OSFP (IHS/Finned Top) to 4x QSFP28-400G-AOC-5M16FT 400G OSFP 8 x 50G PAM4 IHS/Finned Top to 4 x 100G QSFP28 4 x 25G NRZ Active Optical Breakout Cable, 5m (16ft)

The OSFP (IHS/Finned Top) to 4x QSFP28-400G-AOC-5M16FT cable offers a direct OSFP (IHS/Finned Top) to 4x QSFP28 connection at 400Gbps. Its 5m (16ft) length and AOC construction are intended for multi-vendor equipment, with no separate transceiver-and-patch-cord assembly required.

The listed modulation format is 8x 50G-PAM4 to Quad 4x 25G-NRZ. 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 intended application is determined by the host interface and protocol support. Listed interface and protocol references include CMIS 4.0, SFF-8636，IEEE 802.3bs-400GAUI-8, IEEE802.3bm-CAUI-4, OSFP MSA, SFF-8661, SFF-8639. Confirm that the host firmware and port configuration support the same operating mode.

The OSFP (IHS/Finned Top) to 4x QSFP28 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.

The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.

The 5m (16ft) length gives OSFP (IHS/Finned Top) to 4x QSFP28-400G-AOC-5M16FT more freedom for adjacent-rack and row-end deployments. The integrated optical assembly should be supported along its route without tight bends or connector pull loads; the AOC specification and host support must still match the intended link.

The rated power consumption is 10W (OSFP End) 5.5W (QSFP28 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 OFNP jacket, minimum bend radius 30mm. 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 assembly is configured for equipment that recognizes OSFP (IHS/Finned Top) to 4x QSFP28-400G-AOC-5M16FT. Before shipment, we inspect both connectors and verify identification, link establishment and optical link operation, receive activity and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

When ordering, specify OSFP (IHS/Finned Top) to 4x QSFP28-400G-AOC-5M16FT, cable length 5m (16ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

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 (IHS/Finned Top) to 4x QSFP28-400G-AOC-5M16FT and the 5m (16ft) length for easier inventory control.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
