Beyond Pluggables: On-Board and Co-Packaged Optics

Not every link belongs on the faceplate. The LEAP® On-Board Transceiver is a rugged 12-channel duplex module running up to 25 Gb/s per channel — 300 Gb/s cumulative — in roughly one square inch of board space at 5.4 W. That is about 2.5× less board area than a 12-channel QSFP28 arrangement, and the optical cable can be routed above or around other components in the design.

Further in, Amphenol’s co-packaged optics extend ownership all the way to the chip: the high-density electrical interposer, the linear optical conversion inside the module, and the fiber plant beyond. Where other suppliers offer a module, this is an architecture — pluggable, modular, and qualified across the whole signal path by one supplier.

Applications

AI Training & Inference Clusters

Scale-up and scale-out fabrics where per-lane rate, latency and watts per bit decide how far a cluster can grow.

Engineering and Manufacturing Capabilities

Amphenol is US headquartered with full manufacturing capability in China and Taiwan, and experienced global R&D and engineering teams in the US, Germany and China. Optical packaging design and manufacturing, including TOSA and ROSA, is done in-house and tested in mainland China and Taiwan.

Manufacturing runs across 5,000 square metres of clean room space in Shenzhen, Taiwan and Berlin, with capacity for 8,000,000 modules. A low cost manufacturing footprint and flexible supply chain keep the cost model competitive, and a large quality team runs the fully transparent quality systems these markets demand.

Amphenol also plays an active role in MSA committees and works closely with the standards bodies — OIF, IEEE 802.3, the Advanced Photonics Coalition, LPO MSA, PCI-SIG, FCIA, IBTA, SNIA, STA and INCITS T10/T11 — that shape the next generation of optical systems.

Frequently Asked Questions

LPO removes the DSP from the optical module and drives the link linearly from the host ASIC. That cuts power and latency, which is what limits how far an AI fabric can scale. An XPO-LPO module delivers 12.8 Tb/s for 80 W total, and Amphenol’s 800G OSFP LPO modules run under 8.5 W, typically 7.5 W.

XPO-LPO addresses the power and density wall that traditional OSFP form factors cannot cross. It carries 64 high-speed lanes at 224 Gb/s each — 12.8 Tb/s from one module against 800 Gb/s to 1.6 Tb/s from an OSFP module — and is engineered for liquid cooling rather than air.

Data rates from 12G to 1.6T, supporting Ethernet, Fibre Channel, InfiniBand, SAS, PCIe and CPRI. Optical reach options span SR, LR, ER and ZR, from 100 m to 120 km, using BIDI, DWDM, LWDM and tunable CWDM technologies.

Copper is the cheaper, lower-power choice at short reach — 112G passive assemblies run to about 2 m and active to about 4 m. Beyond that, active optical cables carry the link: 100 m over multimode fiber for both the 100G QSFP28 and 200G QSFP-DD AOCs, at low weight and low power.

Yes. The OSFP-RHS 224G cold plate and cage assembly integrates cold plates into the cage itself, dissipating more than 40 W per module across up to 16 ports in series. XPO-LPO is likewise engineered for liquid cooling in hyperscale AI racks.

Yes — that vertical integration is the point. Front panel I/O connectors and cages, bulk cable design and manufacturing, passive and active I/O cable assemblies, AOCs and transceivers all come from one supplier, so the whole signal path is qualified together.

Yes. Whether the requirement is an industry standard part or an application specific design, Amphenol’s engineering teams support custom configurations, lengths and terminations. Contact us with your requirements.
