  • Monitoring packet loss at optical splitter switches

    Monitoring packet loss at optical splitter switches

    Testing a splitter or other passive fiber optic devices like switches is little different from testing a patchcord or cable plant using the two industry standard tests, OFSTP-14 for double-ended loss (connectors on both ends) or FOTP-171 for single-ended testing. In fiber optic networks, particularly in FTTx (Fiber to the x) and PON (Passive Optical Networks) deployments, splitters play a central role in distributing the optical signal from a single source to multiple destinations. There are no specific requirements for this document. This document is not restricted to specific software and hardware versions. One important note is that splitting architectures should be seen as tools that can be mixed and matched to. Optical splitter loss refers to the decrease in optical power that happens when a single optical signal is split among multiple output ports in a fiber optic network.
