Fibre Optic and RF Transmission

Fibre optic and coaxial connectors are essential components of any modern telecommunications or networking system that needs to transmit signals or data over a long distance. Fibre optic connectors are increasingly popular for their ability to transmit data at high speeds and over long distances. Coaxial connectors, on the other hand, provide a cost-effective and reliable solution for connecting two points in a local area network. Both technologies have their own advantages and disadvantages, and the appropriate choice depends on the specific requirements of their use.

Technical Challenges

Fibre optic connectors principally rely on two technologies: butt joint contacts and expanded beam contacts. Butt joints offer higher optical performance over expanded beam contacts. However, expanded beam contacts offer better resistance to ingress from dirt. As the efficacy of fibre optic connectors depends upon cleanliness at the interfaces, their is a trade off to be made.

The impedance of devices and in transmission lines is a practical problem in radio technology. The characteristic impedance of RF (radio frequency) connectors based on coaxial contacts is 50Ω or 75Ω. 

The Advantages of LEMO Solutions

LEMO provides the best-in-class butt-joint terminals for fibre optic data

The Society for Motion Picture and Television Engineers chooses LEMO as the international standard for camera links. Whether you require single mode, multi mode or large core fibre connections, LEMO offers a wide selection of high quality solutions.

LEMO's wide range of radio frequency (RF) contacts and connectors interface with most cable standards of 50Ω or 75Ω. Our coaxial contacts provide optimal performance at the highest frequencies. Both coaxial contacts and fibre optic terminals can be integrated with other electrical signal types, to create an all-in-one package.
