They are not mutually exclusive: silicon-photonics circuits are used inside pluggable transceivers, as well as in newer near-packaged and co-packaged designs. The useful comparison is how optical functions are integrated and packaged—not silicon photonics versus transceivers as though only one can be present.
What each term means
Optical transceiver
A transceiver sits at the end of a fiber link. On transmit, it converts an electrical signal into an optical signal; on receive, it converts light back into an electrical signal. A module may combine optical components such as lasers, photodiodes, and waveguides with electronics and controls. The module’s role is to connect the host device’s electrical interface to the fiber link.
Silicon photonics
Silicon photonics integrates multiple optical functions on a silicon photonic integrated circuit (PIC). STMicroelectronics describes its PIC technology as integrating modulation, waveguides, and photodetection. A complete optical system can still require a light source, electrical ICs, control electronics, and packaging; silicon photonics does not mean every component is made on one silicon chip.
What “traditional” can mean
There is no single architecture or material that defines every traditional transceiver. Optical systems have used materials including gallium arsenide and indium phosphide, and designs vary in how many functions are integrated or kept as separate components. The clearest contrast is between integrating multiple photonic functions on a silicon PIC and using discrete or differently integrated photonic components—not between silicon and one supposedly universal alternative.

Key differences at a glance
| Comparison | Silicon-photonics approach | Discrete or less-integrated optics; pluggable system comparison |
|---|---|---|
| Integration | Multiple photonic functions can share a silicon PIC. | A transceiver may combine separate optical and electronic components; exact designs vary. |
| Manufacturing | Can draw on commercial semiconductor wafer-fabrication infrastructure. Packaging and integration still matter. | Optical manufacturing historically followed a smaller-scale, more bespoke path than the silicon electronics supply chain; that does not describe every current module. |
| Packaging options | Can be used in pluggable modules, near-packaged optics (NPO), or co-packaged optics (CPO). | Pluggable modules are removable front-panel devices; NPO and CPO move optical engines closer to the host processor. |
| Electrical path | Silicon photonics alone does not determine the path. In NPO or CPO, placing the optical engine closer to the processor shortens the electrical interconnect. | A front-panel pluggable generally sits farther from the host ASIC, retaining a modular interface but a longer electrical path. The system-level effect depends on the design. |
| Serviceability | Depends on packaging and fiber attachment. Some advanced packages can use detachable fiber attachment. | Pluggables can be removed and replaced at the front panel. |
| Cost and performance | Potential economies and efficiency benefits depend on implementation and production scale; vendor claims are not universal comparisons. | No neutral, apples-to-apples cost or performance comparison is established by the cited sources. |
Why silicon photonics does not mean CPO
Silicon photonics describes how optical functions are integrated, not where the optical engine is placed in a system. Intel reports silicon-photonics PICs and lasers embedded in pluggable transceiver modules, and Cisco’s white paper specifically addresses silicon photonics in pluggable optics. The same integration approach can also be used in NPO or CPO.
The packaging choices change the balance between modularity and integration. STMicroelectronics describes pluggables as the current approach for scale-out links between servers, racks, and data halls, citing modularity, serviceability, and reach. It describes NPO as placing an optical engine closer to the processor on the host PCB, and CPO as placing it on the same substrate as the processor.

GlobalFoundries says pluggables offer modularity, established standards, and ease of deployment, while CPO can improve bandwidth density and power efficiency by reducing electrical interconnect distance. These are the foundry’s descriptions of the trade-offs, not independent comparative test results. Its platform is described as supporting both pluggable and CPO approaches; the existence of CPO does not make pluggables obsolete.
Capabilities and figures: what the vendor claims establish
- STMicroelectronics PIC100: ST says its platform is designed for 200 Gbps-per-lane PAM4 and supports next-generation 800 Gb/s and 1.6 Tb/s pluggable transceivers. These are stated platform capabilities, not a benchmark against another vendor’s product.
- Intel portfolio: Intel lists 400 Gb/s, 800 Gb/s, and 1.6 Tb/s silicon-photonics solutions. Those portfolio figures do not establish that every silicon-photonics product supports each rate or that the products have identical reach or power characteristics.
- Intel shipments: On its page accessed in 2026, Intel reports shipping more than 8 million PICs and more than 32 million on-chip lasers since 2016, embedded in pluggable transceiver modules. These are Intel-reported shipment totals.
- ST white paper estimates: An approximately 2025 STMicroelectronics white paper states silicon-photonics figures of more than 0.5 Tbps/mm² footprint density, more than 1 Tbps/mm integration density, less than $0.1/Gbps, and less than 5 pJ/bit. These are the paper’s stated advantages, not independent comparative measurements; the paper’s conditions should not be assumed to apply to every implementation.
- Market projection: ST’s current page reports a LightCounting projection that AI-cluster optical technology’s share will rise from 43% in 2024 to 76% in 2030. This is a projection attributed to LightCounting as reported by ST, not a directly checked original study or a measured outcome.
How to choose an architecture
Start with the host platform and link requirements, then decide how much system integration is appropriate. The choice is rarely “silicon photonics or transceiver”; a silicon-photonics pluggable may be one of the options.

- Confirm host compatibility. Check the equipment’s supported module form factors, electrical interface, and vendor compatibility requirements. A PIC technology does not by itself guarantee that a module will work in a given switch or server.
- Specify the link. Match data rate, fiber type, reach, and optical budget to the actual connection. The cited portfolio rates alone do not establish reach or interoperability.
- Set power and cooling limits. Compare the power envelope and thermal requirements of the complete host-and-optics design, rather than treating a vendor’s per-bit or efficiency figure as a universal result.
- Choose the service model. Prefer a pluggable where front-panel replacement and established deployment patterns are priorities. Evaluate NPO or CPO where shorter electrical paths and density are important, while accounting for packaging and fiber-attachment serviceability.
- Compare whole-system evidence. Request implementation-specific data for power, density, reliability, cost, and operating conditions. The vendor figures above do not provide a neutral, same-conditions comparison.
