SYSTEM THEORYBRITECELL 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, andRF performances.The DUAL BAND system provides coverage for two bands :one in the 800-1000 MHz range theother in the 1700-2000 MHz1.A local interface (composed of 6 plug in local interface modules or of 1 standalone local interfaceunit) provides RF connection with BTS and conversion to optical in both UL and DL paths; eachLocal interface has a single RF connector per path, while four optical connectors per path areprovided 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 RFcombiners, 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 coverageshaping. The RF combiner is taken as part of the antenna feeder; the related loss is 3.8dB perarm. The system can be provide with a customised feature (TFAad1H-c/2), which allows anadditional Pager transmit in Down link at 280 ± 5 MHz; it is suited to carry Flex or Pocsag signals. 1 please refer to the specification sheets

TECHNICAL DETAILS7.1 OPTICAL CONNECTORSThe system uses FC/APC optical connectors; DO NOT ATTEMPT TO INSERT OTHERCONNECTORS, 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’sperformance.Do not touch the connector’s tip, and clean it with proper tissues before inserting them into thesleeve. Do not leave connectors open. In case of better cleaning need, use only pure ethylalcohol.Sleeves can be cleaned by injecting pure gas under pressure.7.2 LOCAL INTERFACERefer 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 thesystem configuration or a standalone local interface.The plug in interface modules must be handled with care and only by expert people payingspecial attention to the optical fibre cables. In case you need to remove a local interface, youshould 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 TPR912It can carry up to 6 Plug in local interfaces and the ancillary parts required by the systemconfiguration. The TPR912 includes the AC mains power supply, the required auxiliary circuitryand alarms.Alarm: a 9 pins sub D connector (male) on rear panel is used. See table 1 for functions andpinout. 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 bya replacing male connector, which is provided together with the rack.7.2.2 PLUG IN LOCAL INTERFACE MODULERefer to table 1.The downlink laser transmitter is internally connected to an optical splitter, which provides fouroutputs.The RF input port (SMA-female) must be connected to the BTS TX path, at the appropriate level(see specifications), eventually through the appropriate combiners configuration.
