继续引领光的方向

Keep on Leading Direction of Optical Communication

光通信仍将在未来电信竞争中扮演制高点的角色。运营商建设光网络首先应充分利用光层的技术,提高系统容量,降低系统成本;其次应提供多业务接入平台;最后发展智能光传输网络,增强网络适应能力。北电网络具有优势的城域网络技术集中在三大领域,即城域DWDM、多业务提供平台(MSPP)和弹性分组环(RPR);北电网络OPTera城域系列产品正是在上述技术优势支撑下的产品。

Optical communication will still act as the leading role in the telecom competition in the future.When constructing optical networks,firstly,op erators should make full use of optical lay er tech nology to improve system capacity and de crease system cost,then they should provide multiple-service platform;finally,they should develop in telligent optical transmission network,to increase network adaptability.Nortel Net-works' predomi nant MAN technology main ly con cen trates on3ma jor fields,i.e.DWDM,MSPP and RPR.Nortel Networks' se ries MAN product OPTera is just the product supported by the above technical pre dominance.
