ASFOM FPA Series - Audio Point-to-Point Transmission
The KBC FPA series is part of the ASFOM product family and provides unique, user configurable solutions for audio signals. It supports transmission of up to 128 simplex or 64 duplex audio signals over either one multimode or singlemode optical fibre. Due to the ASFOM flexibility, duplex solutions can either be symmetrical or asymmetrical with respect to the signal quantities. The plug-and-play design ensures ease of installation with no electrical or optical adjustment needed. LED indicators are provided to clearly show the operational status of the unit. Depending on system requirements, units are available in wall-mount, 1U or 2U 19” rack or 3U or 4U chassis card.
