Mavuto Ofunika Kwambiri Okhudza Kutumizidwa kwa FTTH CATV PON
Musanayambe kufananiza zinthu, ndikofunikira kuthetsa zopinga zomwe mainjiniya am'munda amakumana nazo. Mavuto amenewa nthawi zambiri amasankha muyezo wa PON womwe ukugwirizana bwino ndi pulojekiti yanu.
Choyamba,kugwiritsanso ntchito zomangamanga zakaleMalo ambiri omwe alipo a FTTH adamangidwa mozungulira GPON. Eni ake a polojekitiyi akuyembekeza kusunga zingwe zoyambirira za ulusi, zopatulira ndi mabokosi ogawa kuti achepetse bajeti yomanganso. Komabe, si zida zonse zomwe zingathandize kukhala bwino kwa zizindikiro zakale ndi zatsopano. Kusagwirizanitsa bwino kungayambitse kutulutsa kwa kanema wa ONT kosakhazikika komanso kosakhazikika kwa CATV.

Sankhani GPON ngati:
Pulojekiti yanu ikufuna kufalitsa intaneti ya broadband kumidzi kapena kukonzanso pang'ono bajeti. Netiweki ya ODN yomwe ilipo kale ndi yokhazikika, kufunikira kwa bandwidth ya olembetsa kumakhala pansi pa 300Mbps pa banja lililonse, ndipo CATV overlay ndiye chofunikira chanu chachikulu. GPON yasonkhanitsa chidziwitso chachikulu chogwiritsidwa ntchito potumiza. Zida zosungira ndi zinthu zosamalira ndizosavuta kupeza m'misika yapadziko lonse lapansi.
Sankhani XGS‑PON ngati:
Mumagwira ntchito m'nyumba zokhala anthu ambiri, m'mahotela akuluakulu kapena m'malo okhala anthu osiyanasiyana. Ogwiritsa ntchito amafunika gigabit class symmetric bandwidth, ndipo mukuyembekezera kuti netiweki igwire ntchito zaka 6-8 zikubwerazi. Pankhaniyi,XGS‑PON imagwirizana ndi ONT yokhala ndi doko la CATVimabweretsa phindu lodziwikiratu kwa nthawi yayitali. Kumbukirani: GPON ndi XGS-PON zosakanikirana zomwe zikuyenda pa ulusi umodzi zimafuna ma module oyenerera a fyuluta mkati mwa OLT, musadumphe kasinthidwe aka kuti musunge ndalama kwakanthawi kochepa.
Pewani kugwiritsa ntchito molakwika
Musakakamize XGS-PON mixed mode deployment ngati gulu lanu pamalopo lilibe chidziwitso choyenera chothetsa mavuto a PON co-existence. Kusokoneza kwa wavelength yosiyana kungapangitse kuti zikhale zovuta kubwerezabwereza zolakwika zomwe zimadya anthu ambiri ogwira ntchito pambuyo pogulitsa.
Maphunziro Ochokera ku Machitidwe a Mapulojekiti a Dziko Lenileni
Kampani ina yolumikizira makina ku Southeast inakonza kale kukonzanso maukonde a malo opumulirako m'mphepete mwa nyanja. Poyamba, gululo linaganiza zoyika mwachindunji XGS-PON mixed-mode pa netiweki yoyambirira ya GPON fiber. Atayang'ana zoopsa zaukadaulo zomwe zalembedwa m'mafakitale, adayesa kaye mayeso ang'onoang'ono. Mayeso oyambirira adawonetsa kusinthasintha kwa zizindikiro popanda ma module oyenera a fyuluta. Pomaliza, adasankha zida za OLT zokhala ndi ma fyuluta ophatikizika ophatikizika, kusunga zigawo zambiri zoyambirira za ODN ndikuwonjezera ntchito ya XGS-PON ya nyumba zapamwamba za alendo, pomwe akusunga GPON kuti ikhale malo ogwiritsidwa ntchito nthawi zonse. Izi zidagawa bajeti, kukhazikika komanso mphamvu zowonjezera mtsogolo.
FAQ
Q: Kodi GPON ndi XGS‑PON zingagwire ntchito pa ulalo womwewo wa ulusi?A: Inde, koma zimatengera kapangidwe ka OLT hardware optical filter. Popanda ma wavelength isolation modules, kusokoneza kwa chizindikiro kudzachitika. Kuyesa kwa munda musanagwiritse ntchito mokwanira ndikofunikira kwambiri.
Q: Kodi XGS‑PON nthawi zonse ndi yabwino kwambiri pa ntchito za CATV overlay?A: Sizili choncho kwenikweni. Ngati olembetsa sakufuna bandwidth yofanana ya 10G, zida za GPON zokonzedwa bwino zitha kupereka ntchito yokhazikika ya CATV ndi broadband ndi ndalama zochepa zomwe zimagwiritsidwa ntchito pa projekiti.
Mapeto
Palibe muyezo wabwino kwambiri pakati pa GPON ndi XGS‑PON. Chisankho chanu chomaliza chiyenera kuyendetsedwa ndi mikhalidwe yomwe ilipo ya ODN, zofunikira pa bandwidth ya olembetsa, zosowa zautumiki wa CATV ndi bajeti ya polojekiti. Pa zochitika zophatikizana za FTTH‑CATV, kuthekera kwa hardware kudzipatula kwa ma signal ndi dynamic bandwidth schedule ndizofunikira mofanana ndi liwiro lotumizira.
Mukapeza zida za PON zama projekiti osiyanasiyana, onetsetsani kuti fyuluta ikugwira ntchito bwanji, momwe DBA imagwirira ntchito komanso momwe CATV imagwirizanirana ndi zida za 10G PON OLT ndi ma terminals ogwiritsa ntchito. Zida zodalirika zimakuthandizani kuchepetsa kuthamanga kwa debugging pamalopo komanso mavuto a nthawi yayitali mukamaliza kugulitsa.
