Implementing a PON test strategy
Test Strategy for characterizing connectorized passive optical
networks
For a PON network, different opinions exist regarding the need
whether to connectorize the elements along the link or splice
directly to splitters, terminals, and the CPE. Using connectors adds
loss along the network but enables easy evolution of the network
and provides more test access points. This chapter describes the
deployment stages of fully connectorized networks only. Specific
paragraphs detail the test procedure differences when other
networks principles are used.
