VERSITRON offers installation kits for extending 1 to 8 Plain Old Telephone Service (POTS) analog phone lines using fiber converters. Voice links are then secure and free from EMI/RFI interference, lightning, and ground loops.
The FXO unit is installed at the PBX site (exchange) and the FXS unit is installed at the telephone site (subscriber). Note: For "ring down" applications FXS units are installed at both ends of the link.
The FXO side of the link accepts a telephone audio signal on its RJ11 connector from the exchange, and digitizes it with an analog-to-digital converter. Each of the digital samples is then encoded and applied to the SFP module for transmission over the fiber optic cable.
The FXS unit decodes the signal from the SFP module and applies it to a digital-to-analog converter to recover the analog audio. The converse occurs in the other direction for the FXO device. The telephone modem transmits analog signals of 300 to 3400Hz.
Kits are also offered that support an independent and balanced RS-485/RS-422 data link up to 64Kbps on the RJ-45 connector for transmission across the fiber optic line. This interface is full duplex only.
