## Summary description

Passive Direct Attach Copper cable BlueOptics SFP56 to SFP56, compliant with 50GBASE-CR specification and 3 meters long. Designed for short-reach high-speed interconnects between switches, routers and network interface cards that accept SFP56 ports. Provides a low-latency, power-free connection for 50 Gbit/s links in data centers, server racks and network aggregation.

## Long description

BlueOptics passive SFP56 to SFP56 Direct Attach Cable 50GBASE-CR, 3 m is a twinax copper direct attach cable designed for short-reach 50 Gbit/s connections between SFP56 ports. It provides a low-latency, energy-efficient physical link suitable for interconnecting switches, routers and server network cards in racks and aggregation layers where SFP56 interfaces are available. The cable conforms to the 50GBASE-CR electrical specification and is supplied as a fixed-length 3 metre assembly with SFP56 form-factor plugs on both ends.
Advantages
The passive twinax construction eliminates the need for optical transceivers and active electronics in the cable, reducing power consumption and simplifying deployment. Using SFP56 connectors on both ends ensures direct compatibility with devices that accept SFP56 modules, while the 3 m length supports common in-rack and adjacent-rack connections. Latency is minimized compared with optical links that require separate transceivers, and the passive design typically offers a lower total cost of ownership for short-reach 50G links.
Suitable for
Short-reach 50 Gbit/s links inside server racks and between adjacent racks
Direct connections between SFP56 switch ports and network interface cards
Data center top-of-rack and leaf-spine aggregation where short copper links are acceptable
High-density patching panels and switch interconnects requiring low-latency links
Key specifications
Interface: SFP56 plug on both ends (SFP56 to SFP56)
Data rate: 50 Gbit/s (50GBASE-CR electrical specification)
Type: Passive twinax copper direct attach cable (DAC)
Length: 3 metres
Use environment: Short-reach, in-rack and adjacent-rack connections
How to use
Insert each SFP56 connector into the SFP56 port of the corresponding device until the module latches. Ensure that devices are powered down or that hot-swap procedures recommended by the device manufacturer are followed, if applicable. Verify link status on connected network devices and confirm the expected 50 Gbit/s link speed through management interfaces or diagnostic LEDs. Route the cable to avoid excessive bending; maintain minimum bend radius as advised by equipment manufacturers to preserve signal integrity.
Usage recommendations
Use this passive SFP56 direct attach cable for short, fixed-length 50G links where power efficiency and low latency are priorities. Avoid using passive twinax for runs beyond the supported short-reach distance; for longer links consider optical transceivers and fiber. Handle connectors by the housing, keep dust caps when not in use, and store the cable coiled without tight bends to maintain performance.
