## Summary description

Direct attach QSFP28 copper cable by BlueOptics, 2.0 meters length, supporting 100GBASE-CR4 Ethernet links. Constructed with 30AWG conductors, designed for short-reach high-speed connections between QSFP28 ports in switches, routers and network appliances. Suitable for data center top-of-rack links, server interconnects and switch stacking.

## Long description

The BlueOptics QSFP28 Direct Attach Cable 2.0 m is a passive copper interconnect designed for short-reach 100GBASE-CR4 links. With a QSFP28 connector on each end and 30AWG conductors, this 2.0‑meter cable provides a straightforward physical layer connection between QSFP28 ports in switches, routers and network appliances. It is intended for use in environments where low latency and high throughput are required over short distances, such as data center top-of-rack cabling, server interconnects and switch stacking.
Advantages
This direct attach cable offers a cost-effective and low-power alternative to optical modules for 100G connections over short distances. The 30AWG construction balances flexibility and signal integrity while the QSFP28 form factor ensures compatibility with standard 100GBASE-CR4 ports. As a copper cable assembly, it requires no separate transceivers, simplifying deployment and reducing component count in rack environments.
Suitable for
Top-of-rack connections in data centers
Server-to-switch uplinks and server interconnects
Switch stacking and adjacent chassis links
Short-reach 100GBASE-CR4 Ethernet links
Key specifications
Form factor: QSFP28 to QSFP28 direct attach copper cable
Length: 2.0 meters
Data rate: 100 Gbps aggregate (100GBASE-CR4)
Conductor gauge: 30 AWG
Connector type: QSFP28 duplex copper assembly
Application: Short-reach interconnects for QSFP28 ports
How to use
Insert each QSFP28 connector into the corresponding 100G-capable QSFP28 ports on your switches, routers or servers until the latch engages. Verify link status and negotiate settings using the device management interface or network monitoring tools. For reliable operation, ensure port firmware and device configurations support 100GBASE-CR4 copper connections and that ports are rated for passive DAC use.
Usage recommendations
Route the cable to avoid sharp bends and mechanical stress; maintain a bend radius appropriate for 30AWG assemblies. Use labeled cable management and consistent port mapping to simplify maintenance. For distances beyond the specified 2.0 meters or when isolation and longer reach are required, consider optical transceivers and fiber cabling instead of a passive DAC.
