Mazuvano, nekuenderera mberi kwekugadzirisa uye kukwidziridzwa kweoptical fiber modules, PON (passive optical fiber network) yave nzira yakakosha yekutakura Broadband kuwana network masevhisi. PON yakakamurwa kuita GPONuyeEPON. GPON inogona kunzi ishanduro yakakwidziridzwa yeEPON. Ichi chinyorwa, etu-link, chinounza iwe kuti unzwisise iyo GPON Optical module.
Chekutanga, tekinoroji yeGPON yakakwirira pane EPON maererano nekushandiswa kwebandwidth, mutengo, rutsigiro rwesevhisi yakawanda, OAM mabasa nezvimwe zvinhu. GPON inoshandisa scrabling code semutsara wekodhi, kungoshandura kodhi pasina kuwedzera kodhi, saka hapana kurasikirwa kwebandwidth. Panyaya yemutengo mumwe chete, mutengo wakaderera neGigabit's high-speed rate. Nekuda kweiyo yakasarudzika fomu yekurongedza, inogona kunyatso kutsigira ATM masevhisi uye IP masevhisi. OAM yakapfuma muruzivo, kusanganisira bandwidth mvumo yekugovera, dynamic bandwidth allocation (DBA), yekutarisa yekubatanidza, kuchengetedza switching, kiyi kuchinjanisa, uye akasiyana aramu mabasa.
Iyo GPON system optical module zvinodiwa zvakakamurwa kuita nhanho nhatu: A, B, uye C. Zviratidzo zvemaziso zvenhanho imwe neimwe zvakasiyana. Parizvino, inonyanya kukamurwa kuita makirasi b+ uye c+. Iyo yekugamuchira simba renji yeONUside rinowanzoita 1-2dBm yakaderera pane iyo yeOLTside. Misiyano yacho ndeiyi:
Basa guru reGPON ONU Optical module ndeyekugamuchira uye kuburitsa mwenje, iyo inowanikwa nelaser, shandura iyo modulated yemagetsi siginecha kuita chiratidzo chemaziso uye kuiisa mu optical fiber network yekutapurirana. Uyo anogamuchira anogamuchira chiedza, anowedzera chiedza chakagamuchirwa uye anochishandura kuva chiratidzo chemagetsi kune hurongwa hwekugadzirisa zviratidzo kuti uwane ruzivo runobatsira.Rudzi rwepakiti ndeye SFP, SC interface, chiyero chekutumira 1.25g / 2.5g, kureba kwekufambisa. inogona kusvika 20km. Iyo yekufambisa wavelength ndeye 1310nm uye iyo yekugamuchira yavelength i1490nm. DDM digital diagnostic function inotsigirwa, uye tembiricha yekushanda yegiredhi rekutengesa (0 °C - 70 °C) uye giredhi remaindasitiri (-40 °C - +85 °C) inosarudzwa.
Iye GPON OLT optical module yakaiswa neSFP, SC interface, 2.5g/1.25g transmission rate, 20km transmission distance, 1490nm transmission wavelength, 1310nm inogamuchira wavelength, uye kutsigirwa kweDDM digital diagnostic function, zvichiita kuti ive yakakodzera kune optical line terminals.
Iri pamusoro ndiyo tsananguro yeruzivo yeGPON optical module yakaunzwa neShenzhen HDV photoelectric Technology Co., Ltd. Zvigadzirwa zvemodule zvinogadzirwa nekavha yekambani. optical fiber modules, Ethernet modules, Optical fiber transceiver modules, Optical fiber access modules, SSFP Optical modules,uyeSFP optical fibers, etc. Zvigadzirwa zvemodule zviri pamusoro zvinogona kupa rutsigiro kune akasiyana network. Nyanzvi uye yakasimba R&D timu inogona kubatsira vatengi nenyaya dzehunyanzvi, uye timu inofunga uye ine hunyanzvi bhizinesi inogona kubatsira vatengi kuwana masevhisi emhando yepamusoro panguva yepamberi yekubvunzana uye mushure mekugadzira basa. Tinokugamuchirai taura nesu kune chero rudzi rwekubvunza.
