Specifications

Signal and Lane Configuration

The listed modulation format is OSFP-4x 100G-PAM4QSFP-DD-8x 50G-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.

Integrated Optical Assembly

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.

Length Selection and Installation Planning

Measure twice before deploying this 20m (66ft) cable: once along the planned route and again after accounting for service access. The objective is adequate reach without a concealed surplus. Support the integrated optical cable and both optical engines, preserve front-panel clearance and check that nearby power cords or sharp hardware cannot damage the jacket. Within this family, OSFP (RHS/Flat Top) to QSFP-DD-400G-AOC-15M49FT is shorter at 15m (49ft), while OSFP (RHS/Flat Top) to QSFP-DD-400G-AOC-25M82FT is the next longer choice at 25m (82ft); comparing those two boundaries helps avoid both tension and unnecessary slack.

Position Within the Length Range

OSFP (RHS/Flat Top) to QSFP-DD-400G-AOC-20M66FT occupies the middle of this family between OSFP (RHS/Flat Top) to QSFP-DD-400G-AOC-15M49FT at 15m (49ft) and OSFP (RHS/Flat Top) to QSFP-DD-400G-AOC-25M82FT at 25m (82ft). 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.

Structured Pathways and Serviceability

Treat the direct-attach assembly as part of the permanent pathway plan even when the link is expected to be temporary. Follow the intended horizontal and vertical managers, maintain the specified bend radius and leave service access around both ports. A small, supported service allowance is preferable to excess slack concealed inside a rack or placed under cable-tie pressure. For this assembly, the minimum bend radius is 30mm; the stated power consumption is 14W (OSFP End)10W (QSFP-DD End); the jacket material is OFNP.

Power and Thermal Planning

The rated power consumption is 14W (OSFP End)10W (QSFP-DD 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.

Cable Construction and Routing

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.

Network and Protocol Considerations

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include OSFP MSA, QSFP-DD MSA, CMIS 4.0, IEEE 802.3ck-400GAUI-4, IEEE 802.3bs-400GAUI-8. Confirm that the host firmware and port configuration support the same operating mode.

Ordering Information

Include the part number, fixed length, quantity and required pathway or rack grouping in the order information. The host model and firmware release are useful for change-controlled deployments. Different lengths should remain separate order lines so delivered labels and packing records agree with the pathway plan. Quantity and any labeling instructions should be attached specifically to OSFP (RHS/Flat Top) to QSFP-DD-400G-AOC-20M66FT.

Generic Compatibility and Factory Testing

Verification covers the physical connectors, expected host identity and an operating link with available diagnostic indications. We distinguish this complete check from a simple continuity test. Platform model and software release can be reviewed in advance where the installation has strict documentation or change-control requirements. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.

Shipping and Lead Time

Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. Worldwide courier services are available, with air or sea freight for consolidated shipments; freight-collect delivery and coordination with a customer’s logistics provider can be arranged.

Quality Assurance and Packaging

After connector inspection and link verification, the assembly is coiled without tight bends and packed with end protection. Labels can cross-reference the customer cable schedule, OEM part number and length. This supports both receiving checks and later moves, adds or changes. Standard protective packing is used by default, with project documentation arranged when requested.
