6. SYSTEM THEORY
BRITECELL is an RF distribution/concentration system, based on electrical to optical conversion,
and fibre transmission.
It is mainly intended for cellular indoor coverage, because of its intrinsic high dynamic range, and
RF performances.
The DUAL BAND system provides coverage for two bands :one in the 800-1000 MHz range the
other in the 1700-2000 MHz1.
A local interface (composed of 6 plug in local interface modules or of 1 standalone local interface
unit) provides RF connection with BTS and conversion to optical in both UL and DL paths; each
Local interface has a single RF connector per path, while four optical connectors per path are
provided to interface the fibre cables driving the remote units.
The local interface modules can be combined in groups of two or three through one or more RF
combiners, according to the specific coverage and indoor cells design.
The local interface contains the required auxiliary circuitry, including AC mains power supply.
The remote transceivers provide air-interface to coverage area; each of them includes a high-
efficiency surface antenna, RF to optical interface in both UL and DL paths, RF LNA and PA,
control and auxiliary functions, and AC mains power supply.
An auxiliary RF port is available, to additionally connect a passive antenna for better coverage
shaping. The RF combiner is taken as part of the antenna feeder; the related loss is 3.8dB per
arm. The system can be provide with a customised feature (TFAad1H-c/2), which allows an
additional Pager transmit in Down link at 280 ± 5 MHz; it is suited to carry Flex or Pocsag signals.

7. TECHNICAL DETAILS
7.1 OPTICAL CONNECTORS
The system uses FC/APC optical connectors; DO NOT ATTEMPT TO INSERT OTHER
CONNECTORS, OTHERWISE SEVERE DAMAGE MAY OCCUR.
The FC/APC connector is a high precision optical alignment device; it must be handled with care,
to avoid scratches and other mechanical/optical damages that will impair or reduce the system’s
performance.
Do not touch the connector’s tip, and clean it with proper tissues before inserting them into the
sleeve. Do not leave connectors open. In case of better cleaning need, use only pure ethyl
alcohol.
Sleeves can be cleaned by injecting pure gas under pressure.
7.2 LOCAL INTERFACE
Refer to Table 1-2.
Two types of local interfaces are provided: a local interface composed of a 6 HE Subrack
(TPR912), 6 plug in local interface modules and one or more RF combiner, depending on the
system configuration or a standalone local interface.
The plug in interface modules must be handled with care and only by expert people paying
special attention to the optical fibre cables. In case you need to remove a local interface, you
should remove first the right adjacent module (whatever it is) or cover panel.
Local interfaces cannot be placed close to each other; one 7te module is always required.
IMPORTANT: prior to remove or insert any module make sure that power supply is off.
7.2.1 6HE SUBRACK TPR912
It can carry up to 6 Plug in local interfaces and the ancillary parts required by the system
configuration. The TPR912 includes the AC mains power supply, the required auxiliary circuitry
and alarms.
Alarm: a 9 pins sub D connector (male) on rear panel is used. See table 1 for functions and
pinout. All alarms are relay-contacts, where the relays are excited when NOT ALARMED.
If a local interface is not used, its related female connector on the backplane has to be closed by
a replacing male connector, which is provided together with the rack.
7.2.2 PLUG IN LOCAL INTERFACE MODULE
Refer to table 1.
The downlink laser transmitter is internally connected to an optical splitter, which provides four

Two LEDs give local status information (LD1 red, LD2 green) as follows:
LD2 lights when power supply is on.
LD1 lights as resume alarm in case of no optical power at downlink input and/or in case of failure.
The uplink laser is switched on only if downlink optical power is present. In case of any failure, the
laser is switched off.
