Is a home network necessary?
We receive many questions such as these.
When you really think about it now, it almost sounds like a dream, and doesn’t sound realistic.
However, today, the digital culture is spreading at astounding speeds. The Internet and cellular phones have begun and will continue to alter home electronic devices and the distribution methods of digital content.
And in the near future, when phone lines provide high speed connections to every household, there will definitely be a need to use these connections from any location in the house. That is where the home network comes in.

Types of Home Networks
Home networks can be divided into the following types.
Multimedia Network
This is an Audio-Visual communication system network. It requires a very wide bandwidth to provide features such as streaming video and pictures. This is a network which requires many functions, such as real time response and plug & play. It will become the driving force in changing the consumer market.
Example: IEEE1394
Control System Network
This is a network that provides low speed signals such as ON/OFF signals for lighting and security. It is a network made to make every-day life more convenient.
Example: EchoNet
PC System Network
This is a network using the current PC system, and is centralized around a PC. Can be used as a communication type network for SOHO and other uses.
Example: Ethernet
Other
Personal identification cards to replace keys, remote control, and others that provide an upper level user interface.
Example: Bluetooth

Why are plastic optical fibers drawing so much attention?
For when the need arises, a standard has been provided for a home network based on POF to provide an interface above 4.5m ? which is the present limit of a metal cable of IEEE1394.(IEEE1394b)
For example, in an average size Japanese of approx. 10m2, there is 6.3 meters of wall from one corner to the opposing corner. Between rooms, it can become necessary to use lines as long as 40 meters in length.
Having restrictions for where the TV can be placed because of the cable routing, or not being able to route the line in at all in some rooms is not satisfactory.
In an average home, routing the lines may prove to be very tedious, and may be hazardous in homes with young children.
It is possible to route quartz lines in homes but routing is difficult and cannot be conducted by just anyone; broken lines are very dangerous and could result in injury.
In a home, care must be taken for the young and the elderly - it's not uncommon for babies to chew on cables.
POF is made of large diameter plastic, so there is a much lesser chance that the cables will cause a stabbing wound, and anyone can work on it with simple tools - making it ideal for use in the home.
