QSFP-DD to 8x 50G SFP56-400G-AOC-2M7FT 400G QSFP-DD 8 x 50G PAM4 to 8 x 50G SFP56 25G NRZ Active Optical Breakout Cable, 2m (7ft)

The HT-manufactured QSFP-DD to 8x 50G SFP56-400G-AOC-2M7FT compatible cable provides 400G connectivity for multi-vendor equipment. This 2m (7ft) version is a factory-terminated active optical link with the optical engines and fiber integrated into the assembly, with an exact part number and length that can be matched directly to the equipment requirement.

• Fixed length and part number: 2m (7ft), QSFP-DD to 8x 50G SFP56-400G-AOC-2M7FT
• Cable construction: OM3
• Maximum power consumption: 10W (QSFP-DD End) 3W (SFP56 Per End)
• Minimum bend radius: 30mm

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 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.

QSFP-DD to 8x 50G SFP56-400G-AOC-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 8x 50G SFP56-400G-AOC-2M7FT occupies the middle of this family between QSFP-DD to 8x 50G SFP56-400G-AOC-1M3FT at 1m (3ft) and QSFP-DD to 8x 50G SFP56-400G-AOC-3M10FT at 3m (10ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 1m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The HT cable carries the compatibility configuration associated with QSFP-DD to 8x 50G SFP56-400G-AOC-2M7FT, while its mechanical assembly remains the fixed 2m (7ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Generic software can request a pre-order check.

This product is ordered as QSFP-DD to 8x 50G SFP56-400G-AOC-2M7FT in 2m (7ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

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.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
