Enlace óptico RF+FI. Receptor (RX)
El sistema RF Optical Link ha sido diseñado para permitir que la polaridad de un satélite con FM, DAB y DTT se distribuya en una sola fibra.
Enlace simple sobre fibra
- PSU única para varios transmisores
- Económico
- Alcance de 10 km
El sistema RF Optical Link ha sido diseñado para permitir que la polaridad de un satélite con FM, DAB y DTT se distribuya en una sola fibra.
La unidad RF Optical Link RX se conecta a la unidad TX cuando envía las señales de satélite, TDT y DAB sobre una polaridad a varias ubicaciones.
