PRODUCT DETAILS

Features and applications

QDD-2X200G-2P5M — interface and application

Juniper QDD-2X200G-2P5M identifies the exact direct attach cable under review. Its electrical or optical interface, environmental limits and host software requirements should be reviewed together.

  • The QSFP-DD to QSFP56 interface is specified for 2 x 200 Gigabit Ethernet. Confirm the required operating mode on both ends of the link.
  • The listed reach is 2.5 m using Twinax copper. Use the specification table to check any separate fiber grades or operating standards.
  • The listed interface standard is QDD-400G-DAC; a matching mechanical connector alone does not establish interoperability.

Installation and compatibility checks

  • Check that both end connectors and the stated cable length match the rack layout.
  • Confirm the supported speed and lane mode on both host ports; breakout capability depends on the platform.
  • Allow routing clearance and follow the cable bend-radius requirements without loading the connector latches.
  • Review the breakout mode and remote endpoint requirements for the chosen host; this flag does not confirm every fan-out arrangement.
