@Collins just as you would imagine...total signal loss akin to a fiber cut. :)<div><br></div><div>Over distance FSO and 24GHz backhauls are susceptible to attenuation from rain, more so the former. Even bad fog can really throttle down FSO throughput.</div>

<div><br></div><div>FSO links still exist, given my visits to many rooftops around Nairobi as others may also attest...but I don&#39;t know if they are operational. They may be backups just in case someone cuts the fiber...most users are GSM operators.</div>
