-## What is POF?

-

-POF stands for plastic optical fiber with the term plastic being used a vulgarization for polymer materials.

-

-The 1mm fiber diameter is about 500 times thicker than a glass optical fiber. 96% of the cores cross section conducts modulated light for data transmission similar to glass optical fiber applications. The maximal transmission distance amounts to about 100m without active repeaters. Polymer fibers are used for high speed data network in homes, commerce and industry as well as in cars and airplanes. POF is often regarded as an optical home network because POF is easy to install. The fiber is thin, can be shortened to the desired length by a sharp knife and requires no connectors on its ends. Anyone can set up a robust, high performance and Ethernet compatible network without any special tools.

-

-The key advantages of POF networks are:

-

-- No electromagnetic radiation

-- Electrically isolated network

-- Immunity against electromagnetic coupling

-- No electromagnetic cross talk

-- Flexible, reliable and maintenance-free

-- Low weight

-- Resistant to humidity, heat and vibration

-- Visible light that is eye-safe

-## POF distance

-

-| POF Type | Max Distance | Typical Data Rate | Notes |

-|------------------|--------------|-------------------|--------------------------------|

-| PMMA (Standard) | 50–100 m | 100 Mbps–1 Gbps | Common in home networks |

-| PF-POF | 200–500 m+ | 1 Gbps+ | Used in industrial/high-speed |

-## POF transmitter/receiver (Analog Fiber Opticc Transceiver)

-

-

-For the POF transmitter/receiver part was used the Firecomms Optolock FC300T.

-

-It includes the transmitting LED and the receiving PIN photodiode in one package.

-

-More information about the device can be found under the link: http://www.firecomms.com/ . The used Optolock is analog.

-

-Under desire a different type can be used (there are some which contain the receiver part embedded inside the same package), but the schematic and the PCB of the current implementation must be changed according the new requirements (in some cases differential to single ended conversion must be done).
