For buyers working from an equipment parts list, OSFP (IHS/Finned Top) to 2x OSFP (RHS/Flat Top)-800G-DAC-0.5M2FT identifies more than a connector style. It refers here to a 0.5m (2ft) DAC cable for Generic hosts, supporting 800G operation with OSFP (IHS/Finned Top) to 2x OSFP (RHS/Flat Top). The sections below separate the OEM cross-reference, physical specification and HT factory checks for straightforward purchasing review.

Signal and Lane Configuration
The listed modulation format is 8x 100G-PAM4 to Dual 4x 100G-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.
Position Within the Length Range
OSFP (IHS/Finned Top) to 2x OSFP (RHS/Flat Top)-800G-DAC-0.5M2FT is the shortest of 5 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 (IHS/Finned Top) to 2x OSFP (RHS/Flat Top)-800G-DAC-1M3FT at 1m (3ft), adding 0.5m 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 listed conductor specification is 30AWG; the minimum bend radius is 58mm; the stated power consumption is 0.1W (800G End)0.1W (400G Per End); the jacket material is PET.
Power and Thermal Planning
The rated power consumption is 0.1W (800G End)0.1W (400G 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.
Cable Construction and Routing
This assembly uses 30AWG conductors, PET jacket, minimum bend radius 58mm. 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 800G/400G Ethernet. Listed interface and protocol references include OSFP MSA Rev5.0, IEEE 802.3ck, CMIS 4.0. Confirm that the host firmware and port configuration support the same operating mode.
Breakout Port Mapping
The OSFP (IHS/Finned Top) to 2x OSFP (RHS/Flat Top) 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.
Passive Copper Operation
A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.
Length Selection and Installation Planning
The 0.5m (2ft) length is suited to closely aligned ports where excessive slack would obstruct airflow or complicate dressing. Measure the actual port-to-port path before choosing OSFP (IHS/Finned Top) to 2x OSFP (RHS/Flat Top)-800G-DAC-0.5M2FT; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.
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. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.
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 (IHS/Finned Top) to 2x OSFP (RHS/Flat Top)-800G-DAC-0.5M2FT.
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. Volume orders can include customer references on the labels and carton list.
Frequently Asked Questions
Is this an original equipment manufacturer cable?
No. It is manufactured by HT under our own manufacturer identity.
Can different brands be connected with the same assembly?
Only where both hosts explicitly support the complete interface and compatibility arrangement. Document each end and select the appropriate brand-specific product when required.
Does this order code cover multiple lengths?
No. OSFP (IHS/Finned Top) to 2x OSFP (RHS/Flat Top)-800G-DAC-0.5M2FT refers here to 0.5m (2ft). Every other verified length has a separate part number and page in the length list.
Are separate transceivers or patch leads required?
No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. 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.
