Experimental investigation on DVB-T over CATV-RoF constraints in long haul Passive Optical Networks

RF phase sensitive amplifier with 70 dB phase sensitive dynamic range

“…The complex electric eld of the RF reference (2) is shown by eqn. (2) and is assumed to have a phase of 0 radians. The RF reference at Ω R is frequency locked to the RF input signal Ω S so that Ω R = Ω S .…”

“…whose second order nonlinearity χ (2) produces a eld component proportional to the square of the electric eld. Ignoring losses, two products and a DC term form: E P 2 = The wanted products are referred to as the idler E i and are shown in the top parentheses of eqn.…”

“…Radio-over-bre (RoF) [1] is an attractive technique to transmit RF signals through bre. RoF can be used for cable television (CATV) distribution networks [2], link base stations to central oces for cellular and mobile data providers, wireless local area networks (WLAN) [3], antenna remoting [4] and signal processing [5]. Compared to coaxial cable, advantages such as very wide bandwidth, low loss, light weight and immunity to RF interference are obtained.…”
