The 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (RHS/Flat Top)-800G-ACC-4M13FT compatible cable combines 800G ACC connectivity with a defined 4m (13ft) pathway between 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (RHS/Flat Top) interfaces. It is intended for Generic equipment and is documented here as a distinct order code, allowing cable schedules, service access and related length selections to be reviewed before installation.

Signal and Lane Configuration
The listed modulation format is 8x 100G-PAM4 to Dual 4x 100G-PMA4. 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.
Network and Protocol Considerations
The intended application is 800G/400G Ethernet. Listed interface and protocol references include OSFP MSA, CMIS 5.0, IEEE 802.3 ck. Confirm that the host firmware and port configuration support the same operating mode.
Breakout Port Mapping
The 800G OSFP (IHS/Finned Top) to 2x 400G 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.
Length Selection and Installation Planning
The 4m (13ft) length gives 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (RHS/Flat Top)-800G-ACC-4M13FT more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the ACC specification and host support must still match the intended link.
Position Within the Length Range
800G OSFP (IHS/Finned Top) to 2x 400G OSFP (RHS/Flat Top)-800G-ACC-4M13FT occupies the middle of this family between 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (RHS/Flat Top)-800G-ACC-3M10FT at 3m (10ft) and 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (RHS/Flat Top)-800G-ACC-5M16FT at 5m (16ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 1m. 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 listed conductor specification is 26AWG; the minimum bend radius is 40mm; the stated power consumption is 1.5W (800G End)/0.6W (400G Per End); the jacket material is PET.
Power and Thermal Planning
The rated power consumption is 1.5W (800G End)/0.6W (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 26AWG conductors, PET jacket, minimum bend radius 40mm. 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.
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. Keep 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (RHS/Flat Top)-800G-ACC-4M13FT associated with 4m (13ft) throughout the order and receiving record.
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 link stability 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. 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.
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.
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. 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (RHS/Flat Top)-800G-ACC-4M13FT refers here to 4m (13ft). Every other verified length has a separate part number and page in the length list.
