Nowadays there are two known for the majority of the Internet users possibilities to build their home network – one based on Ethernet solution using the UTP (Unshielded Twisted Pair) cable; and the second one based on the WI FI technology.
Both used techniques have their disadvantages:
For the UTP they are:
- The cable length is limited to 100m
- The cable is thick and can not be hidden easy – always a big cable mess exist
- The quality of the connection can depend on the temperature, humidity, the electromagnetic radiation, etc.
- There are only fixed lengths of cables available of the market – for the home user is difficult to cut the cable and to mount the jack (special crimping tools are needed)
- If connectivity fails – it is difficult to find where exactly the problem is – you have to have always additional replacement cables
The WLAN connection have the following disadvantages:
- It creates electromagnetic radiation
- Sometimes, when the used devices are from different brands (the router and the WLAN card or USB adapter) is very difficult to build a stable connection
- Even coded and security protected, they are easy to hack – your neighbors can connect to the Internet through your WLAN modem and perform even criminal tasks, leaving you the responsibility.
I would like to propose another alternative for building of small home networks. It pretends to be the simplest to build, resistant to heat, humidity, vibrations, radio waves..etc.
This technique is based on the use of POF.
POF stands for plastic optical fiber .
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.
Due to its simplicity POF can carry Ethernet, USB, IEEE1394 and other protocols. The latest POF fibers operate at a wavelength of 650nm, are in mass production and offer state of the art network bandwidth. The fiber material is available in two main qualities; Low cost SI-POF with a core diameter of 1mm and a length of 50 to 100m. The 1mm core of GI-POF offers very high data rates combined with long range. The current GI bandwidth is in the range of > 3Gbps at 50m. The attenuation is < 200dB/km and the proposed bending radius is about 25mm. POF is very robust against vibration, EMI, zero radiation (EMC), humidity, provides high isolation, suited for explosive environments and has a wide temperature range. And it is easy to use. In other words the ideal networking media for you.
