OP+OER modules are 3 Gb/s HD-SDI optical-to-electrical receivers. This group of modules is geared toward distributing broadcast signals electrically and optically. They are available in single- and dual-slot versions (the dual-slot version adds a passive splitter and additional reclocked outputs) and in standard-sensitivity PIN and high-sensitivity APD versions.
