FTTH Optical Receiver(CT-2002C)
Mwachidule
Izi ndi FTTH kuwala wolandila, ntchito otsika mphamvu kuwala kulandira ndi kuwala kulamulira AGC luso, amene angathe kukwaniritsa zosowa CHIKWANGWANI-kunyumba, ndipo angagwiritsidwe ntchito molumikizana ndi ONU kapena EOC kukwaniritsa sewero katatu. Pali WDM, 1550nm CATV chizindikiro photoelectric kutembenuka ndi RF linanena bungwe, 1490/1310 nm PON chizindikiro mwachindunji akudutsa, amene angakumane FTTH wina kuwala CHIKWANGWANI kufala CATV + XPON.ndi kutsatira XGSPON chilengedwe,
The mankhwala ndi yaying'ono mu dongosolo ndi zosavuta kukhazikitsa, ndipo ndi mankhwala abwino pomanga 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 la fiber imodzi (1490/1310/1550nm) kuseweredwa katatu.
> SC/APC kapena FC/APC kuwala cholumikizira, metric kapena inchi RF mawonekedwe kusankha.
> Njira yoperekera mphamvu ya doko lolowera la 12V DC.

FAQ
FTTH Optical Receiver Mafunso Ofunsidwa Kawirikawiri
Q1. Kodi FTTH Optical receiver ndi chiyani?
A: An FTTH kuwala wolandila ndi chipangizo ntchito CHIKWANGWANI-kwa-nyumba (FTTH) maukonde. Amapangidwa kuti azilandira ma siginecha owoneka kuchokera ku ma fiber optic network ndikuwasintha kukhala ma siginecha amagetsi kuti apitilize kukonza.
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. Ukadaulo wa AGC umatsimikizira kuti mphamvu yolandila yolandila imakhalabe munjira inayake posintha phindu la wolandila. Izi zimatsimikizira kulandila kodalirika komanso magwiridwe antchito abwino.
Q3. Ubwino wogwiritsa ntchito FTTH Optical receiver ndi chiyani?
A: Kugwiritsa FTTH kuwala zolandirira kumabweretsa angapo ubwino FTTH maukonde. Imathandizira kulandira ndi kutembenuka kwa ma siginolo a fiber optic, kupangitsa intaneti yothamanga kwambiri, ma TV apamwamba kwambiri a digito, ndi mau omveka bwino. Kuphatikiza apo, itha kuphatikizidwa ndi Optical Network Unit (ONU) kapena Ethernet over Coax (EOC) pamaseweredwe atatu.
Q4. Kodi ntchito za FTTH Optical receivers ndi ziti?
A: FTTH kuwala zolandirira zimagwiritsa ntchito maukonde FTTH kulumikiza zogona kapena malonda malo CHIKWANGWANI chamawonedwe zomangamanga. Imakhala ngati chipangizo chomaliza chomwe chimatenga ma siginecha owoneka omwe akuyenda kudzera pazingwe za fiber optic ndikuzisintha kukhala ma siginecha amagetsi oyenera ntchito zosiyanasiyana, kuphatikiza intaneti, wailesi yakanema, ndi mawu.
Q5. Kodi FTTH Optical receiver ingagwiritsidwe ntchito ndi zida zina?
A: Inde, FTTH kuwala wolandila angagwiritsidwe ntchito limodzi ndi ONU kapena EOC kuzindikira ntchito sewero katatu. ONU imagwira ntchito ngati chigawo chapakati chogawa ma intaneti, ma TV ndi mauthenga a mawu mkati mwa malo, pamene FTTH optical receivers amatsimikizira kulandira ndi kusintha kwa zizindikiro izi. Pamodzi, amathandizira kulumikizana kopanda msoko ndi mautumiki amtundu wa multimedia mumanetiweki a FTTH.
