The QSFP-DD to QSFP-DD-400G-AOC-15M49FT compatible assembly is a 400G AOC cable for Generic hosts, built in 15m (49ft) with QSFP-DD to QSFP-DD. It serves as one complete direct-attached link, while the compatibility and diagnostic checks below address the host-specific identification needed in a mixed-equipment environment.

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.
This 15m (49ft) assembly is intended for routes that shorter members of the same family cannot serve comfortably. Before ordering, document the actual pathway and the space available for service access. During installation, secure the integrated optical cable and both optical engines without compressing it into an undersized bundle or leaving its weight suspended from the ports. Within this family, QSFP-DD to QSFP-DD-400G-AOC-10M33FT is shorter at 10m (33ft), while QSFP-DD to QSFP-DD-400G-AOC-20M66FT is the next longer choice at 20m (66ft); comparing those two boundaries helps avoid both tension and unnecessary slack.
QSFP-DD to QSFP-DD-400G-AOC-15M49FT occupies the middle of this family between QSFP-DD to QSFP-DD-400G-AOC-10M33FT at 10m (33ft) and QSFP-DD to QSFP-DD-400G-AOC-20M66FT 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.
A mixed-vendor link should be documented at both ends, not treated as one generic connection. Confirm which OEM identity each host expects and whether the two ends use the same compatibility requirement. The related brand links below help locate equivalent-length assemblies, while the physical form factor and lane arrangement must still agree across the complete path. For this assembly, the minimum bend radius is 30mm; the stated power consumption is 8W Per End; the jacket material is OFNP.
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.
Testing addresses the brand-specific identification as well as the operating link and available diagnostics. The same physical cable family can require a different host identity for another equipment vendor, so the intended platform should be supplied when a deployment combines multiple brands or unusual hardware revisions. Where supported by the host, receive activity and diagnostic indications are reviewed together with the established link.
For mixed-vendor projects, identify the equipment at both ends along with the OEM reference, length and quantity. Order each compatibility version under its own part number. If spare assemblies are required, list them separately so labels and test records remain unambiguous. This page’s fixed configuration is 15m (49ft); another length must be quoted under its corresponding part number.
Both ends are inspected and the complete assembly is powered up for a functional check before packing. Connectors are protected individually and the cable is secured without tight bends. Optional labels can distinguish host brand, OEM reference and length for easier spares management. Neutral packaging and customer-specific packing documentation are available on request.
No. It is manufactured by HT under our own manufacturer identity.
No. QSFP-DD to QSFP-DD-400G-AOC-15M49FT refers here to 15m (49ft). Every other verified length has a separate part number and page in the length list.
No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.
No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.
