QSFP-DD to 8x 50G SFP56-400G-AOC-50M164FT 400G QSFP-DD 8 x 50G PAM4 to 8 x 50G SFP56 25G NRZ Active Optical Breakout Cable, 50m (164ft)

This 50m (164ft) AOC cable is built for multi-vendor equipment requiring the QSFP-DD to 8x 50G SFP56-400G-AOC-50M164FT interface. The 425Gbps (8x 53.125GGbps) link uses QSFP-DD to 8x 50G SFP56 and is supplied as one complete tested assembly.

The listed modulation format is PAM4. 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.

QSFP-DD to 8x 50G SFP56-400G-AOC-50M164FT occupies the middle of this family between QSFP-DD to 8x 50G SFP56-400G-AOC-30M98FT at 30m (98ft) and QSFP-DD to 8x 50G SFP56-400G-AOC-70M230FT at 70m (230ft). It adds 20m over the shorter option for extra routing clearance, while the next longer version adds another 20m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The rated power consumption is 10W (QSFP-DD End) 3W (SFP56 Per End). Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

This assembly uses OFNP jacket, minimum bend radius 30mm. 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, SFP56 MSA, IEEE 802.3cd. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP-DD to 8x 50G SFP56 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.

The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.

The extended 50m (164ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated AOC construction avoids a chain of separate modules and patch leads.

Each QSFP-DD to 8x 50G SFP56-400G-AOC-50M164FT compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe optical link operation, receive activity and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Generic platform should be included with the order.

Quote HT part number QSFP-DD to 8x 50G SFP56-400G-AOC-50M164FT with the required quantity. The 50m (164ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
