As redes \u00f3pticas s\u00e3o atualmente a melhor alternativa para obter altas taxas de transmiss\u00e3o de dados em m\u00e9dias e longas dist\u00e2ncias. Hoje existem links de comunica\u00e7\u00e3o por fibra \u00f3ptica que ultrapassam a casa dos Gbps, com extens\u00f5es de dezenas ou mesmo centenas de quil\u00f4metros. Para tornar poss\u00edvel essa transmiss\u00e3o \u00e9 preciso adequar o sinal dos equipamentos eletr\u00f4nicos ao meio de transmiss\u00e3o e esse papel \u00e9 realizado pelo transceptor \u00f3ptico.<\/span><\/span><\/p>\n

Um transceptor \u00f3ptico, ou simplesmente transceiver, \u00e9 um dispositivo que combina transmissor e receptor \u00f3ptico num s\u00f3 dispositivo eletr\u00f4nico. O transceiver transforma os sinais \u00f3pticos recebidos atrav\u00e9s do cabo em sinais el\u00e9tricos que s\u00e3o enviados aos equipamentos eletr\u00f4nicos e vice-versa. Estes m\u00f3dulos fazem parte dos equipamentos ativos na rede \u00f3ptica e est\u00e3o dispon\u00edveis em diferentes modelos padr\u00e3o. Alguns modelos mais comuns de transceptores em redes \u00f3pticas:<\/span><\/span><\/p>\n

Os transceptores para fibra \u00f3ptica mais usados em redes passivas s\u00e3o a unidade externa plug\u00e1vel SFP (Small Form-factor Pluggable), para inser\u00e7\u00e3o no equipamento e a unidade interna, SFF (Small Form Factor), fixado diretamente na placa eletr\u00f4nica do equipamento. Uma das principais caracter\u00edsticas dos m\u00f3dulos SFP \u00e9 que eles podem ser inseridos ou retirados sem desligar a alimenta\u00e7\u00e3o do equipamento de rede (s\u00e3o ditos hot-plugable). <\/span><\/span><\/p>\n

<\/a> Os transceivers \u00f3pticos s\u00e3o componentes utilizados em conjunto com as portas \u00f3pticas PON e com as placas de uplink de OLT’s EPON ou GPON, atuando como moduladores\/demoduladores \u00f3pticos para realizar a convers\u00e3o \u00f3ptico\/el\u00e9trica em redes PON e possibilitar o tr\u00e1fego de dados em redes \u00f3pticas entre o switch e a plataformas PON. Por exemplo, um SFP \u00e9 utilizado em conjunto com o OLT para possibilitar a interface \u00f3ptica deste equipamento com a rede de fibra, seguindo um padr\u00e3o de especifica\u00e7\u00e3o de classe de laser que indica a pot\u00eancia na qual o equipamento dever\u00e1 funcionar.<\/span><\/span><\/p>\n
