摘要: 光網(wǎng)絡(luò)設(shè)備(Optical Network Terminal,ONT)是XPON網(wǎng)絡(luò)接入方案中的產(chǎn)品,,是一種應(yīng)用在用戶端的光網(wǎng)絡(luò)終端,,有GPON和EPON,。介紹以PON ONU SOC為主控芯片的16線POTS ONT的硬件設(shè)計(jì)及遇到的問題以及如何解決這些問題,。此設(shè)計(jì)是一款基于GPON(ITU-T G.984)標(biāo)準(zhǔn)并支持以太網(wǎng)和語音接口的ONT,,適用于北美市場,,滿足NEBS1標(biāo)準(zhǔn),。本設(shè)計(jì)的特點(diǎn)是有16線的語音用戶接口和1個(gè)GE的接口,,上聯(lián)是GPON,支持Dying Gasp且功耗低,。

Abstract: (Optical network terminal,ONT) is the production of XPON network access.It's an optical network terminal applied at the user end,including EPON (Ethernet Passive Optical Network) and GPON (GigabitCapable Passive Optical Networks)。This paper introduces the design of 16-line POTS with PON ONU SOC as the main control chip,the problems encountered and how to solve them.It is an ONT based on GPON (ITU-T G.984) standard and supports Ethernet and voice interface. It's applicable to north American market and meets with NEBS1 standard.The design features a 16line voice user interface and one GE interface,its uplink is GPON, supports the Dying gasp and has low power consumption.
