The 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top)-800G-DAC-1.5M5FT cable offers a direct 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) connection at 800Gbps. Its 1.5m (5ft) length and DAC construction are intended for multi-vendor equipment, with no separate transceiver-and-patch-cord assembly required.

• Minimum bend radius: 40.5mm

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.

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.

This assembly uses 28AWG conductors, PVC jacket, minimum bend radius 40.5mm. 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 determined by the host interface and protocol support. Listed interface and protocol references include OSFP MSA, IEEE 802.3ck, CMIS v4.0. Confirm that the host firmware and port configuration support the same operating mode.

The 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned 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.

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.

The additional half metre beyond a one-metre assembly gives 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top)-800G-DAC-1.5M5FT useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top)-800G-DAC-1.5M5FT is the longest of 3 verified length options in this family. Compared with 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top)-800G-DAC-1M3FT at 1m (3ft), it provides 0.5m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

Each 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top)-800G-DAC-1.5M5FT compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Generic platform should be included with the order.

Quote HT part number 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top)-800G-DAC-1.5M5FT with the required quantity. The 1.5m (5ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
