1. Ni ikiFTTA?
-FTTA"FiberTo The A"ntenna" ni imiterere mishya igezweho y'umuyoboro wa wireless ikoresha insinga za fiber optique kugira ngo ihuze antene na sitasiyo z'ibanze ziturutse kuri BBU. Irimo gusimbura coax y'umuringa kugira ngo irusheho gukoresha umuyoboro wa interineti, igabanuke (ni ngombwa kuri 4G/5G). Koresha insinga ya fiber optique ifite uburemere buke, ikoresha ingufu nyinshi (gukonjesha mu kirere), kandi irusheho kunoza ubwiza bw'amajwi, bituma habaho iminara mito, yoroheje kandi ishoboye gukoresha telefoni.
- Ibisubizo bya FTTA bikunze gukoreshwaUmugozi w'agace ka CPRI(guhagarika hakoreshejwe DLC connector-ijyanye na Huawei, Nokia, Ericsson equipment) kugira ngo ihuze BBU na RRH, bityo yongere umuvuduko wo kohereza no gutuma ahantu hanini, hihuta kandi hahamye ho gukwirakwiza umuyoboro wa wireless.
- Kuri FTTA, fibre optique izamuka ku munara igera kuri Remote Radio Head (RRH) hafi ya Antena, ikora ibimenyetso bya digitale; ingufu zitangwa binyuze kuri conductor yihariye cyangwa zigashyirwa muri fibre.
2. Ibyiza by'ingenzi by'igisubizo cya FTTA:
- Ku bijyanye na Bandwidth & Speed: Ishyigikira ibyifuzo bikomeye bya 4G/5G ku makuru.
- Ku bijyanye n'uburemere n'umutwaro w'umuyaga: Insinga zoroheje zigabanya umunara n'ubudahangarwa bw'umuyaga.
- Ku bijyanye no gukoresha neza ingufu: RRHs iyo ziri hejuru zikoresha ubukonje bw'umwuka karemano, zigatanga ingufu zihagije.
- Ku bijyanye n'ubuziranenge bw'ibimenyetso: Kwangirika guke kw'ibimenyetso n'urusaku bingana ugereranije n'umuringa.
- Ibyerekeye gushyiraho: Gushyiraho byoroshye kandi byihuse hamwe n'insinga nto kandi zoroshye.
- Ku bijyanye no koroherana: Ibikoresho bya baseband (BBUs) bishobora gushyirwa hamwe, byoroshya ibikoresho byo hejuru y'iminara.
3. Imiterere y'umuyoboro wa FTTA
Intambwe zikurikira muri rusange zigize uruhare mu kohereza ikimenyetso kiva kuri bande y'ibanze (BBU) kijya kuri Antena (4G, 5G tower):
| Igice | Imikorere | Ibicuruzwa by'ingenzi |
| Icyumba cy'itsinda ry'abakina baseband (Itsinda ry'abakina baseband) | Igenzura RRU kandi igatunganya ibimenyetso bya baseband | BBUUrupapuro rw'urupapuro rwa Fiber optique Insinga yo hanze ya Fiber |
| RRU (Gukwirakwiza Fibre) / BBU-RRU | Kohereza ibimenyetso bya RRU baseband binyuze muri fibre | Umugozi wa BS Remote Optic Cable Patch CordAbahuza FTTA (PDLC, NSN, ODVA, FullAXS, Mini SC, OptiTap, nibindi) Agasanduku k'imikorere myinshi ka FTTA |
| RRU (Ishami rya Radiyo iri Kure) | Ihindura ikimenyetso cy'urumuri (optical signal) kikajya mu bimenyetso bya RF | Igikoresho cyo Gushyiraho RHRRH |
| RRU – Antena (Ubwikorezi bwa RF) | Antene yakira ibimenyetso bya RF | Inzira yo Kohereza Ibiryo Ifite Antena Ifite Ingufu zo Kohereza Ibiryo |
| Antena | Ibimenyetso bidafite umugozi: Kohereza no kwakira | Urinda AntenaSurge |
Muri sitasiyo ya 4G Base, fibre (FTTA) ihuza BBU na RRU. Insinga za RF feeder zihuza antene.
Muri 5G (architecture ya AAU), BBU, RRU, na antene bihurira hamwe bigakora DU. RRU na antene bihuzwa muri AAU hakoreshejwe uburyo bwa fibre bwose kugira ngo bigabanye igihombo cya RF no kongera imikorere.
4. Ni iki KCO Fiber ishobora gukora kuri wewe?
KCO Fiber izaba ari yo sosiyete igufasha kwizerwa mu gutanga ibicuruzwa bya FTTA fiber optic. Dushobora kuguha ibikoresho byose bijyanye na FTTA bifitanye isano na fiber optic nka:
- Insinga ya Fiber optique (Insinga ya fiber optique yo hanze, insinga ya ftth drop, insinga ya fiber optique ifite intwaro, insinga ya fiber optique yo mu murima, nibindi)
- Umugozi wo hanze wa fibre optique (umugozi wa CPRI, umugozi wo hanze ufite connector ijyanye na Fullaxs, NSN, Mini SC, OptiTap, PDLC, ODVA, nibindi)
- Agasanduku k'ibikoresho byinshi bya fiber optique ko hanze
- Umugozi wo hanze wa MPO ukoresha fibre nyinshi, nibindi
