General Description.
The
REBLE610
is a very flexible microwave link that offers heterogeneous signals transport adapting
transmitting capacity to data stream.
It is the evolution of the already innovative and performing REBLE310, from which is distinguished by an
accurate hardware design, with particular care in the modularity and in avoiding any internal cabling.
The equipment is composed by a basic chassis and four swappable parts that make easy the maintenance
process and the always critical frequency change; a dual redundant power supply, hot swappable, is
present, available both in AC and DC version. A slot with the digital part (modem and data interface) has
been realized, as well as a module hosting the whole RF part (transmitter, receiver and channel filters).
The transmitters (at different frequencies) have been improved, being able to give always at least 1W at
output flange in any modulation scheme, introducing pre-correction and wideband calibration (up to 1 GHz,
depending on the frequency).
Data interface is equipped with 10 ASI/BTS ports on BNC connectors, configurable as input or output; this
feature let have in a single chassis the functions of an ASI matrix and an ASI distributor, both in input and
output. The link let also transfer IP traffic on a GbE port, an E1 2.048 Kbps signal and a “transit” connection
(just not to use too many coaxial cables for the transit).
With the optional XPIC module (and another REBLE610), it is possible to double the capacity of the link,
transmitting both in polarization H and V, erasing the undesired signal with special algorithms.
The compactness (1U rack 19”) is one of the main features, together with the care in the details for an easy
installation and maintenance, and the outstanding performances in terms of power, sensitivity and notch
tolerance.
The equipment can be half duplex (transmitter or receiver) or full-duplex.
