FTTH Optical Receiver(CT-2001C)
Overview
Ichi chigadzirwa iFTTH optical receiver. Iyo inotora yakaderera-simba yekuona yekugamuchira uye yekutarisa yekudzora AGC tekinoroji kusangana nezvinodiwa zvefiber-kumba-kumba. Shandisa katatu play optical input, dzora kugadzikana kwechiratidzo kuburikidza neAGC, neWDM, 1100-1620nm CATV chiratidzo chepikicha yekushandura uye RF inobuda tambo yeTV chirongwa.
Chigadzirwa chine hunhu hwe compact chimiro, nyore kuisirwa uye mutengo wakaderera. Icho chigadzirwa chakanakira kuvaka tambo yeTV FTTH network.
Feature
> Yepamusoro-mhando yepurasitiki shell ine yakanaka yakakwira moto chiyero.
> RF chiteshi izere GaAs yakaderera ruzha amplifier wedunhu. Iko kugashira kudiki kwemasaini edhijitari ndeye -18dBm, uye kugashira kushoma kwemasaini eanalogi ndeye -15dBm.
> AGC control range ndeye -2~ -14dBm, uye zvakabuda hazvina kuchinjwa. (AGC renji inogona kugadzirwa zvinoenderana nemushandisi).
> Yakaderera simba rekushandisa dhizaini, uchishandisa yakakwirira-inoshanda switching magetsi kuti ive nechokwadi chekuvimbika kwepamusoro uye kugadzikana kwakanyanya kwemagetsi. Iko kushandiswa kwesimba kwemuchina wese kushoma pane 3W, ine mwenje wekuona wedunhu.
> Yakavakwa-muWDM, ziva imwe fiber yekupinda (1100-1620nm) application.
> SC/APC uye SC/UPC kana FC/APC optical connector, metric kana inch RF interface sarudzo.
> Iyo magetsi emagetsi maitiro eiyo 12V DC yekupinza port.

FAQ
Q1. Chii chinonzi FTTH Optical receiver?
A: FTTH optical receiver chishandiso chinoshandiswa mufiber-to-the-home network (FTTH) kuti igamuchire masaini anofambiswa kuburikidza netambo dzemaziso uye oashandura kuita data inogona kushandiswa kana masaini.
Q2. FTTH optical receiver inoshanda sei?
A: Iyo FTTH yekuona inogamuchira inotora yakaderera-simba optical reception uye otomatiki kuwana control (AGC) tekinoroji. Iyo inogashira katatu-play optical kupinza uye inochengetedza kugadzikana kwechiratidzo kuburikidza neAGC. Iyo inoshandura iyo 1100-1620nm CATV siginecha kune yemagetsi RF kubuda kwetambo hurongwa.
Q3. Ndezvipi zvakanakira kushandisa FTTH Optical receiver?
A: Zvakanakira kushandisa FTTH optical receivers zvinosanganisira kukwanisa kutsigira fiber-to-the-home deployments, iyo inogona kupa yakakwirira-yekukurumidza Internet, TV uye nhare mabasa pane imwe fiber. Inopa kuderera kwesimba rekushandisa, yakagadzikana yekugamuchira chiratidzo uye yakakwirira-inoshanda photoelectric shanduko yeCATV masaini.
Q4. Ko iyo FTTH Optical receiver inogona kubata akasiyana wavelengths?
A: Hongu, FTTH optical receivers neWDM (Wavelength Division Multiplexing) inokwanisa kubata zvakasiyana-siyana zvewavelengths, kazhinji pakati pe1100-1620nm, zvichiita kuti vabate zviratidzo zvakasiyana-siyana zveCATV zvinotumirwa pamusoro petambo dzefiber optic.
Q5. Chii chakakoshera tekinoroji yeAGC muFTTH Optical receiver?
A: Otomatiki Kudzora Kudzora (AGC) tekinoroji muFTTH optical inogamuchira inovimbisa kugadzikana kwechiratidzo nekugadzirisa simba rekupinza rekuona kuchengetedza chiyero chechiratidzo. Izvi zvinogonesa kutapurirana kwakavimbika, kusingakanganiswe kweCATV masiginecha, kuve nechokwadi chekushanda kwakakwana kwefiber-to-the-imba application.
