Cisco QDD-400-AOC15M Compatible 400G QSFP-DD 8 x 50G PAM4 Active Optical Cable, 15m (49ft)

Designed for hosts that recognize QDD-400-AOC15M, this QSFP-DD to QSFP-DD cable delivers 400G transmission over a fixed 15m (49ft) assembly. Its AOC construction provides a factory-terminated active optical link with the optical engines and fiber integrated into the 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.

QDD-400-AOC15M occupies the middle of this family between QDD-400-AOC10M at 10m (33ft) and QDD-400-AOC20M at 20m (66ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 5m. 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 8W 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 8x 50G-PAM4. Listed interface and protocol references include IEEE 802.3cd, OIF-CEI-04.0, QSFP-DD MSA,QSFP-DD-CMIS-rev4p0. Confirm that the host firmware and port configuration support the same operating 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 extended 15m (49ft) 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.

The HT cable carries the compatibility configuration associated with QDD-400-AOC15M, while its mechanical assembly remains the fixed 15m (49ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Cisco software can request a pre-order check.

When ordering, specify QDD-400-AOC15M, cable length 15m (49ft) 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.

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.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
