Aisea le Fiber Optic Repeater?
Kingtone Fiber Optic Repeater system ua mamanuina e foia ai faafitauli o le vaivai telefoni feaveai, lea e sili atu le taugofie nai lo le setiina o se Base Station fou (BTS).Fa'atonuga autu o le RF Repeaters system: Mo le so'otaga i lalo, o fa'ailo mai le BTS e fafaga i le Master Unit(MU), ona fa'aliliu lea e le MU le fa'ailoga RF i le fa'ailo laser ona fafaga lea i le fiber e fa'asalalau atu i le Unite Mamao (RU).Ona liliu lea e le RU le faailo leisa i le faailo RF, ma faʻaaoga le Power Amplifier e faʻateleina ai le malosi maualuga ile IBS poʻo le antenna.Mo le so'oga i luga, O se fa'agasologa fa'afeagai, fa'ailo mai le telefoni feavea'i e fafaga i le uafu MS a MU.E ala i le duplexer, o le faailo e faʻateleina e ala i le faʻamalo leo maualalo e faʻaleleia ai le malosi o le faailo.Ona fafagaina lea o faailo i le RF fiber optical module ona liua lea i le laser signals, ona tuʻuina atu lea o le laser signal i MU, o le laser signal mai le RU ua liua i le RF signal e le RF optical transceiver.Ona faʻateleina lea o faʻailoga RF i faʻailoga sili atu le malosi e fafaga i le BTS.
Vaega:
- Fiber Optic RF Repeater o se fofo faʻatuatuaina e faʻalautele ma faʻaleleia le vaega faʻasalalau o le TETRA 400MHz network.
- E aofia ai vaega autu e lua, Master ma le tele o iunite Slave.
- 33, 37, 40 poʻo le 43dBm tuʻufaʻatasiga mana faʻapipiʻi, faʻafetaui tulaga faʻatulagaina
- Fa'afaigofie ona fa'apipi'i ma fa'aleleia e fa'aitiitia ai le ta'avale ma tau fa'agaioiga
- O le fa'asalalauina o fa'ailoga i le fiber optic repeater e le fa'alavelaveina e a'afiaga mai fafo
- Tuuina atu auaunaga fa'asalalau vave RF i lau TETRA Base-Station
- Lapo'a Fa'atasi ma Fa'atinoga Maualuga i totonu o le pa e le susu talafeagai mo fa'apipi'i i fafo ma totonu
