Specifications

Signal and Lane Configuration

The listed modulation format is OSFP-8x 100G-PAM4QSFP112-4x 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.

Length Selection and Installation Planning

OSFP (IHS/Finned Top) to 2x QSFP112-800G-DAC-2M7FT provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

Position Within the Length Range

OSFP (IHS/Finned Top) to 2x QSFP112-800G-DAC-2M7FT is the longest of 4 verified length options in this family. Compared with OSFP (IHS/Finned Top) to 2x QSFP112-800G-DAC-1.5M5FT at 1.5m (5ft), 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.

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 28AWG; the minimum bend radius is 40.5mm; the stated power consumption is 0.1W (OSFP End)0.1W (QSFP112 Per End); the jacket material is PVC.

Power and Thermal Planning

The rated power consumption is 0.1W (OSFP End)0.1W (QSFP112 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 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.

Network and Protocol Considerations

The intended application is 800G/400G Ethernet. Listed interface and protocol references include OSFP MSA, QSFP112 MSA, IEEE 802.3ck, CMIS v5.0. Confirm that the host firmware and port configuration support the same operating mode.

Breakout Port Mapping

The OSFP (IHS/Finned Top) to 2x QSFP112 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.

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. Where supported by the host, link stability and diagnostic indications are reviewed together with the established link.

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. This page’s fixed configuration is 2m (7ft); another length must be quoted under its corresponding part number.

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

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.
