Passive twinax copper
Conductor gauge: 26AWG
Length: 3 meters
Color: Blue
Typical use: Short-reach 100 Gigabit Ethernet links
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on network devices until the latch engages. Ensure both devices support passive Direct Attach Copper (DAC) connections and the same 100GBASE-CR4 electrical standard. Route the 3 m cable to avoid sharp bends and excessive strain on the connectors; maintain recommended bend radius for twinax cables and secure the cable to prevent movement within the rack.
Usage recommendations
Verify device compatibility and firmware settings for passive QSFP28 DACs prior to deployment. For best performance, avoid extended exposure to high temperatures and repeated mechanical stress on the cable assembly. Use the 3 m length for intra-cabinet or adjacent-rack connections; for longer spans, consider active copper or optical solutions.
