## Summary description

BlueOptics passive Direct Attach Cable (DAC) SFP28 to SFP28, compatible with NVIDIA 980-9I63N-00A002. Supports 25GBASE-CR single‑lane 25 Gbit/s connectivity over a 2 meter AWG30 copper twinax link. Designed for short‑reach connections between SFP28 ports in switches, servers and network appliances where low latency and power efficiency are required.

## Long description

BlueOptics Direct Attach Cable SFP28 to SFP28 is a passive twinax copper cable designed for 25GBASE-CR single‑lane Ethernet links. With a 2 meter length and AWG30 conductor, the cable provides a direct electrical connection between SFP28 ports in switches, servers and network appliances. The passive design requires no external power or transceiver electronics, offering a low‑latency, power‑efficient option for short‑reach interconnects where reliable 25 Gbit/s performance is needed.
Advantages
The cable delivers native 25 Gbit/s throughput over a short copper twinax link, minimizing latency and power consumption compared with active optics or separate transceiver modules. Its SFP28-to-SFP28 form factor ensures plug-and-play compatibility with SFP28 ports, simplifying installation and reducing component count in rack environments. The AWG30 construction balances flexibility and signal integrity for stable connections at the specified 2 m reach.
Suitable for
Interconnecting SFP28 ports on switches and top-of-rack devices
Direct server-to-switch connections in data center racks
High-performance network appliances requiring single‑lane 25G links
Low-latency short-reach links in hyperconverged and virtualization environments
Key specifications
Interface: SFP28 to SFP28
Standard: 25GBASE-CR (single‑lane 25 Gbit/s)
Length: 2 m
Cable type: Passive twinax copper (direct attach cable)
Conductor gauge: AWG30
Form factor: Fixed direct-attach with integrated SFP28 connectors
How to use
Insert each SFP28 connector into the corresponding SFP28 port until it clicks into place, ensuring the port latch is engaged. Use the cable for short-reach connections up to 2 m between compatible SFP28 ports on switches, servers or network appliances. No external power or configuration is required for the passive cable itself; configure link speed and network settings on connected devices according to your network design. For removal, depress the connector latch and pull the cable straight out to avoid straining the port.
Usage recommendations
Verify device compatibility with passive SFP28 DACs before deployment and ensure port settings are configured for 25G operation. Route the cable to avoid sharp bends and mechanical strain; maintain bend radius recommended by the equipment manufacturer. For reliable performance in rack installations, label both ends and keep cable length within the specified 2 m range.
