FTTH Optical Receiver(CT-2002C)
Overview
Ichi chigadzirwa iFTTH optical receiver, ichishandisa yakaderera-simba optical kugamuchira uye optical control AGC tekinoroji, iyo inogona kusangana nezvinodiwa zvefiber-to-the-imba, uye inogona kushandiswa pamwe chete neONU kana EOC kuwana kutamba katatu. Pane WDM, 1550nm CATV chiratidzo chephotoelectric kutendeuka uye RF yakabuda, 1490/1310 nm PON chiratidzo inopfuura nepakati, iyo inogona kusangana neFTTH imwe optical fiber transmission CATV + XPON.
Chigadzirwa chacho chakabatana muchimiro uye chiri nyore kuisa, uye 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 (1490/1310/1550nm) katatu kutamba application.
> SC/APC kana FC/APC optical connector, metric kana inch RF interface sarudzo.
> Iyo magetsi emagetsi maitiro eiyo 12V DC yekupinza port.

FAQ
FTTH Optical Receiver Mibvunzo Inowanzo bvunzwa
Q1. Chii chinonzi FTTH Optical receiver?
A: An FTTH optical receiver mudziyo unoshandiswa mufiber-to-the-home (FTTH) network. Yakagadzirirwa kugashira optical masaini kubva kune fiber optic network uye inoashandura kuita masaini emagetsi kuti awedzere kugadzirisa.
Q2. FTTH optical receiver inoshanda sei?
A: Iyo FTTH yekuona inogamuchira inotora yakaderera-simba optical reception uye otomatiki kuwana control (AGC) tekinoroji. Iyo AGC tekinoroji inova nechokwadi chekuti iyo yakagamuchirwa yemagetsi simba inoramba iri mukati meiyo yakatarwa nekugadzirisa kuwana kweanogamuchira. Izvi zvinova nechokwadi chekugamuchira chiratidzo chakavimbika uye kuita kwakanyanya.
Q3. Ndeapi mabhenefiti ekushandisa FTTH Optical receiver?
A: Kushandisa FTTH optical receivers kunounza akati wandei mabhenefiti kuFTTH network. Iyo inogonesa inoshanda fiber optic chiratidzo kugamuchira uye kutendeuka, ichigonesa yakakwirira-kumhanya Internet, yepamusoro-mhando yedhijitari TV, uye yakajeka izwi masevhisi. Pamusoro pezvo, inogona kusanganiswa neOptical Network Unit (ONU) kana Ethernet pamusoro peCoax (EOC) yemasevhisi ekutamba katatu.
Q4. Ndeapi mashandisirwo eFTTH Optical receivers?
A: FTTH optical receivers inonyanya kushandiswa muFTTH network kubatanidza nzvimbo dzekugara kana dzekutengesa nefiber optic infrastructure. Inoita senge mudziyo wekupedzisira unotora masaini ekuona anofamba netambo dzefiber optic uye oashandura kune masaini emagetsi akakodzera masevhisi akasiyana siyana, kusanganisira Internet, terevhizheni, uye izwi.
Q5. Iyo FTTH Optical receiver inogona kushandiswa nemimwe michina here?
A: Ehe, FTTH inogamuchira yekuona inogona kushandiswa pamwe neONU kana EOC kuona katatu play service. Iyo ONU inoshanda senge yepakati hub yekugovera Internet, TV uye masaini ezwi mukati menzvimbo, nepo FTTH inoona inogamuchira inovimbisa kugamuchira kwakavimbika uye kuchinjika kwezviratidzo izvi. Pamwe chete, ivo vanotsigira seamless yekubatanidza uye multimedia masevhisi muFTTH network.
