Mu gihe cya 5G, umuyoboro wa interineti ukoresha insinga ukoresha uburyo bwa C-RAN bwo kubaka ahantu, kandi DU ikoreshwa mu buryo buri hagati.
Hari ahantu hamwe ha 5G hazaba hari ahantu hatandukanye n’ahasanzwe ha 4G. Hakenewe byihutirwa uburyo bwo gukwirakwiza imbere ya sitasiyo z’ibanze zifite ubwinshi bunini, kandi hari uburyo bwo gukwirakwiza imbere bwa fiber direct drive. Hari ibibazo byinshi nko gukoresha cyane umutungo wa fiber optique ndetse no kugorwa no kwaguka. Nk’ikigo gitanga serivisi zo gutanga ibisubizo by’itumanaho ry’amajwi, Shenzhen HUANET Technology Co., Ltd. yatangije uburyo bwo gukwirakwiza amakuru bwa WDM bwa 5G front haul passive kuri iyi ntego.
Ibiranga porogaramu
Ishyigikira CPRI 1 ~ 10 na eCPRI (10G / 25G), ijyanye na STM-1/4/16/64, GE / 10GE / 25GE n'izindi serivisi nyinshi zihuza, transmission isobanutse, yongera agaciro k'umuyoboro w'imodoka imbere.
Hatabayeho guhindura imiterere y'umuyoboro w'itumanaho, kwagura umuyoboro ufatika w'itumanaho riboneye, hatabayeho gutinda no guhungabana.
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
Ahantu ho gukorera hatabayeho gukora neza, hagabanya aho gutsindwa, hadakoreshwa uburyo bwo gukinisha no gukina, nta miterere, kandi hakoroshye kuyitunganya.
Multiplexer igabanya ubunini bw'uburebure ni nto kandi yoroheje, kandi ishyigikira uburyo bwinshi bwo kuyishyiraho nko gushyira ku rukuta, gushyira ku nkingi, gushyira ku nkingi, nibindi.
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 miyoboro ihari kandi imiyoboro mishya y'ifoto irashyirwa nta mbogamizi.
Iyo igihe cyo kubaka kigenwe, gishobora gukoreshwa nk'igisubizo cyihutirwa cyo gukemura by'agateganyo ikibazo cya fibre
