摘要:
A Wavelength Adaptation Module and a method therein for adapting an Optical Time Domain Reflectometry, OTDR, signal for supervision of Optical Network Terminals, ONTs, in a Passive Optical Network, PON, are provided. The wavelength of the OTDR signal is adapted to have a pre-selected wavelength to enable a splitter in a remote node to forward the OTDR signal to a dedicated group of ONTs in the PON, thereby supervising the fibre links between the remote node and the dedicated group of ONTs. Likewise, a remote node and a method therein for receiving an OTDR signal having a pre-selected wavelength from the Wavelength Adaptation Module and for outputting the OTDR signal to a dedicated group of ONTs with regards to the pre-selected wavelength of the received OTDR signal are provided.
摘要(中):
提供了波长适配模块及其中用于适应光时域反射计OTDR信号的方法,用于在无源光网络PON中的光网络终端监控ONT。 OTDR信号的波长适于具有预选波长以使得远程节点中的分路器能够将OTDR信号转发到PON中的专门的ONT组,从而监视远程节点和专用的光纤链路之间的光纤链路 一组ONT。 类似地,一种远程节点及其方法,用于从波长适配模块接收具有预先选择的波长的OTDR信号,并且用于相对于所接收的OTDR信号的预选波长将OTDR信号输出到专用的ONT组 被提供。
