1. YintoniI-FTTA?
-I-FTTA“Fi-iberTo The A"I-ntenna" luyilo olutsha lwanamhlanje lwenethiwekhi engenazingcingo olusebenzisa iintambo ze-fiber optic ukuqhagamshela ii-antenna ngqo kwizikhululo zesiseko ezivela kwi-BBU. Ithatha indawo ye-copper coax ukuze kubekho i-bandwidth ephezulu, i-latency ephantsi (ebalulekileyo kwi-4G/5G). Sebenzisa intambo ye-fiber optic enobunzima obuncinci, ukusebenza kakuhle kwamandla (ukupholisa okungqongileyo), kunye nomgangatho ophuculweyo wesignali, ivumela iinqaba zeselula ezincinci, ezikhaphukhaphu, nezikwaziyo ukusebenza.
- Izisombululo ze-FTTA zihlala zisetyenziswaIntambo yepetshi ye-CPRI(ukupheliswa kwesixhumi se-DLC esihambelana nezixhobo zeHuawei, Nokia, Ericsson) ukuqhagamshela i-BBU kwi-RRH, ngaloo ndlela kwandisa isantya sokudlulisa kunye nokwenza indawo yokugubungela inethiwekhi engenazingcingo ebanzi, ekhawulezayo, nezinzileyo.
- Kwisisombululo se-FTTA, i-optical fiber iqhuba inyuka inqaba ukuya kwi-Remote Radio Head (RRH) kufutshane ne-Antenna, iphatha imiqondiso yedijithali; umbane uhanjiswa nge-conductor eyahlukileyo okanye udityaniswe kwintambo yefayibha.
2. Iingenelo eziphambili zesisombululo se-FTTA:
- Malunga neBandwidth kunye neSpeed: Ixhasa iimfuno ezinkulu zedatha ze-4G/5G.
- Malunga nobunzima kunye nomthwalo womoya: Iintambo zefayibha ezikhaphukhaphu zinciphisa uxinzelelo lwenqaba kunye nokumelana nomoya.
- Malunga nokusebenza kakuhle kwamandla: Ii-RRH xa ziphezulu zisebenzisa ukupholisa umoya wendalo, zigcina amandla.
- Malunga noBulungisa beSignali: Ukuwohloka kwesignali kunye nengxolo encinci xa kuthelekiswa nobhedu.
- Malunga noFakelo: Ufakelo olulula nolukhawulezayo ngeentambo ezincinci nezikhaphukhaphu.
- Malunga nokuguquguquka: Iiyunithi ze-baseband (ii-BBU) zingafakwa kwindawo enye, nto leyo eyenza kube lula izixhobo ze-tower top.
3. Ulwakhiwo lweNethiwekhi ye-FTTA
La manqanaba alandelayo ngokubanzi abandakanyeka ekudlulisweni kwesiginali ukusuka kwiyunithi yebhendi yesiseko (i-BBU) ukuya kwi-Antenna (4G, 5G tower):
| Icandelo | Umsebenzi | Iimveliso eziphambili |
| Igumbi leyunithi yeBaseband (iyunithi yeBaseband) | Ilawula i-RRU kwaye icwangcise imiqondiso ye-baseband | I-BBUIphaneli yepetshi ye-fiber optic Intambo yeFiber yangaphandle |
| I-RRU (Ukudluliselwa kweFayibha) / BBU-RRU | Ukudlulisela imiqondiso ye-RRU baseband ngefayibha | Intambo yePatch ye-BS Remote Optic CableIziqhagamshelo zeFTTA (PDLC, NSN, ODVA, FullAXS, Mini SC, OptiTap, njl.njl) Ibhokisi ye-FTTA enemisebenzi emininzi |
| I-RRU (Iyunithi yeRadio ekude) | Iguqula isignali ye-optical ibe yisignali ye-RF | Isibiyeli sokuFakela i-RRHRH |
| I-RRU – I-Antenna (Ukudluliselwa kwe-RF) | I-antenna ifumana imiqondiso ye-RF | Ikhebula le-Feeder I-Antenna Feeder Jumper |
| I-antenna | Imiqondiso engenazingcingo: Ukuthumela nokufumana | Umkhuseli we-AntennaSurge |
Kwisikhululo se-4G Base, i-fiber (FTTA) iqhagamshela i-BBU ne-RRU. Iintambo ze-RF feed zidibanisa i-antenna.
Kwi-5G (uyilo lwe-AAU), i-BBU, i-RRU, kunye ne-antenna ziyadibana zenze i-DU. I-RRU kunye ne-antenna zidityaniswe kwi-AAU kusetyenziswa uqhagamshelo lwe-fiber yonke ukuze kuncitshiswe ilahleko ze-RF kunye nokunyusa ukusebenza.
4. Yintoni enokuyenza kwi-KCO Fiber?
I-KCO Fiber iya kuba ngumthengisi wakho wemveliso ye-FTTA fiber optic othembekileyo. Singakubonelela ngoluhlu olupheleleyo lwemveliso ye-FTTA fiber optic enxulumene ne-FTTA efana nale:
- Intambo ye-Fiber optic (Intambo ye-fiber optic yangaphandle, intambo ye-ftth drop, intambo ye-fiber optic exhonyiweyo, intambo ye-fiber optic yasentsimini, njl.njl.)
- Intambo ye-fiber optic yangaphandle (intambo ye-CPRI patch, intambo ye-patch yangaphandle ene-connector ehambelana neFullaxs, NSN, Mini SC, OptiTap, PDLC, ODVA, njl.njl.)
- Ibhokisi ye-fiber optic enemisebenzi emininzi yangaphandle
- I-PLC splitter, i-MPO multi-fiber patch yangaphandle, njl.njl.
