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.

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

OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-DAC-1.5M5FT occupies the middle of this family between OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-DAC-1M3FT at 1m (3ft) and OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-DAC-2M7FT at 2m (7ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

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.

For this Generic application, testing combines digital identification with actual traffic-link verification and electrical continuity, link stability and diagnostic readouts. Both ends are inspected for latch, boot and connector damage. If the project uses a specific hardware revision or a channelized port, send those details so that the intended configuration can be reviewed before shipment.

Quote HT part number OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)-400G-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.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

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.
