The OptiQwave 8780 is a new generation point-to-point digital microwave system that provides STM-1 optical or electrical fiber-like transmission quality with reaching distance up to 80 Km.

The OptiQwave 8780 is equipped with the industrial leading edge modular design. The individual module in the system is hot-swappable when the system is in service running, which eliminate the out of service period when module replacement is necessary.

The high integrated system design supports either space and frequency protection mode or (1+1) protection mode, which offers the carrier flexible network protection strategy.

Thanks to the sophisticated hardware and software technology, The OptiQwave 8780 offers the unprecedented performance on co-channel and adjacent channel interference immunity, superb system gain with advanced FEC (Forward Error Correction) algorithm and the multi-path fading problem is efficiently alleviated with a high performance DFE adaptive equalizer.

(1+0) Space Diversity Application:

Multi-path microwave interference problem takes place in some particular environment, which seriously affects the radio communication quality. The OptiQwave 8700 and 8780 series solve this issue and get excellent performance by offering the space diversity scheme integrated in the system already.

Thanks to the flexible protection switch scheme of OptiQwave 87xx series, space and frequency diversity or (1+1) hot standby protection switch is provided to offer reliable and secure communication quality.
