TE Connectivity is investing more than $60 million in a new optical research and manufacturing facility in New York State, expanding its capacity to produce high-density fibre connections for advanced data centre equipment.
The 135,000 sq ft facility will be established in Henrietta, near Rochester, and will develop fibre array units using technology recently acquired from RAM Photonics. TE expects the site to open in spring 2027, with manufacturing capacity increasing progressively through 2031.
The company plans to employ more than 800 people across engineering, manufacturing, and management functions in the greater Rochester region. Announced on 12 November 2026, the project extends TE's optical connectivity activities alongside its established portfolio of electrical connectors and interconnect components.
Fibre array units provide a mechanical and optical interface between multiple optical fibres and the devices responsible for transmitting or receiving light. Their construction must maintain precise alignment between individual fibres and the corresponding optical channels, allowing signals to pass through the connection with sufficiently low optical loss.
The requirements become more demanding as channel counts increase and the available space around each optical connection decreases. Small positional errors can reduce coupling efficiency, while variations in materials, component dimensions, and assembly processes can introduce differences between nominally identical channels.
TE's investment is directed towards these high-density fibre attachment requirements, particularly those associated with co-packaged optics. The technology places optical communication functions close to electronic switching or processing silicon, reducing the length of some high-speed electrical signal paths within computing equipment.
Conventional data centre equipment often connects processing or networking devices to optical transceiver modules through electrical traces and connectors. As data rates increase, those electrical paths become more sensitive to attenuation, reflections, crosstalk, and other signal integrity effects.
Maintaining acceptable signal quality can require increasingly sophisticated equalisation and conditioning circuitry. These functions consume electrical power and occupy circuit-board resources, particularly where large numbers of high-speed connections must operate simultaneously.
Co-packaged optics seeks to reduce those electrical path lengths by bringing optical interfaces closer to the principal processing devices. Fibre connections then become an essential part of the physical assembly, requiring high channel density and repeatable optical alignment within a restricted mechanical envelope.
The fibre array unit does not replace the optical transmitter, receiver, or electronic processor. It provides the interface through which multiple optical channels can be connected to those components, with its geometry and alignment influencing the losses encountered at the connection.
Increasing connection density requires careful control of fibre spacing, placement, and the structures used to hold the fibres in position. Manufacturing processes must produce consistent geometries while accommodating the tolerances of the optical devices and surrounding package.
Thermal and mechanical conditions add further constraints. Materials within an optical assembly can expand at different rates as operating temperatures change, potentially shifting the relative position of optical components. Handling, installation, and repeated thermal cycling can also affect an interface that relies on precise alignment.
The manufacturing challenge consequently extends beyond producing fibre assemblies with the required dimensions. Inspection and testing must establish whether each assembly maintains acceptable optical characteristics and whether those characteristics remain stable under the intended operating conditions.
Production scale places another demand on the process. An assembly method that produces acceptable prototypes must also support repeatable results at the volumes required by customers, with appropriate controls over alignment, yield, and inspection time.
TE has not disclosed the complete manufacturing process planned for Henrietta or the production capacity associated with the investment. The new facility will combine research and development with manufacturing, supporting the further development of the fibre array technology and its introduction into customer programmes.
The company identifies hyperscale AI data centre operators and cloud providers as the intended market. Increasing accelerator and networking capacity creates demand for greater communication bandwidth between computing components, although the appropriate interconnect arrangement depends on distance, power consumption, cost, and the architecture of the complete system.
Optical transmission offers a means of carrying high-speed data without relying on copper for the entire connection. It nevertheless introduces its own electrical and optical conversion requirements, including light sources, detectors, associated circuitry, and mechanical interfaces.
The energy and density characteristics of a particular co-packaged optical arrangement must therefore be evaluated at system level. Reducing losses in one part of the connection does not automatically establish lower total power consumption once the complete optical and electronic architecture is considered.
TE's acquisition of RAM Photonics technology provides the manufacturing foundation for the fibre array work. The Henrietta site will expand the company's engineering and production capacity for these components rather than representing the introduction of a complete optical transceiver or computing platform.
Terrence Curtin, chief executive of TE Connectivity, identified growing customer interest in optical connectivity as a reason for the investment. The company expects the additional engineering and manufacturing capacity to support design awards and subsequent production growth.
Its announcement does not identify individual customer contracts, annual production volumes, or measured optical insertion-loss improvements attributable to the planned facility. Those figures will depend on the products developed and the manufacturing processes ultimately established at the site.
The project will also expand TE's presence within the Rochester region, which has an established optical technology and manufacturing sector. The company expects the new facility to support engineering, production, and management employment as operations develop over the coming years.
The first scheduled milestone is the opening in spring 2027. Manufacturing expansion will continue through 2031, with the new operation intended to support high-density fibre attachment requirements as customers develop and qualify their optical interconnect architectures.
