## Summary description

Direct attach copper cable BlueOptics QSFP28 designed for 100GBASE-CR4 links, NVIDIA compatible. Length 2 m, conductor gauge 30 AWG. Used for short-reach high-speed connections between QSFP28 ports in switches, routers and servers. Provides low-latency, cost-effective connectivity for data center uplinks, server-to-switch or switch-to-switch interconnects.

## Long description

BlueOptics QSFP28 Direct Attach Cable 100GBASE-CR4 is a copper twinax cable engineered for short-reach 100 Gigabit Ethernet connections. Designed for QSFP28 ports, this 2 m, 30 AWG cable provides a direct-attach solution compatible with NVIDIA equipment and other devices that support 100GBASE-CR4. The cable is intended for high-speed links between switches, routers and servers where low latency and cost efficiency are priorities.
Advantages
This direct attach cable offers a reliable, low-latency connection with reduced power consumption compared with active optical alternatives for very short distances. Its QSFP28 connector form factor supports 100GBASE-CR4 signaling and simplifies rack cabling by eliminating separate transceivers. With a 2 m length and 30 AWG conductors, the cable balances flexibility and signal integrity for data center topologies and high-density interconnects.
Suitable for
Short-reach 100G links between QSFP28 ports in switches and routers
Server-to-switch uplinks in data center racks
Switch-to-switch interconnects within the same equipment row or aisle
Environments requiring NVIDIA-compatible 100G direct-attach solutions
Key specifications
Standard: 100GBASE-CR4 over QSFP28 copper twinax
Connector type: QSFP28 male to QSFP28 male
Length: 2 meters
Conductor gauge: 30 AWG
Media: Direct-attach copper (twinax)
Compatibility: Designed for QSFP28 ports and compatible with NVIDIA devices supporting 100GBASE-CR4
How to use
Insert the QSFP28 connectors into the corresponding QSFP28 ports on networking equipment until they latch. Ensure both devices support 100GBASE-CR4 signaling and are powered down or set to allow hot-plugging per the device manufacturer’s guidance if required. After connection, verify link status through the equipment management interface and monitor error counters to confirm signal integrity. For cable routing, avoid sharp bends and maintain appropriate separation from sources of electromagnetic interference.
Usage recommendations
Use this direct attach cable for short-distance, high-speed interconnects inside racks or between adjacent racks where a low-latency, cost-effective 100G link is required. Do not extend beyond recommended distances for passive twinax copper to avoid degraded performance. Handle connectors carefully to avoid contamination and inspect ports and cable ends before insertion.
