Product Overview

The 400G OSFP to 400G QSFP112 Active Optical Cable (FOT-AOC-400G-OSFP-Q112) is a factory-terminated active optical assembly linking one 400G OSFP port to a QSFP112 port, delivering full 400G throughput over OM3 multimode, 850 nm VCSEL at distances of up to 30 m OM3. Integrated VCSEL transmitters and PIN receivers convert signals to light inside the connector shell, giving fiber-class reach with plug-and-play simplicity — no separate transceivers, patch cords or cleaning required.

Each assembly ships terminated, serialized and 100% traffic-tested: eye-diagram and BER verification on every lane, connector housings inspected, and EEPROM programmed to your requested vendor coding so the cable is recognized natively by your switches and NICs.

An armored variant (FOT-AOC-400G-OSFP-Q112-AR) with an interlocked protective jacket is available for high-traffic raised-floor and overhead-tray routes. OEM branding, custom lengths and mixed-coding ends (different vendor coding on each end) are all supported with short lead times.

Platform Compatibility

Every cable is EEPROM-programmed at the factory to the vendor coding you specify, so it is recognized natively — no "unsupported transceiver" warnings, no console workarounds. Mixed coding (a different vendor on each end) is available for inter-vendor links.

Quality & What's in the Box

100% Traffic Tested

Every lane BER-verified end-to-end on live traffic before packing; eye diagrams sampled per batch.

Serialized & Traceable

Unit serial number links to test record, coding profile and production batch for full traceability.

Test Report Included

Per-order test report available on request; sample reports provided for tender documentation.

Packaging

Individually bagged with pull-tab protector caps, coiled to safe bend radius, export cartons.

Typical Applications

Data Center Fabrics

Spine-leaf and top-of-rack links inside and between adjacent racks.

AI / GPU Clusters

High-radix accelerator fabrics where cost per port and power per bit decide the BOM.

HPC & Storage

InfiniBand-class latency for compute and NVMe-oF storage backends.

Enterprise Core

Cost-effective uplinks between aggregation and core switching layers.

Frequently Asked Questions

AOC vs. two transceivers with a patch cord — which is better?

For point-to-point links up to the AOC's rated reach, the AOC wins on price, power and reliability: the optics are permanently mated and factory-sealed, so there are no connector end-faces to clean and no compatibility guesswork. Choose discrete transceivers when you need structured cabling, patch panels, or field-replaceable ends.

What does the armored version add?

The FOT-AOC-400G-OSFP-Q112-AR variant wraps the same optical assembly in an interlocked armor layer under the LSZH jacket — crush and rodent protection for overhead trays and raised floors, with only a small increase in bend radius and weight.

Will it work with my switch brand?

Yes — tell us your platform when ordering and we program the EEPROM with the matching vendor coding (NVIDIA/Mellanox, Cisco, Arista, Juniper, Huawei, HPE or open MSA). Mixed coding on the two ends is available for inter-vendor links.

What are your MOQ and lead time?

Standard configurations ship in 3–7 days with flexible MOQ. Custom OEM/ODM runs are quoted per project — send us your specs for a fast quotation.
