Question about link power budget
Posted: 26 Feb 2022 05:26 AM PST
https://www.reddit.com/r/amateurradio/comments/t1x2eh/question_about_link_power_budget/
A digital fiber link of overall length of 10km operates at 20Mbps has the following components: A. LED that is capable of launching an average power
of 0.1uW at 85um B. Fiber Attenuatiin of 2.5dB/km C. Requires splicing
every 2 km with a loss of 0.3dB per slice D. Connector loss is 1.5dB E. The received power needed is -46dBm in order to get 10-10 BER F. Predicted
safety margin js 6dB Find the link power budget
So what is the proper formula since in the splicing loss, some does
length/2km x splice loss then some does ((length/2km)-1) x splice loss and
then theres the connector loss where some does it as is 1.5dB then others multiply is by 2. Wha is the proper/correct formula for it? Ty submitted

Question about an extension cable

https://www.reddit.com/r/amateurradio/comments/t1v8k1/question_about_an_extension_cable/
I have an uv-5r mounted on my plate carrier and and abree antenna on my backpack, with an extension cable running between the two. Since i want to easily detach my radio, I wanted to solder a BNC connector on the cable
close to the radio, and to put a sleeve on in. Will a conductive
sleeve(shield) help me cut out interference or do i just put a normal nylon sleeve around it? submitted by /u/illshowyouicancum
