World famous Los Alamos National Laboratory (LANL) in New Mexico, USA has again chosen PPM Test to supply RF over fibre to support their work. LANL have chosen to use multiple DC-coupled links which, unlike AC-coupled links, use 14-bit sampling to digitise the RF signal before transmission over fibre. This digitisation allows point2point DC links to support low frequency ranges.
Los Alamos National Laboratory
Based in New Mexico, Los Alamos National Laboratory (LANL) is a United States Department of Energy laboratory dating from World War II when it was the heart of the famous Manhattan Project that produced the first nuclear weapons. Today, Los Alamos is one of the largest science and technology institutions in the world. It conducts multidisciplinary research in fields such as national security, space exploration, nuclear fusion, renewable energy, medicine, nanotechnology, and supercomputing. LANL is northern New Mexico’s largest institution and the largest employer with approximately 9,000 direct employees and around 650 contractor personnel. Approximately one-third of the technical staff members are physicists, one quarter are engineers and the remainder work in other disciplines including chemistry, material science, mathematics, computational science, biology and geoscience. The annual budget is approximately US$2.2 billion.
point2point links are calibrated, fixed gain RF over fibre links that convert RF signals to the optical domain to allow the transmission over distance, in harsh environments without the interference with the field generated by copper cabling. Typically point2point links are used in applications such as EMC compliance and lightning testing. PPM Test have been manufacturing and supplying RF over fibre links worldwide for almost 25 years.
