OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-DAC-2M7FT 400G OSFP 4 x 100G PAM4 RHS/Flat Top Passive Copper Twinax Cable, 2m (7ft)

For short, high-density connections, this DAC cable combines 400G performance with a fixed 2m (7ft) cable run. It corresponds to Generic OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-DAC-2M7FT and uses a factory-terminated passive copper link without separate optical modules or patch cords.

The listed modulation format is 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.

OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-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.

OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-DAC-2M7FT is the longest of 4 verified length options in this family. Compared with OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-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.

The rated power consumption is 0.1W. 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 (OFNR) 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, CMIS Rev4.0, IEEE 802.3cd. Confirm that the host firmware and port configuration support the same operating mode.

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.

Our compatibility setup for Generic OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-DAC-2M7FT is checked together with the physical 2m (7ft) assembly. Factory verification covers connector condition, host identification, error-free link establishment and electrical continuity, link stability and diagnostic readouts. Providing the exact host model and firmware release helps us identify platform-specific requirements before production.

Quote HT part number OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-DAC-2M7FT with the required quantity. The 2m (7ft) 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.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-DAC-2M7FT and the 2m (7ft) length for easier inventory control.

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.
