QSFP-DD to 8x 50G SFP56-400G-AOC-5M16FT 400G QSFP-DD 8 x 50G PAM4 to 8 x 50G SFP56 25G NRZ Active Optical Breakout Cable, 5m (16ft)

This HT cable matches the QSFP-DD to 8x 50G SFP56-400G-AOC-5M16FT requirement for multi-vendor equipment. The 5m (16ft) assembly supports 400G operation and provides a factory-terminated active optical link with the optical engines and fiber integrated into the assembly; its complete electrical and mechanical details are listed below.

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.

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 5m (16ft) length gives QSFP-DD to 8x 50G SFP56-400G-AOC-5M16FT more freedom for adjacent-rack and row-end deployments. The integrated optical assembly should be supported along its route without tight bends or connector pull loads; the AOC specification and host support must still match the intended link.

QSFP-DD to 8x 50G SFP56-400G-AOC-5M16FT occupies the middle of this family between QSFP-DD to 8x 50G SFP56-400G-AOC-3M10FT at 3m (10ft) and QSFP-DD to 8x 50G SFP56-400G-AOC-7M23FT at 7m (23ft). It adds 2m over the shorter option for extra routing clearance, while the next longer version adds another 2m. 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.

Each QSFP-DD to 8x 50G SFP56-400G-AOC-5M16FT 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.

When ordering, specify QSFP-DD to 8x 50G SFP56-400G-AOC-5M16FT, cable length 5m (16ft) 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.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, QSFP-DD to 8x 50G SFP56-400G-AOC-5M16FT and the 5m (16ft) length for easier inventory control.

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.
