O le oloa o loʻo i ai uiga o le fausaga faʻapipiʻi, faʻapipiʻi faigofie ma tau maualalo. O se oloa lelei mo le fausiaina o le cable TV FTTH network.
Fa'aaliga
> Atigi palasitika maualuga lelei ma lelei maualuga fua afi.
> Alaleo RF atoa GaAs le pisapisao fa'atele leo. Ole la'ititi o le mauaina o fa'ailoga numera o le -18dBm, ma le la'ititi o le mauaina o fa'ailoga analog e -15dBm.
> AGC pulega laina o -2~ -14dBm, ma o le galuega faatino e matua le suia. (AGC laina e mafai ona faʻapitoa e tusa ai ma le tagata faʻaoga).
> Fuafuaga faʻaogaina o le eletise maualalo, faʻaogaina le maualuga o le faʻaogaina o le eletise e faʻamautinoa ai le maualuga o le faʻatuatuaina ma le mautu maualuga o le eletise. O le faʻaaogaina o le eletise o le masini atoa e itiiti ifo i le 3W, faʻatasi ai ma le faʻaogaina o le moli.
> Fausia-i totonu o le WDM, iloa tasi fiber ulufale (1100-1620nm) talosaga.
> SC/APC ma SC/UPC po'o FC/APC feso'ota'iga mata, metric po'o inisi RF fa'aoga faitalia.
> Le fa'aogaina o le eletise o le 12V DC fa'aoga uafu.

FAQ
Q1. O le a le mea e maua ai le FTTH?
A: O le FTTH optical receiver o se masini e fa'aogaina i le fiber-to-the-home (FTTH) feso'ota'iga e maua ai fa'ailoga mata'utia e tu'uina atu e ala i uaea fa'apitoa ma fa'aliliuina i fa'amatalaga fa'aoga po'o fa'ailoga.
Q2. E fa'afefea ona galue le FTTH opitika tali?
A: O le FTTH opitika e talia fa'aogaina le maualalo o le mana fa'aogaina ma le fa'aogaina otometi otometi (AGC) tekinolosi. Na te talia fa'aoga fa'apipi'i ta'i tolu-ta'alo ma fa'atumauina le mautu o fa'ailo e ala i le AGC. E fa'aliliuina le faailoilo 1100-1620nm CATV i se eletise RF eletise mo polokalame uaea.
Q3. O a ni fa'amanuiaga o le fa'aogaina o le FTTH optical receiver?
A: Tulaga lelei o le faʻaogaina o le FTTH optical receivers e aofia ai le gafatia e lagolago ai fiber-to-the-home deployments, lea e mafai ona tuʻuina atu i luga ole Initaneti, TV ma telefoni feaveaʻi i luga ole fiber e tasi. E maua ai le maualalo o le eletise, faʻamautu faʻailoga faʻafeiloaʻi ma maualuga-lelei photoelectric liua mo faailoilo CATV.
Q4. E mafai e le FTTH opitika talileleia ona taulimaina umi galu eseese?
A: Ioe, FTTH optical receivers ma le WDM (Wavelength Division Multiplexing) gafatia e mafai ona taulimaina galu eseese, e masani lava i le va o le 1100-1620nm, e mafai ai ona latou taulimaina faʻailoga CATV eseese e tuʻuina atu i luga o laina fiber optic.
Q5. O le a le taua o le tekonolosi AGC i le FTTH optical receiver?
A: Automatic Gain Control (AGC) tekonolosi i le FTTH optical receivers e faʻamautinoa le mautu o faʻailoga e ala i le fetuunaʻi o le mana faʻaoga faʻapipiʻi e faʻamautu ai se tulaga faʻailo tutusa. Ole mea lea e mafai ai ona fa'atuatuaina, e le motusia le fa'asalalauina o fa'ailo CATV, fa'amautinoaina le fa'atinoga sili ona lelei mo fa'aoga fiber-to-the-home.
