## Long description

BlueOptics passive 50GBASE-CR SFP56 to SFP56 Direct Attach Cable, 2 m is a copper direct attach cable designed for short-reach 50 Gigabit Ethernet connections between compatible SFP56 ports. The cable provides a plug-and-play physical link for switches, routers and servers that support SFP56 connectors and 50GBASE-CR signaling. With a 2 meter length and SFP56 termination on both ends, it is intended for rack-to-rack, top-of-rack and within-rack connections where passive copper DACs are supported.
Advantages
This passive BlueOptics DAC offers low latency and low power consumption compared with active or optical alternatives, as no transceiver electronics or separate fiber pairs are required. Installation is straightforward thanks to SFP56 form-factor compatibility on both ends, and the fixed copper medium provides predictable signal integrity for short distances. The cable’s 2 m length balances reach and cable management in dense data center and server-room environments.
Suitable for
Short-reach 50 Gigabit Ethernet links between switches or routers
Rack-to-rack and within-rack connections in data centers
Direct server-to-switch connections with SFP56 ports
Environments prioritizing low latency and low power interconnects
Key specifications

How to use
Insert each SFP56 connector into the corresponding SFP56 port on network equipment until the latch engages. Ensure both devices are powered and that their firmware and port settings support 50GBASE-CR passive DAC operation. Verify link status using the device management interface or port LEDs. No additional transceivers or fiber patching are required. For replacement, power down the connected devices if recommended by the equipment vendor before removing the cable.
Usage recommendations
Place the cable to avoid sharp bends and excessive strain at the connector ends. For best performance, use this passive DAC only within the supported 2 m distance and with devices that explicitly support SFP56 passive copper modules. If hot-swapping is required, follow the equipment manufacturer's guidance to prevent link flapping or hardware issues.
