QSFP-DD Cages & Connectors for 400G Optical Transceivers

QSFP-DD cages and QSFP-DD connectors are purpose-built for 400 Gigabit optical modules, combining high-density design with advanced EMI shielding and thermal management. A QSFP-DD cage secures the double-density module and provides grounding/EMI paths; a QSFP-DD connector maintains signal fidelity across multiple high-speed lanes.

In hyperscale data centers and aggregation switches, 400G QSFP-DD cages support intensive thermal loads and routing, while matched 400G QSFP-DD connectors ensure low-loss channel performance and durable mating cycles.

Trxcom supplies QSFP-DD cages with integrated thermal features and EMI springs, plus precision QSFP-DD connectors with controlled impedance and robust plating options. All components are engineered for MSA alignment and validated under rigorous mechanical and electrical tests.

For next-generation 400G deployments, our QSFP-DD cages and QSFP-DD connectors provide the mechanical, thermal, and EMI controls needed for sustained high-bandwidth operation.

Frequently Asked Questions about QSFP-DD Cages & Connectors

Q: What is QSFP-DD used for?
A: QSFP-DD supports 400G (and beyond) optical modules in data center switch fabrics requiring very high port density and bandwidth.

Q: Do QSFP-DD cages require special thermal design?
A: Yes, QSFP-DD cages often incorporate thermal features and airflow considerations due to higher power densities.

Q: Are QSFP-DD connectors compatible with legacy QSFP sockets?
A: QSFP-DD is a distinct form factor; compatibility depends on host connector design—consult Trxcom for migration options.
