BF4 – Hirose’s Unidirectional Active Optical Connector System

Hirose, a leader in the design and manufacture of innovative connector solutions, has developed a unidirectional active optical connector system with built-in E/O on the Tx (transmit) end and an O/E on the Rx (receiver) end. The BF4M optical connector system converts a balanced high-speed differential electrical signal on a PCB at one end into a MM optical signal for transmission down a very thin flexible FO cable, and then converts it back into an electrical signal on the other end. The BF4M Series is designed as a separate plug and receptacle that solders to the PCB to eliminate the thermal issues associated with soldering the E/O and O/E devices directly to the PCB.
