In order to use existing optical MOST150 tools/devices also in systems that are based on a coax electrical physical layer (cPHY), the MOST150 C-O Converter can be integrated into the coaxial network. The optical MOST150 tools/devices can then be connected to the optical interface of the MOST150 C-O Converter using the delivered optical MOST cable. The MOST150 C-O Converter indicates both ‘power is connected’ and ‘MOST signal is detected’. The MOST150 C-O Converter is available in two flavours - a simplex variant and a duplex variant. The simplex variant is suitable for simplex cPHY networks, the duplex variant can be used in duplex cPHY networks. As it is equipped with one coax interface, the latter supports the so called end-point use case (communication between one MOST150 coax duplex device and one MOST150 optical device/tool). Please consider that the MOST150 C-O Converter is not qualified for automotive applications.
