## Summary description

Direct attach QSFP28 copper cable by BlueOptics, 1 meter length, supporting 100GBASE-CR4 Ethernet links. The assembly uses 30AWG wiring and a QSFP28 interface for direct connections between switches, NICs and other 100GbE ports. Suitable for short-reach, high-bandwidth server-to-switch or switch-to-switch interconnects in data centers and networking racks.

## Long description

BlueOptics QSFP28 Direct Attach Cable 1 m is a factory-terminated copper assembly designed for short-reach 100 Gigabit Ethernet links. The cable uses a QSFP28 connector on each end and 30AWG conductors to deliver 100GBASE-CR4 performance for direct connections between switches, network interface cards (NICs) and other 100GbE ports in rack and data center environments. With a 1 metre length, this direct attach cable provides a simple, low-latency physical link where fiber transceivers are not required.
Advantages
The BlueOptics QSFP28 copper direct attach cable combines low electrical loss 30AWG wiring with a standard QSFP28 interface to provide reliable 100GBASE-CR4 connectivity. Its short, fixed-length design reduces component count and power consumption compared with active optical modules, and eliminates the need for separate transceivers. The integrated connectors are interoperable with equipment that supports QSFP28 passive copper assemblies, allowing straightforward, plug-and-play installation for high-bandwidth interconnects.
Suitable for
 Short-reach server-to-switch links within racks
 Switch-to-switch connections in top-of-rack and aggregation layers
 100GbE NIC to switch direct links
 High-density cabling in data centers and network closets
Key specifications
 Interface: QSFP28 to QSFP28
 Length: 1 m
 Standard: 100GBASE-CR4 (100 Gigabit Ethernet)
 Conductor gauge: 30 AWG
 Cable type: Passive direct attach copper
 Typical use: Short-reach, high-bandwidth interconnects
How to use
Insert each QSFP28 connector into the corresponding 100GbE QSFP28 port on the network devices until the latch engages. Confirm link status in the device management interface and verify that the port is negotiated to 100G and CR4 mode if applicable. Route the 1 m cable to avoid sharp bends or pinch points; maintain bend radii recommended by equipment vendors. For best signal integrity, avoid tight bundling with power cables and keep the cable within the same rack or adjacent racks where short-reach copper is appropriate.
Usage recommendations
Use this passive QSFP28 direct attach cable for short-distance, high-bandwidth connections where copper is permitted by your switch and NIC vendor. Check device compatibility lists for supported passive copper assemblies and confirm that transceiver ports accept QSFP28 DACs before deployment.
