1. KuyiniI-FTTA?
-I-FTTA"Fi-iberTo The A"I-ntenna" iyisakhiwo esisha senethiwekhi engenantambo yesimanje esebenzisa izintambo ze-fiber optic ukuxhuma ama-antenna ngqo eziteshini eziyisisekelo ezivela ku-BBU. Ithatha indawo ye-coax yethusi ukuze kube nomkhawulokudonsa ophezulu, ukubambezeleka okuphansi (okubalulekile ku-4G/5G). Sebenzisa ikhebula le-fiber optic elinesisindo esincane, ukusebenza kahle kwamandla okungcono (ukupholisa okuzungezile), kanye nekhwalithi yesignali ethuthukisiwe, ivumela imibhoshongo yeselula emincane, elula, futhi enekhono.
- Izixazululo ze-FTTA zivame ukusetshenziswaIntambo yesichibi se-CPRI(ukuphela kwesixhumi se-DLC esihambisana nemishini ye-Huawei, Nokia, Ericsson) ukuxhuma i-BBU ku-RRH, ngaleyo ndlela kwandiswe isivinini sokudlulisa futhi kuvumele indawo yokumbozwa kwenethiwekhi engenantambo ebanzi, esheshayo, futhi ezinzile.
- Kusixazululo se-FTTA, i-optical fiber igijima ikhuphukele phezulu embhoshongweni iye ku-Remote Radio Head (RRH) eduze kwe-Antenna, iphatha amasignali edijithali; amandla alethwa nge-conductor ehlukile noma ahlanganiswe nekhebula le-fiber.
2. Izinzuzo ezibalulekile zesisombululo se-FTTA:
- Mayelana ne-Bandwidth kanye nesivinini: Isekela izidingo ezinkulu zedatha ze-4G/5G.
- Mayelana Nesisindo Nomthwalo Womoya: Izintambo zefayibha ezilula zinciphisa ukucindezeleka kombhoshongo kanye nokumelana nomoya.
- Mayelana Nokusebenza Kahle Kwamandla: Ama-RRH asezingeni eliphezulu asebenzisa ukupholisa komoya wemvelo, okusindisa amandla.
- Mayelana Nobuqotho Besignali: Ukuwohloka kwesignali okuncane nomsindo omncane uma kuqhathaniswa nethusi.
- Mayelana nokufakwa: Ukufakwa okulula nokusheshayo ngamakhebula amancane, alula.
- Mayelana Nokuguquguquka: Amayunithi e-baseband (ama-BBU) angafakwa endaweni eyodwa, okwenza kube lula imishini ye-tower top.
3. Isakhiwo Senethiwekhi ye-FTTA
Izigaba ezilandelayo ngokuvamile zihilelekile ekudlulisweni kwesiginali kusuka kuyunithi yebhendi yesisekelo (i-BBU) kuya ku-Antenna (4G, 5G tower):
| Ingxenye | Umsebenzi | Imikhiqizo ebalulekile |
| Igumbi Leyunithi Yebhendi Yesisekelo (Iyunithi Yebhendi Yesisekelo) | Ilawula i-RRU futhi icubungula amasignali e-baseband | I-BBUIphaneli ye-fibre optic patch Ikhebula Le-Fiber Langaphandle |
| I-RRU (i-Fiber transmission) / BBU-RRU | Idlulisela amasignali e-RRU baseband nge-fiber | Intambo yePatch yekhebula le-BS Remote OpticIzixhumi ze-FTTA (PDLC, NSN, ODVA, FullAXS, Mini SC, OptiTap, njll) Ibhokisi Lemisebenzi Eminingi le-FTTA |
| I-RRU (Iyunithi Yomsakazo Okude) | Iguqula isignali yokukhanya ibe yisignali ye-RF | Ibhulakhethi Yokufaka ye-RRHRH |
| I-RRU – I-Antenna (Ukudluliselwa kwe-RF) | I-antenna ithola amasignali e-RF | Ikhebula Lokuphakelayo I-Antenna feeder Jumper |
| I-Antenna | Amasignali angenantambo: Ukudlulisa nokwamukela | Isivikelo Sokukhuphuka Kwe-Antenna |
Esiteshini Esiyisisekelo se-4G, i-fiber (FTTA) ixhuma i-BBU ne-RRU. Izintambo zokuphakelayo ze-RF zixhuma i-antenna.
Ku-5G (ukwakheka kwe-AAU), i-BBU, i-RRU, kanye ne-antenna kuyahlangana ukuze kwakheke i-DU. I-RRU kanye ne-antenna kuhlanganiswe ku-AAU kusetshenziswa uxhumano lwe-fiber yonke ukuze kuncishiswe ukulahlekelwa yi-RF futhi kuthuthukiswe ukusebenza.
4. Yini i-KCO Fiber engakwenzela yona?
I-KCO Fiber izoba ngumhlinzeki wakho womkhiqizo we-FTTA fiber optic othembekile. Singakunikeza uchungechunge oluphelele lomkhiqizo we-FTTA fiber optic ohlobene nawe njenge:
- Ikhebula le-fiber optic (Ikhebula le-fiber optic langaphandle, ikhebula le-ftth drop, ikhebula le-fiber optic elihlomile, ikhebula le-fiber optic lasensimini, njll.)
- Intambo yesichibi se-fiber optic yangaphandle (intambo yesichibi se-CPRI, intambo yesichibi yangaphandle enesixhumanisi esihambisana ne-Fullaxs, NSN, Mini SC, OptiTap, PDLC, ODVA, njll.)
- Ibhokisi le-fiber optic elinezici eziningi langaphandle
- I-PLC splitter, i-MPO multi-fiber patch yangaphandle, njll.
