Key Features

400GBASE-CU passive direct-attach copper signaling
1 m fixed cable length for adjacent equipment
QSFP-DD connectors at both cable ends
Cisco and Juniper Networks compatibility
TAA-compliant construction
Connect 400G QSFP-DD ports through a fixed 1 m passive 400GBASE-CU copper link.

Link adjacent 400G equipment with a fixed 1 m copper assembly rather than separate optical modules and patch fiber. AddOn QSFPDD-400G-PDAC1M-CJ-AO is a passive 400GBASE-CU QSFP-DD direct-attach cable for short interconnects between high-density network ports. Its attached QSFP-DD connectors create a complete end-to-end cable assembly for the specified reach. The 1 m length fits equipment positioned in the same rack or immediately adjacent rack locations, including switch-to-switch, switch-to-router, and switch-to-server interconnects where the port spacing is known. Passive copper operation avoids the additional active electronics used by longer-reach cable types. It is suited to short 400G links that require the compact cable routing and direct port connection of a DAC. This specific assembly combines 400GBASE-CU signaling, QSFP-DD interfaces, passive construction, and a 1 m fixed length. It is identified for Cisco and Juniper Networks compatibility and carries TAA compliance, making those attributes central to selecting it over other cable lengths or interface formats. Verify that both intended ports use the required QSFP-DD 400G interface and that 1 m provides sufficient routing allowance before installation.

Ideal For

Same-rack 400G switch-to-switch uplinks between adjacent network devices.
Short QSFP-DD connections from a 400G switch to a router or server NIC.
High-density rack interconnects where a 1 m fixed-length copper path fits the cable route.

Why This Product

1Uses passive copper construction for short-reach 400G connections.
2Provides a fixed 1 m reach for closely positioned equipment.
3Uses QSFP-DD interfaces for 400GBASE-CU port connections.
4Combines Cisco and Juniper Networks compatibility with TAA compliance.

Frequently Asked Questions

How do I confirm QSFPDD-400G-PDAC1M-CJ-AO is the right part for my deployment?▾

Confirm that both endpoints have 400G QSFP-DD ports, that a passive 400GBASE-CU connection is supported by the intended equipment, and that 1 m covers the installed cable path. This cable is intended for Cisco and Juniper Networks environments.

What type of cable is QSFPDD-400G-PDAC1M-CJ-AO?▾

It is a passive 400GBASE-CU direct-attach copper cable with QSFP-DD connectors. The cable provides a fixed 1 m connection between compatible 400G QSFP-DD ports and does not use separate optical transceivers or fiber patch cables.

Where is a 1 m 400G QSFP-DD DAC typically used?▾

A 1 m direct-attach cable is commonly used for same-rack links between adjacent switches, routers, or servers. The fixed short length is appropriate when equipment placement is known and a compact copper interconnect is required.

Does this 400G direct-attach cable meet TAA requirements?▾

Yes. This cable is specified as TAA compliant. That designation is relevant where purchasing requirements call for products meeting Trade Agreements Act sourcing criteria, alongside the required 400G QSFP-DD interface and cable reach.
