2. SYSTEM OVERVIEW
The equipment is manufactured in standard IP54 19” rack shelves and is powered by the
local mains supply. No battery backup is fitted.
The remote site receives the master site RF data via a dedicated fibre link. The downlink fibre
signals are transmitted to the remote site using 1310nm wavelength laser and the uplink
wavelength from remote to master site is 1550nm, using wave division multiplexing to
differentiate between the wavelengths. This means that a single fibre cable can be used for
both uplink and downlink, saving the considerable cost of an extra fibre cable between master
and each remote site.
The 10Watt output power remote BDA drives an air interfaced antenna for the local mobile
coverage.
