This 2m (7ft) DAC cable is built for multi-vendor equipment requiring the QSFP-DD to 4x QSFP28-200G-DAC-2M7FT interface. The 200G link uses QSFP-DD to 4x QSFP28 and is supplied as one complete tested assembly.

The listed modulation format is NRZ. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.
The QSFP-DD to 4x QSFP28 configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.
A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.
QSFP-DD to 4x QSFP28-200G-DAC-2M7FT provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.
QSFP-DD to 4x QSFP28-200G-DAC-2M7FT occupies the middle of this family between QSFP-DD to 4x QSFP28-200G-DAC-1.5M5FT at 1.5m (5ft) and QSFP-DD to 4x QSFP28-200G-DAC-2.5M8FT at 2.5m (8ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.
This assembly uses 28 AWG conductors, PVC jacket, minimum bend radius 10mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include QSFP-DD MSA Rev. 5.0, CMIS Rev 4.0, IEEE 802.3cd. Confirm that the host firmware and port configuration support the same operating mode.
Each QSFP-DD to 4x QSFP28-200G-DAC-2M7FT compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Generic platform should be included with the order.
When ordering, specify QSFP-DD to 4x QSFP28-200G-DAC-2M7FT, cable length 2m (7ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.
No. It is manufactured by HT under our own manufacturer identity.
No. This page is dedicated to 2m (7ft) and part number QSFP-DD to 4x QSFP28-200G-DAC-2M7FT. Other lengths have their own part numbers and product pages.
No. The connectors and cable form one complete direct-attach assembly. Do not attempt to detach or replace either end.
No. Follow the specified minimum bend radius and route the 2m (7ft) assembly without tight folds, sharp edges or excessive cable ties.
Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.
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.
