h1. 1. Introduction
This project is called "Evaluation and test of Earth stations are based on an optical / L-Band transceiver" indoor/outdoor unit architecture. The outdoor unit comprises antennas and has been developed by Gerald Haennig the RF frontend (amplifier and Ramon Gomez using up/down converter). The indoor unit includes the facilities of receiver, modem and network/application appliances. On typical consumer systems, the Telecom lab outdoor and indoor units are connected by means of Telecom Bretagne at ISAE-SUPAERO in Toulouse.
The aim of this project is to implement a ground optical system in order to convey the TV L-Band satellite signal to home. Since today, the most common procedure to do that is throughout 75-ohm coaxial cable. The cable directly from conveys the receiver antenna to intermediate frequency (typically L band) signal between the TV systems. However, this doesn't mean that the method indoor/outdoor units.
This approach, while being cost effective, is optimal, not optimal from a signal quality standpoint and actually is not, having a might severely impair the end-to-end link budget. For example, typical attenuation values for 1GHz a coaxial cable at a frequency of around 1 GHz are in the order of 15 dB/100m. In order to try to increase these performances, the proposal
The objective of this project is to substitute the coaxial by test and evaluate a monomode fiber link. This replacement will permit theoretically system that makes possible to set a link up convert the L-band RF signal from/to optical and use an optical fibre (up to 10km with much better performances than 10 km) as primary interconnection media. The signal is converted from optical back to RF in the coaxial.
indoor unit. As such, it is directed to DTH (Direct-To-Home) TV systems.
