Following a lightning incident back in 2014, I followed the adage that Al, N4ZZ put out about using Fiber in the shack for ethernet connections. I have four fiber lines from the house to the garage/hamshack that replaced two ethernet lines. Each is 111. ft long. Each line carries a grouping of connections such as one for my Flex system, one for my Electraft system, one for Broadcastify and data collection, and the fourth for ‘all other’. I have my network in the shack segregated so that if the Flex system goes out the Elecraft system will hopefully continue. Given that I primarily operate remotely, redundancy in amateur operations is critical because it may be 4-6 weeks between visits to the ham shack that is over 1,280 miles away. I also use fiber as a ‘fire break’ between network switches in the shack and high value equipment such as transceivers. I haven’t found suitable fiber media converters for RS232 or USB. I still have Telco and CATV coax running between the house and shack; it would be nice to find a fiber media converter for those lines as well. I will probably remove them given they are not currently in use.
