PBX-AF-100
PROBOX family optical converter for transporting audio, RS232/422/GPIO data and intercom.
PRODUCT OVERVIEW
ProBox series PBX-AF-100 optical converters are intended for transporting of up to eight channels of audio (analog and/or AES), an InterCom bidirectional channel, two RS-232/422 data channels and GPIO commands over a single optical fiber. Data-only modifications available.
- Up to eight audio channels + RS232/422 data + GPIO over a single optical fiber
- Analog line, microphone(+48V phantom powered) and/or AES/EBU inputs/outputs (by request)
- Input/output autoconfiguration by the SFP type inserted: Rx, Tx, Rx+Tx
- Front panel controls: input/output gain, audio channel re-mapper, input signal invertion, selected audio pair headphone monitor
- InterCom channel with 3.5mm jack headphone+mic connector
- Two port RS-232/RS-422, 4 GPI, 4 GPO data
- Four-channel GPIO in each direction
- Input/Output optical power and wavelength monitoring
- 1310nm, 1550nm, CWDM or DWDM wavelength capability
- Up to 140 km transmission distance
- Compact cases
