ANNEX 5 OPTICAL OPTION OP-001-PS
A5.1
GENERAL
A5.1.1 Description
This annex contains operating instructions for the next option:
OP-001-PS : Selective Optical Power Meter +
Optical to RF Selective Converter.
The evolution of the telecommunications market, more and more demanding in
quality standards, speed, services and so on and also economical and
competitiveness factors has changed the trend in telecommunications
installations, and increasingly, fibre-optics is being imposed on traditional ADSL
twisted-pair copper lines.
For this reason and in anticipation of an increase of fibre-optics installations, this
option has been developed. It is applicable to the
HD RANGER +
analysers and
allows adapting it in order to work with fibre-optics networks.
This optical module expansion includes two separate functions: The selective
optical power meter and the selective optical to RF converter.
The selective meter option allows measurements on optical fibre networks, which
are necessary to certify an installation according to the parameters set by local
policies.
The optical to RF selective converter has a photosensor for each wavelength,
which obtains the RF signal carried by each one. With this module, user can
measure terrestrial or cable (up to 1 GHz) networks or optical LNB for satellite
antennas (up to 5.45 GHz), so that the installer does not need any additional
equipment to measure this type of installations.
This expansion module is available for HD
RANGER
+ unit (both for new
equipments or to upgrade equipments owned).
