Expanded beam fiber optic connector technology

Bulgin, a manufacturer of environmentally sealed connectors and components, has launched a patented (UK and USA) expanded beam fiber optic connector and cable management system. The technology, which is now available in the 5000 Series Expanded Beam Connector, is the result of a two-year project to produce a low-cost, sustainable expanded beam product suitable for a wide range of industries.

Expanded beam fiber optic connectors are typically used in applications where it is important to reduce the impact of dirt or contamination when joining two fiber optic cables. Accurate alignment of ferrules and minimal twisting of fiber optic cables are critical to minimize light loss and to ensure efficient transmission of the signal through the connector.

Bulgin's patented technology offers a ferrule-lens alignment technology in combination with a cable management system to prevent twisting of the optical fibers. This solution allows the rapid termination and repair of cables in the field, making the 5000 Series Expanded Beam Connector suitable for harsh environment applications, including military communications, mining, oil and gas, and broadcasting. It is particularly suited to temporary fiber optic set-ups that need to be quickly assembled and dismantled, such as concert venues and sports stadiums.

Thisen Bird, associate product manager at Bulgin, said, We have successfully developed a redeployable synthetic polymer connector system that offers the same robust level of performance as traditional military standard connectors, but at a lower cost. This project shows what can be achieved when a knowledgeable team is given the freedom to innovate.

Jose Latre, lead development engineer at Bulgin, continued, This was a very rewarding project, culminating in a patented product that meets the demands of any industry needing quick deployment of fiber optic systems in harsh environments. It opens up the use of expanded beam technology to applications where the price of previous products may have been prohibitive, without compromising on the high level of reliable signal transmission that these users require.

Bulgin manufactures a range of rugged connectors, fuse holders, battery holders, switches and indicators designed for use in challenging environments. Headquartered in Cambridge, UK, the company has offices in key global regions and a sales and distribution network covering 65 countries. Its manufacturing facilities are based in the UK and Tunisia.
