Dangers of ungrounded optical receivers
The optical receiver converts power fluctuations into current fluctuations which add to those resulting from shot noise and thermal noise. An exact analysis is complicated, as it involves the calculation of photocurrent. When an RF current is supplied to an antenna, an electromagnetic field is create that is able to travel, or spread through space. In particular, the analysis assumes that the optical signal incident on the receiver consists of an ideal bit stream such that 1 bits consist of an optical pulse of constant. Public safety voice and data communications are continuously at risk of radio frequency (RF) interference, which is defined as "the effect of unwanted energy due to one or a combination of emissions, radiations, or inductions upon reception in a radio communication system, manifested by any.
