Passive Optical Networking PON Local Area Network
A passive optical LAN, called POL or POLAN, is short for Passive Optical Local Area Network. It utilizes optical splitters to distribute data from one single source to multiple user endpoints. Not having a long history as a passive optical network (PON), it is a better replacement for copper-based LANs in local area networks. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers.

What materials are used to make fiber optic sensors
It is well-known the propagation of light in optical fiber is confined in the core of the fiber based on the total internal reflection (TIR) principle and near-zero propagation loss within the cladding, which is very important for the optical communication but limits its sensing applications due to the non-interaction of light with surroundings. Therefore, it is essential to exploit novel fiber-optic structures to disturb the light propagation, thereby enabling the interaction of the light with surroundings and constructing fiber-opti.
