J3U N+1 Redundancy

Many redundant signal architectures may be constructed in Optical Zonu’s J3U chassis platform. 1+1 architectures are common, however as a spare transmitter/receiver pair are required for each primary transmitter/receiver pair, the cost and rack space required by such a redundant system may become prohibitive. N+1 architectures require a spare transmitter/receiver pair for each N transmitter/receiver…

Optical Links

There are many benefits to using optical links, in place of waveguide and coaxial cable, for the transport of RF signals. In situations where equipment (antennas, satcom modems, etc.) are separated by long distances (> 100 meters), optical links provide low loss signal transport (~ 0.7 dB/km RF attenuation). Unlike copper, this fiber attenuation is…
