1. Chii chinonziFTTA?
-FTTA"FiberTo The A"tentenna" ihurongwa hutsva hwemazuva ano hwe "wireless network" hunoshandisa tambo dze fiber optic kubatanidza ma antenna zvakananga kunzvimbo dzebase kubva kuBBU. Iri kutsiva coax yemhangura kuti iwane bandwidth yakakwira, latency yakaderera (yakakosha pa4G/5G). Shandisa tambo ye fiber optic ine huremu hushoma, simba rinoshanda zviri nani (kutonhodza kwemhepo), uye kunaka kwemasaini, inobvumira nharembozha dzakatetepa, dzakareruka, uye dzinokwanisa kushanda.
- Mhinduro dzeFTTA dzinowanzo shandiswaTambo yechigamba cheCPRI(kugumisa neDLC connector-inoenderana neHuawei, Nokia, Ericsson equipment) kubatanidza BBU kuRRH, nokudaro zvichiwedzera kumhanya kwekutumira uye zvichiita kuti nzvimbo yakafara, inokurumidza, uye yakagadzikana yekuvhara network isina waya.
- Pamhinduro yeFTTA, fiber ye optical inomhanya ichikwira mushongwe ichienda kuRemote Radio Head (RRH) pedyo neAntenna, ichibata masaini edhijitari; simba rinounzwa kuburikidza neconductor yakasiyana kana kuti rinosanganiswa netambo yefiber.
2. Zvakanakira zvikuru zvemhinduro yeFTTA:
- Nezve Bandwidth & Speed: Inotsigira kudiwa kukuru kwedata re4G/5G.
- Nezve Huremu & Mutoro Wemhepo: Tambo dzefaibha dzakareruka dzinoderedza kushushikana kweshongwe uye kuramba mhepo.
- Nezve Kushanda Nesimba: MaRRH ari pakakwirira anoshandisa kutonhora kwemhepo yechisikigo, zvichichengetedza simba.
- Nezve Kuvimbika kweSignali: Kuderera kwekudzikira kwesignali uye ruzha zvichienzaniswa nemhangura.
- Nezvekuisa: Kuisa kuri nyore uye nekukurumidza netambo diki, dzakareruka.
- Nezvekuchinjika: Zvikamu zvebaseband (BBUs) zvinogona kuiswa panzvimbo imwe chete, zvichiita kuti michina ye tower top ive nyore.
3. Maumbirwo eNetwork yeFTTA
Matanho anotevera anowanzo shandiswa mukutumira chiratidzo kubva kubhendi rebase (BBU) kuenda kuAntenna (4G, 5G tower):
| Chikamu | Basa | Zvigadzirwa zvakakosha |
| Kamuri reBaseband Unit (Baseband Unit) | Inodzora RRU uye inogadzira masaini ebaseband | BBUPanera yefiber optic patch Tambo yeFiber yekunze |
| RRU (Fiber transmission) / BBU-RRU | Inotumira zviratidzo zveRSU baseband kuburikidza nefiber | Tambo yeBS Remote Optic Cable PatchFTTA Connectors (PDLC, NSN, ODVA, FullAXS, Mini SC, OptiTap, nezvimwewo) FTTA Bhokisi rine mabasa akawanda |
| RRU (Chikamu cheRemote Radio) | Inoshandura chiratidzo che optical kuita zviratidzo zveRF | Chikochekedzo Chekukwira cheRRHRH |
| RRU - Antena (RF Kutapurirana) | Antena inogamuchira zviratidzo zveRF | Cable yeAntenna Feeder Jumper |
| Kanyanga | Masaini asina waya: Kutumira nekugamuchira | Mudziviriri weAntennaSurge |
Mu4G Base Station, fiber (FTTA) inobatanidza BBU neRRU. Tambo dzeRF feed dzinobatanidza antenna.
Mu5G (AAU architecture), BBU, RRU, uye antenna zvinobatana kuti zvigadzire DU. RRU ne antenna zvinobatanidzwa muAAU uchishandisa kubatana kwe fiber yese kuitira kuderedza kurasikirwa kweRF uye kuwedzera mashandiro.
4. Chii chinogona kukuitira KCO Fiber?
KCO Fiber ichave mutengesi wako wezvigadzirwa zveFTTA fiber optic akavimbika. Tinogona kukupa zvese zvakagadzirwa zveFTTA zvine chekuita nefiber optic zvakaita se:
- Tambo yeFiber optic (Tambo yekunze yefiber optic, tambo yekudonhedza tsoka, tambo yefiber optic yakadzivirirwa, tambo yefiber optic yemunda, nezvimwewo)
- Tambo yekunze yefiber optic patch (Tambo yeCPRI patch, Tambo yekunze ine connector inoenderana neFullaxs, NSN, Mini SC, OptiTap, PDLC, ODVA, nezvimwewo)
- Bhokisi re fiber optic rine mabasa akawanda rekunze
- PLC splitter, MPO multi-fiber patch cord yekunze, nezvimwewo
