 Product Description: 
 OM-S01 Serial Optical 
 OM-S01 Serial Optical (also known as the serial light cat) is the Company pursuant to the power, security monitoring and other industry-specific needs of independent research and development of a serial multi-service transmission equipment. The device serial port (RS232, RS485, RS422, etc.) signal the original signal transmission line in cable into the optical fiber to transmit light signals, which greatly extend the connection distance. With different optical modules, the largest single transmission distance up to 120Km, and optional single-fiber bidirectional optical module, saving valuable fiber resource. OM-S01 1-2 way serial optical transceiver supports full-duplex serial port is completely independent of the transmission, the highest rate> 115.2Kbps. The device uses non-transparent transmission protocol, users will treat it as an extension to the serial signal.
