Communal TV Systems are becoming more and more popular in MDUs (Multi-Dwelling Properties). The use of coaxial cabling is often the case in most MDUs, however, a more modern and efficient approach is the use of fibre optics. The problem with a lot of coaxial systems is that the signal can be affected by 'cable loss'. Cable loss increases as the signal travel down coaxial cables of a certain length. Therefore, modern fibre IRS systems mean there is effectively no limitation on the distance between the receiving antenna and the outlet location.
Another scenario where fibre IRS systems can be utilised is when there a lots of SDUs (single dwelling units), especially where satellite dishes and TV aerials are not permitted by planning agreements and design codes or where the reception from these antennas is inadequate for part of the site e.g. no line of sight to the satellite.
So its simple, right?
- A single antenna is placed in a suitable location
- The antenna is connected to an optical transmitter via coaxial cable.
- The transmitter is then connected to a network of splitters and switches called a PON (passive optical network).
- the optical feeds then get reconverted back to coaxial to feed each outlet in the desired properties.
