Wide band optical fiber access network trend of development
This article first is brief introduced the world broadband access network develops the condition and the main application, next narrated the wide band optical fiber access network merit. With emphasis has once more analyzed the wide band point-to-point active Ethernet optical fiber system and the wide band to the passive optical fiber system characteristic and the application. Meets down proposed our country optical fiber access network sends chem. possible to surmount APON, BPON and the EPON stage, starts from the wide band point-to-point Ethernet optical fiber system and GEPON, finally and even transits to the GPON stage preliminary idea. Finally analyzed the optical fiber communications technology trend of development from each angle.
寬帶光纖接入網(wǎng)的發(fā)展趨勢
本文首先簡要介紹世界寬帶接入網(wǎng)發(fā)展的狀況和主要應(yīng)用；其次講述了寬帶光纖接入網(wǎng)的優(yōu)點(diǎn)；再次重點(diǎn)分析了寬帶點(diǎn)到點(diǎn)有源以太網(wǎng)光纖系統(tǒng)和寬帶點(diǎn)到多無源光纖系統(tǒng)的特點(diǎn)和應(yīng)用。接下來提出我國光纖接入網(wǎng)的發(fā)展可能跨越
APON、BPON和EPON階段，從寬帶點(diǎn)到點(diǎn)以太網(wǎng)光纖系統(tǒng)和GEPON開始，乃至最終過渡到GPON階段的初步設(shè)想。最后從各個角度剖析了光纖通信技術(shù)的發(fā)展趨勢。
