Juniper Networks QDD-2X100G Compatible 200G QSFP-DD 8 x 25G NRZ to 2 x 100G QSFP28 4 x 25G NRZ Passive Copper Breakout Cable

The QDD-2X100G compatible cable series is intended for Juniper Networks equipment requiring a 200G DAC connection. Its QSFP-DD to 2x QSFP28 configuration supports a passive copper twinax connection without separate optical modules or fiber patch cords, while the verified source lengths listed below make length selection explicit.

Passive DAC assemblies are normally used for short switch-to-switch, switch-to-server and rack-adjacent links. They draw very little power and avoid separate optical components, but the selected length must remain within the host and cable specification.

The QSFP-DD to 2x QSFP28 interface and 200G data rate must match the equipment at both ends. For breakout versions, confirm the lane mapping and the speed of every downstream port; matching connector shapes alone does not establish interoperability.

The assembly is configured for equipment that recognizes the QDD-2X100G series. Before shipment, we check connector identification, link establishment and electrical link stability, signal integrity and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the switch, server or accelerator model and software release for a pre-order compatibility review.

Quote HT part number QDD-2X100G, the required length from 0.5m (2ft), 1m (3ft), 2m (7ft) and 3m (10ft), and the OEM part number used by your equipment. The length-specific OEM identifiers above link to their own product pages so each reference can be ordered separately.

Every DAC assembly undergoes continuity and link testing, compatibility verification and a visual inspection of both connector ends. Cables are coiled without exceeding their minimum bend radius, fitted with connector protection and packed in anti-static bags or protective trays before cartoning. Project labels and packing lists are available for volume orders.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
