Abstract

"MóDULO PARA A TRANSMISSãO DE RáDIO EM FIBRA óPTICA", que consiste em um equipamento desenvolvido para aceitar como entrada, dois canais nas freq³ências de GSM e outros dois canais na freq³ência de DCS, realizando uma conversão eletroóptica dos referidos canais que propagam-se em fibra óptica até a extremidade receptora, no qual realiza-se uma conversão ótico-elétrica e amplifica-se em cada canal até atingir uma potência superior a 0,5 watt em cada um , sendo multiplexados os quatro canais para atingir a antena. No lado de recepção, o canal ou canais que chegam da antena, independentemante da banda que procedem, são convertidos para as freq³ências ópticas, propagadas por fibra e novamente convertidos em freq³ências de radiofreq³ência para serem entregues na Estação Base."MODULE FOR THE TRANSMISSION OF RADIO IN FIBER OPTICS", which consists of equipment developed to accept as input, two channels on the GSM frequencies and two other channels on the DCS frequency, performing an electro-optical conversion of the referred channels that are propagated in optical fiber to the receiving end, in which an optical-electrical conversion is carried out and amplified in each channel until reaching a power greater than 0.5 watt in each one, the four channels being multiplexed to reach the antenna. On the reception side, the channel or channels that arrive from the antenna, regardless of the band they are coming from, are converted to optical frequencies, propagated by fiber and again converted to radio frequency frequencies to be delivered at the Base Station.
