Key Features

  • SFP56 to QSFP56 interface
  • 2 m cable length
  • Direct attach copper design
  • Short-reach Ethernet connectivity
  • 200 Gigabit Ethernet class
  • Juniper Networks cable assembly
  • Passive copper interconnect
  • Connect 200G-class ports using SFP56 to QSFP56 direct attach copper
Built for short-reach 200G connectivity, this Juniper DAC links SFP56 and QSFP56 interfaces with a direct copper path that keeps deployments simple and predictable. It is a practical fit for top-of-rack and adjacent-rack connections where optical reach is unnecessary and cable management still needs to stay disciplined. The 2 m length gives teams a little more routing flexibility than a 1 m assembly while preserving the low-latency characteristics and lower power profile associated with direct attach copper. That makes it useful in production environments where port density is high, rack space is tight, and every added optic increases cost and operational complexity. For infrastructure teams standardizing on 200G Ethernet, this cable supports efficient short-run interconnects without adding separate transceivers. The result is a cleaner bill of materials, fewer components to stock, and a more controlled physical layer for high-speed switching environments.

Ideal For

  • Link a QSFP56 switch port to an SFP56-capable device in the same rack
  • Connect adjacent rack equipment in a 200G Ethernet fabric
  • Reduce optical module usage in short-reach deployments
  • Support clean cable routing in dense top-of-rack environments

Why This Product

  • 12 m length offers more routing flexibility than shorter DACs
  • 2Direct attach copper avoids separate optical modules
  • 3Built for short-reach 200G Ethernet links
  • 4Fits dense rack environments with lower cabling overhead
