FTTH Optical Receiver(CT-2001C)
Mwachidule
Izi ndi FTTH kuwala wolandila.Imatengera ukadaulo wocheperako wolandila komanso wowongolera wa AGC kuti ukwaniritse zosowa za fiber-to-the-home.Gwiritsani ntchito kulowetsa katatu kowonera, kuwongolera kukhazikika kwa siginecha kudzera pa AGC, ndi WDM, 1100-1620nm CATV chizindikiro cha photoelectric kutembenuka ndi pulogalamu ya RF yotulutsa chingwe TV.
Zogulitsazo zimakhala ndi mawonekedwe a compact, kukhazikitsa kosavuta komanso mtengo wotsika.Ndi mankhwala abwino kumanga chingwe TV FTTH maukonde.
Mbali
> Chipolopolo chapulasitiki chapamwamba kwambiri chokhala ndi moto wapamwamba kwambiri.
> RF channel full GaAs low phokoso amplifier circuit.Kulandila kocheperako kwa ma siginecha a digito ndi -18dBm, ndipo kulandila kochepa kwa ma analogi ndi -15dBm.
> AGC control range ndi -2~ -14dBm, ndipo zotuluka zake sizinasinthe.(Mtundu wa AGC ukhoza kusinthidwa malinga ndi wogwiritsa ntchito).
> Mapangidwe ogwiritsira ntchito mphamvu zochepa, pogwiritsa ntchito mphamvu zosinthika kwambiri kuti zitsimikizire kudalirika kwakukulu komanso kukhazikika kwamagetsi.Kugwiritsa ntchito mphamvu kwa makina onse ndi ochepera 3W, ndi dera lozindikira kuwala.
> WDM yomangidwa, zindikirani khomo lolowera ulusi umodzi (1100-1620nm).
> SC/APC ndi SC/UPC kapena FC/APC kuwala cholumikizira, metric kapena inchi RF mawonekedwe kusankha kusankha.
> Njira yoperekera mphamvu ya doko lolowera la 12V DC.

FAQ
Q1.Kodi FTTH Optical receiver ndi chiyani?
A: FTTH kuwala wolandila ndi chipangizo ntchito maukonde CHIKWANGWANI-kwa-kunyumba (FTTH) kulandira zizindikiro kuwala opatsirana kudzera zingwe kuwala ndi kusintha iwo mu deta ntchito kapena zizindikiro.
Q2.Kodi FTTH Optical receiver imagwira ntchito bwanji?
A: The FTTH kuwala wolandila utenga otsika mphamvu kuwala kulandirira ndi kuwala basi kupeza ulamuliro (AGC) luso.Imavomereza kulowetsedwa kosewera katatu ndikusunga kukhazikika kwazizindikiro kudzera pa AGC.Imatembenuza siginecha ya 1100-1620nm CATV kukhala chotulutsa chamagetsi cha RF pamapulogalamu a chingwe.
Q3.Ubwino wogwiritsa ntchito FTTH Optical receiver ndi chiyani?
A: Ubwino wogwiritsa ntchito FTTH optical receivers umaphatikizapo kuthandizira kutumizidwa kwa fiber-to-home, komwe kungapereke intaneti yothamanga kwambiri, ma TV ndi mafoni pamtundu umodzi.Amapereka mphamvu zochepa zogwiritsira ntchito mphamvu, kulandirira kokhazikika kwa ma siginecha komanso kutembenuka kwamphamvu kwazithunzi kwa ma sign a CATV.
Q4.Kodi FTTH Optical receiver imagwira mafunde osiyanasiyana?
A: Inde, FTTH Optical receivers ndi WDM (Wavelength Division Multiplexing) amatha kupirira mafunde osiyanasiyana, nthawi zambiri pakati pa 1100-1620nm, kuwapangitsa kuti azigwira zizindikiro zosiyanasiyana za CATV zomwe zimafalitsidwa pazingwe za fiber optic.
Q5.Kodi ukadaulo wa AGC mu FTTH Optical receiver ndi chiyani?
A: Ukadaulo wa Automatic Gain Control (AGC) mu zolandila za FTTH zimatsimikizira kukhazikika kwa siginecha mwa kusintha mphamvu yamagetsi yowunikira kuti ikhalebe ndi siginecha yofananira.Izi zimathandizira kufalitsa kodalirika, kosadodometsedwa kwa ma sigino a CATV, kuwonetsetsa kuti magwiridwe antchito a fiber-to-the-home akuyenda bwino.
