megatel MC-FXO-32-SC20A 32CH POTS Over Fiber Converters

megatel-MC-FXO-32-SC20A-32C

Product introduction

MC-FXO-32-SC20A and MC-FXS-32-SC20B are 32CH POTS over fiber converters using the most advanced digital multiplexing communications solutions and fiber optic transmission technology, which can transmit analog and PSTN telephones or Ethernet data signals on a single fiber in real-time synchronization, no distortion, high quality. The plug-and-play design makes installation easy, no need for field settings and adjustment. Please use the FXO unit as a transmitter to connect with PBX analog phone lines and use the FXS unit as a receiver to link with your telephone sets or fax machines. We offer a two-year standard warranty.
