## Summary description

Passive SFP56 Direct Attach Cable by BlueOptics, supporting 50GBASE-CR data rates with a fixed 0.5 m length. Designed for short-reach high-speed interconnects between compatible SFP56 ports and network adapters, this DAC offers low-latency, direct copper connectivity and plug-and-play installation for switches, servers and NICs compatible with NVIDIA part 980-9I876-00G00A.

## Long description

BlueOptics SFP56 Direct Attach Cable 50GBASE-CR passive 0.5 m is a short-reach copper interconnect designed for direct connection between compatible SFP56 ports and network adapters. The cable supports 50GBASE-CR data rates and offers a fixed length of 0.5 m for rack- and chassis-level connections. It provides low-latency, high-bandwidth connectivity suitable for switches, servers and network interface cards that accept SFP56 passive direct attach cables.
Advantages
This passive direct attach cable delivers a cost-effective physical link for 50 Gbit/s connections with minimal power consumption compared to active optical transceivers. The fixed 0.5 m length reduces signal attenuation and is ideal for short distance links inside racks or between adjacent devices. Plug-and-play compatibility simplifies installation and reduces configuration time when used with SFP56-compliant ports and compatible network adapters.
Suitable for
Short-reach connections inside server racks and network cabinets
Direct links between switches and top-of-rack servers
High-density environments requiring low-latency 50 Gbit/s links
Upgrading existing copper interconnects to 50GBASE-CR speeds
Key specifications
Interface: SFP56 direct attach cable (DAC), passive
Data rate: 50 Gbit/s (50GBASE-CR)
Length: 0.5 m fixed
Physical medium: Twinax copper assembly
Typical use: Short-reach, rack-level interconnects
Latency: Low, suitable for latency-sensitive applications
How to use
Install the cable by inserting each SFP56 connector into the corresponding port on the devices to be linked until the latch engages. Ensure both devices support passive SFP56 direct attach cables and are powered off or traffic is halted during hot-plug operations if required by the equipment vendor. After insertion, verify link status through device LEDs or management interfaces and confirm 50 Gbit/s link negotiation. No additional configuration is required for basic connectivity; driver or firmware compatibility on the network adapter should be confirmed if the device enforces vendor compatibility lists.
Usage recommendations
For reliable operation, use the cable for short, direct connections within the same rack or between adjacent racks only. Avoid sharp bends and excessive pulling force on the cable assembly. Verify compatibility with your switch or adapter firmware and consult equipment documentation for hot-plug guidelines and supported passive DAC modules.
