FD7944N
All-In-One-CD7944N EOC

Name: FD7944N
Brand: Shenzhen C-Data Technology Co., Ltd.

O produto C-Data All-In-One foi projetado para fornecer serviço de Internet para a casa do assinante por meio da rede de acesso coaxial existente. Com a tecnologia XPON, EOC e HFC, o produto All-In-One atende aos requisitos de transmissão CATV, VOD e serviço de Internet das operadoras de cabo para FTTB/FTTC. Ele foi construído com módulo XPON ONU, mestre EOC e receptor óptico em um único alojamento.

O módulo receptor óptico recebeu o sinal óptico do transmissor óptico da rede HFC e o sinal processado pelo PD, amplificador, EQ e AGC para uma saída de RF estável. O nível de saída será de até 104dBuv (saída 4 * RF). Os dados Ethernet são entregues à ONU por meio da rede XPON do OLT.

O módulo EOC Master atende aos padrões AV de plugue doméstico, é projetado com base no conjunto de chips Qualcomm AR7410 com alta tecnologia OFDM de capacidade anti-interferência. Ele irá modular os dados Ethernet em sinal de RF EOC em 7,5-65MHz. O sinal EOC e o sinal CATV (87 ~ 860MHz) podem funcionar em um cabo coaxial sem interferência. O EOC Master pode fornecer serviço de dados de alta velocidade a 600Mbps de velocidade da camada PHY, a taxa de transferência da camada MAC é de até 320Mpbs.
