5G y’ubucuruzi, niyo itwara imizigo mbere. Kubera ko imiyoboro ya 5G yihutishijwe cyane, nk'imwe mu miyoboro y’ibanze y’inganda zose za 5G, icyifuzo cy’imiyoboro ya 5G fronthaul kirimo kwiyongera. Mu gihe cya 5G, umuyoboro wa radiyo ushingiye ahanini ku miterere ya C-RAN, DU ikoreshwa mu buryo buhuriweho, kandi AAU nyinshi zihuzwa binyuze mu muyoboro wa fronthaul. Ibisubizo bya fronthaul bifatwa na C-RAN ahanini ni optique fibre direct drive, passive WDM na active OTN solutions, bifite ibibazo nko gukoresha fibre nyinshi, nta kugenzura no guhenda cyane; Shenzhen HUANET Technology Co., Ltd. yiyemeje kubaka umuyoboro wa 5G fronthaul mwiza cyane, niyo ya mbere yatangije umuyoboro wa 5G fronthaul semi-active, utuma umuyoboro wizewe kandi unanoza imicungire n’imikorere n’ubuziranenge bw’umuyoboro wa fronthaul.

Ibiranga porogaramu
Ishyigikira CPRI 1 ~ 10 na eCPRI (10G / 25G), ikorana na STM-1/4/16/64, GE / 10GE / 25GE n'izindi serivisi nyinshi zihuza, transmission isobanutse, yongera agaciro k'umuyoboro wa fronthaul.
Imiterere ya modular, 1:6/12/18 nta bushake, ishobora kugera ku guhuza kw'inzego nyinshi, ikanagabanya fibre nini
Hashobora gutangwa module zitandukanye z'urumuri rw'amabara, zishyigikira imiraba ya CWDM 18, imiraba ya MWDM 12, kandi zigahura n'ibisabwa mu ngengo y'imari y'umurongo
Gushyigikira uburinzi bwa optique 1: 1, igihe cyo guhindura uburinzi kiri munsi ya 50ms, bikongera ubwizigirwa bw'umuyoboro
Ishyigikira imicungire y'umuyoboro wa interineti, ikongera kubaka domaine zikoresha insinga n'itumanaho, kandi igenzura byimazeyo module y'ikoranabuhanga n'imiterere y'umurongo.
Ibikoresho bya WDM bikora ku biro bikuru bifasha amahitamo y'amashanyarazi ya AC 220V na DC -48V, uburinzi bw'amashanyarazi ya 1+1, kandi amashanyarazi yangiritse ntabwo agira ingaruka ku ihererekanya ry'ubucuruzi.
WDM idafite aho iherereye ikoresha ikoranabuhanga rya kure ifite ubushobozi bwo kuyikoresha hanze ndetse n'ahantu ho kuyikoresha horoshye.
Imiterere y'ikoreshwa
Ahanini hahuzwa n'ibikenewe mu mikoranire ya CRAN kuva aho ujya aho ujya, intera iri hagati ya DU na AAU iri muri kilometero 10.
Mu turere aho umutungo wa fibre optique ari muto, nta muyoboro w'amazi uhari, kandi imiyoboro mishya y'amazi irashyirwa nta mbogamizi.
Hubaka umuyoboro mwiza wo gukwirakwiza ibicuruzwa kugira ngo ushyigikire ibyo ubucuruzi bwa 5G bukeneye kandi bwizewe cyane
