100G and 200G Optical Transceivers Product Detail
200G QSFP56 DAC is a passive twinax direct-attach cable for in-rack and adjacent-rack direct interconnects, with length and compatibility defined by the ordered version.
Use the published model direction and key parameters for selection and sample planning. Confirm compatibility coding, optional temperature grade, and production parameters in the formal specification or order document.

200G QSFP56 DAC integrates both host ends and the cable assembly for fixed short-reach deployment. Confirm the exact length, both host models, port mode, FEC, routing space, temperature, compatibility coding and delivery version before ordering.
Selection FAQ
200G QSFP56 DAC is a passive Twinax assembly with no retimer, so FEC and lane mode are decided entirely by the two QSFP56 host ports. Confirm the FEC mode the target platform expects before ordering, because a passive cable cannot compensate for a host that assumes a retimed link.
Insertion loss across the Twinax pairs, the wire gauge of the ordered P/N and the equalization budget of each QSFP56 port it plugs into. 200G QSFP56 DAC is built to a fixed length and cannot be trimmed on site, so order it against the measured cable path rather than a nominal rack distance.
Give the host vendor, model and software version at both ends, the QSFP56 port or lane mode, the operating temperature range, the quantity per site and the target delivery date. For 200G QSFP56 DAC also state the exact length per link and the routing path it has to follow. Compatibility is confirmed per platform, so the host details matter as much as the optical specification.
