Wakambozvinyunyutira here kuti, "Iyi network yakaipa," kana internet yako ichinonoka? Nhasi, tichataura nezvePassive Optical Network (PON). Haisi network "yakaipa" yaunofunga nezvayo, asi mhuri yemagamba enyika yenetwork: PON.
1. PON, "Gamba Guru" reNyika yeNetwork
PONzvinoreva network ye fiber optic inoshandisa point-to-multipoint topology uye optical splitters kutumira data kubva panzvimbo imwe chete yekutumira kuenda kuma user endpoints akawanda. Ine optical line terminal (OLT), optical network unit (ONU), uye optical distribution network (ODN). PON inoshandisa entirely passive optical access network uye iP2MP (Point to Multiple Point) optical access system. Inopa zvakanakira zvakaita sekuchengetedza fiber resources, isingade simba reODN, kufambisa mushandisi kupinda, uye kutsigira multi-service access. I tekinoroji ye broadband fiber optic access iri kukurudzirwa nevashandisi.
PON yakafanana ne "Ant-Man" yenyika yekubatana: diki asi ine simba guru. Inoshandisa fiber ye optical senzira yekutumira uye inogovera masaini e optical kubva kuhofisi yepakati kuenda kuma endpoints akawanda evashandisi kuburikidza nemidziyo isingashande, zvichiita kuti masevhisi ekuwana broadband ashande nekukurumidza, anoshanda zvakanaka, uye asingadhuri.
Fungidzira dai nyika ye network yaive negamba guru, PON angadai ari Superman asinganyanyi kutaurwa. Hazvidi simba uye zvinogona "kubhururuka" munyika ye online, zvichiunza ruzivo rweInternet runokurumidza kuzviuru zvemhuri.
2. Mabhenefiti Akakosha ePON
Imwe ye "masimba makuru" ePON itransmission yayo inomhanyisa mwenje. Kana ichienzaniswa nenetwork dzekare dzewaya dzemhangura, PON inoshandisa optical fiber, zvichikonzera kumhanya kukuru kwetransmission.
Fungidzira uchidhawunirodha bhaisikopo kumba, uye rinoonekwa ipapo ipapo pamudziyo wako semashiripiti. Uyezve, fiber ye optical inodzivirira kurohwa nemheni uye kupindira kwemagetsi, uye kugadzikana kwayo hakuna kuenzana.
3. GPON & EPON
Nhengo mbiri dzinozivikanwa zvikuru dzemhuri yePON tekinoroji ndiGPON naEPON.
GPON: Simba reMhuri yePON
GPON, zvichireva Gigabit-Capable Passive Optical Network, ndiyo simba guru remhuri yePON. Nekumhanya kwedownlink kusvika ku2.5 Gbps uye kumhanya kweuplink kwe1.25 Gbps, inopa masevhisi edata, izwi, uye mavhidhiyo anomhanya kwazvo kudzimba nemabhizinesi. Fungidzira uchidhawunirodha bhaisikopo kumba. GPON inokutendera kuti utore mavhidhiyo ipapo ipapo. Uyezve, hunhu hweGPON husina kuenzana hunogona kuchinjika zvakanyanya kumusika webasa redata rebroadband.
EPON: Nyeredzi Inomhanya yeMhuri yePON
EPON, muchidimbu Ethernet Passive Optical Network, ndiyo nyeredzi yekumhanya yemhuri yePON. Nekumhanya kwakaenzana kwe1.25 Gbps kumusoro nekudzika, inotsigira zvakakwana vashandisi vane zvinodiwa zvakakura zvekuisa data. Kuenzana kweEPON kunoita kuti ive sarudzo yakakodzera kumabhizinesi nevagadziri vezvinyorwa vane zvinodiwa zvakakura zvekuisa.
GPON neEPON matekinoroji ese ari maviri ePON, akasiyana zvakanyanya muhunyanzvi, mwero wekutumira, maumbirwo efuremu, uye nzira dzekuvharira. GPON neEPON imwe neimwe ine zvayakanakira zvayo, uye sarudzo inoenderana nezvinodiwa zvekushandisa, bhajeti yemari, uye kuronga network.
Nekufambira mberi kwetekinoroji, musiyano uripo pakati pezviviri izvi uri kuramba uchiderera. Matekinoroji matsva, akadai seXG-PON (10-Gigabit-Capable Passive Optical Network) uyeXGS-PON(10-Gigabit-Capable Symmetric Passive Optical Network), inopa kumhanya kwakanyanya uye kushanda kuri nani.
Mashandisirwo ePON Technology
Tekinoroji yePON ine mashandisirwo akasiyana-siyana:
Kupinda pa internet pa internet kumba: Inopa mabasa einternet anomhanya zvakanyanya kune vashandisi vekumba, ichitsigira kuratidzwa kwevhidhiyo ine hunyanzvi hwepamusoro, mitambo yepamhepo, nezvimwewo.
Manetwork emakambani: Anopa mabhizinesi network dzakagadzikana, achitsigira masevhisi ekutumira data rakakura uye cloud computing.
PON inyanzvi "yemushandi akangwara." Nekuti haishande, mari yekugadzirisa inoderedzwa zvakanyanya. Vashandi havachadi kuisa nekuchengetedza michina yemagetsi yemushandisi wega wega, zvichichengetedza mari yakawanda. Uyezve, kugadziridzwa kwePON network kuri nyore kwazvo. Hapana kucherwa kunodiwa; kungovandudza michina panzvimbo yepakati kuchaita kuti network yese igadziriswe.
Maguta Akangwara: Mukuvaka maguta akangwara, tekinoroji yePON inogona kubatanidza masensa akasiyana-siyana nemidziyo yekutarisa, zvichigonesa kutakurwa kwakangwara, mwenje wakangwara, uye mamwe matekinoroji.
