摘要

基于波分复用的无源光网络(WDM-PON)面临各种各样的偶发故障。在wdm - pon中，最好在链路层提供故障管理(生存性)。在本文中，我们的目标是确定可以增加链路层生存能力范围的因素，目前还没有。我们提出了一种具有成本效益的恢复机制，称为ldquoExtended生存性被动接入网(e-SPAN)。e-SPAN是一种多级保护方案，有可能通过在接收端使用不同的前向纠错码来纠正由传输系统引起的最终错误，从而使我们在误码率方面有更好的性能预算，并将传输距离延长至8至12公里。

Extended survivable Passive Access Network (e-SPAN)

Wavelength Division Multiplexed based Passive Optical Networks (WDM-PON) are subjected to wide variety of incidental failures. It is preferred in WDM-PONs to provide fault management (survivability) at link layer level. In this paper, our objective is to determine the factors, which can increase the scope of survivability at link layer, not available currently. We propose a cost-effective recovery mechanism, called ldquoExtended Survivable Passive Access Networkrdquo (e-SPAN). e-SPAN is a multi-level protection scheme that has potential to corrects eventual errors that are caused by the transmission system by using different forward error correcting codes at receiver end, thus allowing us to have better performance budget in terms of BER and extended transmission distance of 8 to 12 Km.
