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
At 1m (3ft), OSFP (RHS/Flat Top) to QSFP-DD-400G-AOC-1M3FT is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.
Position Within the Length Range
OSFP (RHS/Flat Top) to QSFP-DD-400G-AOC-1M3FT is the shortest of 9 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is OSFP (RHS/Flat Top) to QSFP-DD-400G-AOC-2M7FT at 2m (7ft), adding 1m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.
Procurement and Port-Mapping Review
A useful purchase order should identify the host platform, the expected OEM code and the exact cable length as separate pieces of information. This prevents a physically similar assembly from being substituted when the port identification or reach is different. For mixed-length installations, prepare one order line per part number and reconcile each delivered cable with its intended pair of ports. 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.
Generic Compatibility and Factory Testing
Our procurement-oriented compatibility check begins with the OEM reference and ends with a live host link. We record the physical length separately from the identification configuration, so the cable supplied for this page remains the stated version rather than a generic length substitute. The check includes receive activity and diagnostic indications, followed by a final inspection of both ends.
Ordering Information
For a clear bill of materials, quote the OEM reference, HT part number, length and quantity on the same line. Add the switch or server model and software release when a pre-order review is required; project labels can repeat those details for receiving and installation teams. Quantity and any labeling instructions should be attached specifically to OSFP (RHS/Flat Top) to QSFP-DD-400G-AOC-1M3FT.
Quality Assurance and Packaging
Before packing, the assembly is checked for connector condition, identification and link operation. Cables for multi-line orders can be labelled and grouped by part number, making it easier to match each length to the procurement record without opening every protective bag. Neutral packaging and customer-specific packing documentation are available on request.
Frequently Asked Questions
Is this an original equipment manufacturer cable?
No. It is manufactured by HT under our own manufacturer identity.
Will any matching connector operate at the same speed?
Not necessarily. Both hosts must support the stated rate, identification, lane mapping and any required breakout configuration; mechanical compatibility alone is insufficient.
What details assist a compatibility review?
Provide the equipment manufacturer, model, port type, hardware revision and software release, together with the OEM reference, required length and quantity.
How should an unused assembly be stored?
Protect both connector ends, keep the cable in a loose bend-safe coil and retain its part-number label so the length and compatibility identity remain traceable.
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. 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.
