Paunenge uchiongorora sarudzo dzehardware, usatarise chete pamatanho emutengo wepamusoro. Kune mapurojekiti akabatanidzwa eFTTH CATV, nyatsotarisa kugona kwe optical filter kwakavakirwa mukati uye mashandiro eDBA scheduling eMidziyo ye10G PON OLTMidziyo yakawanda inodhura pamusika inobvisa mukana wekushandisa mamodule maviri aya, izvo zvinoita kuti mavhidhiyo agare achivharirwa kana paine basa rakawanda renguva chaiyo.
Gwaro Rekuita Sarudzo: Ndeipi Mhinduro Yaunofanira Kusarudza?
Sarudza GPON kana:
Chirongwa chenyu chakanangana nekuburitswa kwebroadband kumaruwa kana kugadziriswa kwebhajeti shoma. Network yeODN iripo yatogadzikana, kudiwa kwebandwidth yevanyoreri kuri pasi pe300Mbps pamhuri, uye CATV overlay ndiyo chinhu chikuru chinodiwa. GPON yakaunganidza ruzivo rwakakura rwekuiswa kweinternet. Zvikamu zvekuchengetedza uye zviwanikwa zvekugadzirisa zviri nyore kuwana mumisika yepasi rose.
Sarudza XGS‑PON kana:
Unoshanda mudzimba dzine vanhu vakawanda, mumahotera makuru kana munzvimbo dzekugara dzakasanganiswa dzemabhizinesi. Vashandisi vekupedzisira vanoda bandwidth yemhando yegigabit, uye unotarisira kuti network ishande kwemakore matanhatu nemasere anotevera. Muchiitiko ichi,XGS‑PON inoenderana neONT ine CATV portzvinounza kukosha kuri pachena kwenguva refu. Yeuka: GPON yakasanganiswa neXGS-PON inomhanya pamusoro pefaibha imwe chete inoda mamodule efirita akakodzera mukati meOLT, usadarike gadziriro iyi kuti uchengetedze mari yenguva pfupi.
Dzivisa kushandiswa zvisina kunaka
Usamanikidza XGS-PON mixed mode deployment kana timu yako iri panzvimbo isina ruzivo rwakakodzera rwekugadzirisa PON co-existence. Kupindira kwewavelength isina kusarudzwa kuchaita kuti zvive zvakaoma kuburitsa zvikanganiso zvinogara zvichiitika izvo zvinodya vashandi vakawanda mushure mekutengesa.
Zvidzidzo Kubva Mumaitiro Ekuita Mapurojekiti Epasi Rechokwadi
Imwe kambani inobatanidza masisitimu ekuSoutheast yakamboronga kugadzirisa network yenzvimbo yekutandarira iri pamhenderekedzo yegungwa. Pakutanga, timu yakafunga nezvekushandisa XGS-PON mixed-mode zvakananga paGPON fiber network yekutanga. Mushure mekuongorora njodzi dzeinjiniya dzakanyorwa muindasitiri, vakatanga vaita bvunzo dzemunda diki. Miedzo yekutanga yakaratidza kuchinja kwezviratidzo pasina mamodules akakwana ekusefa. Pakupedzisira, vakasarudza OLT hardware ine mafirita e optical akabatanidzwa, vachichengetedza zvikamu zveODN zvepakutanga uye vachiwedzera sevhisi yeXGS-PON yezvivakwa zvevaenzi zvepamusoro, ukuwo vachichengetedza GPON yenzvimbo dzinoshandiswa zvakanyanya. Kugoverwa uku kwakapatsanura bhajeti, kugadzikana uye kugona kwekuwedzera mune ramangwana.
Mibvunzo Inowanzo bvunzwa
Mubvunzo: Ko GPON neXGS‑PON zvinogona kushanda pamusoro pe fiber link imwe chete here?A: Ehe, asi zvinoenderana nekugadzirwa kweOLT hardware optical filter. Pasina wavelength isolation modules, kupindirana kwesignali kuchaitika. Kuongororwa kwemunda usati watanga kushanda kunokurudzirwa zvikuru.
Mubvunzo: Ko XGS‑PON inogara iri nani here kumapurojekiti eCATV overlay?A: Hazvisizvo chaizvo. Kana vanyoreri vasingade bandwidth ye10G yakafanana, hardware yeGPON yakagadzirwa zvakanaka inogona kupa sevhisi yeCATV nebroadband yakagadzikana nekushandisa mari shoma papurojekiti.
Mhedziso
Hapana mwero "uri nani" pakati peGPON neXGS‑PON. Sarudzo yako yekupedzisira inofanira kutungamirirwa nemamiriro aripo eODN, zvinodiwa zve bandwidth yevanyoreri, zvinodiwa nebasa reCATV uye bhajeti yepurojekiti. Kune zviitiko zvakabatana zveFTTH‑CATV, kugona kwehardware yekubvisa masaini uye kuronga bandwidth inochinja-chinja kunokosha zvakaenzana nekumhanya kwekutumira.
Kana uchitsvaga PON hardware yemabasa akasiyana-siyana, tarisa mashandiro esefa, mashandiro eDBA uye kushanda kweCATV kwe10G PON OLT michina uye materminal evashandisi. Hardware yakavimbika inokubatsira kuderedza kumanikidzwa kwekugadzirisa matambudziko panzvimbo uye matambudziko enguva refu mushure mekutengesa.
