Introduction
Singlemode non-dispersion shifted optical fibres with step-index according to CENELEC EN 60793-2-50 [5] with
cladding diameter of 125 μm (referred to as SM in the present document) are mostly deployed in telecommunication
networks. The rise of available transmission bandwidth per fiber is even significantly faster than e.g. the increase of
storage capacity of electronic memory chips, or the increase of computation power of microprocessors. The main
advantages of SM are:
• SM is the current communication wireline with the biggest bandwidth (up to 160 Gbit/s).
• SM is the current optical waveguide with the lowest optical losses (< 0,25 dB/km at 1 550 nm, see figure 1).
• SM is the waveguide with the best possibilities for wavelength multiplexing.
• SM optical connections have the best developed theory for optical interface with narrow uncertainties.
• There are reasonable compatibilities for connecting SM fibres of different types (considering losses).
• Complete immunity to ElectroMagnetic Interference (EMI).
• Compared with electrical cables, fiber-optic cables are very lightweight.
For all these reasons, SM is potentially the best and most sustainable solution for all telecommunication networks.

Figure 1: Singlemode fibre attenuation versus wavelength
The home network should not represent a bottleneck for the expected evolution for services such as the introduction of
High Definition quality IPTV, multi-room/multi-vision configuration, using different channels seen in different rooms
with up to 3 Set Top Boxes (STBs) and high quality video communication via the TV set. More in general, with the
"Connected Home", several devices are connected together: the home network can be used, for example, to share
multimedia contents not necessarily delivered in real time by access network, but with the paradigm of "download and
play" this content can be stored in a device inside the house and use it afterwards. However, this residential network
cabling as defined in CENELEC EN 50173-4 [47] should be easy, fast and cheap to deploy.
The home network should be able to manage multiformat and multiservice characteristics of the information delivered
by different service providers.
