1. Gịnị bụFTTA?
-FTTA"FireTo The A“ntena” bụ usoro netwọk ikuku ọhụrụ nke oge a nke na-eji eriri fiber optic jikọọ antenna ozugbo na ọdụ ntọala sitere na BBU. Ọ na-anọchi coax ọla kọpa maka bandwidth dị elu, obere latency (dị oke mkpa maka 4G/5G). Jiri eriri fiber optic nwere obere ibu, arụmọrụ ike ka mma (mkpọda gburugburu), yana mma mma nke akara ngosi, ọ na-enye ohere maka ụlọ elu sel dị obere, dị mfe, na nke nwere ike.
- A na-ejikarị ngwọta FTTA eme iheEriri patch CPRI(nkwụsị ahụ na njikọ DLC-dakọtara na ngwaọrụ Huawei, Nokia, Ericsson) iji jikọọ BBU na RRH, si otú a na-eme ka ọsọ nnyefe dịkwuo elu ma na-eme ka mpaghara mkpuchi netwọk ikuku dịkwuo obosara, ngwa ngwa, na kwụsie ike.
- Na ngwọta FTTA, eriri anya na-agbago elu ụlọ elu ahụ ruo Remote Radio Head (RRH) dị nso na Antenna, na-ejikwa akara dijitalụ; a na-enye ike site na konductor dị iche ma ọ bụ tinye ya na eriri eriri.
2. Uru dị mkpa nke ngwọta FTTA:
- Banyere Bandwit na Ọsọ: Na-akwado oke mkpa data nke 4G/5G.
- Banyere Ibu na Ibu Ifufe: Waya eriri dị mfe na-ebelata nrụgide ụlọ elu na iguzogide ifufe.
- Banyere Ike Arụmọrụ: RRHs n'ogo na-eji ikuku oyi eke eme ihe, na-azọpụta ike.
- Banyere Nkwụsi Ike nke Mgbaàmà: Mbelata mmebi na mkpọtụ mgbaàmà ma e jiri ya tụnyere ọla kọpa.
- Banyere Nwụnye: Nwụnye dị mfe ma dị ngwa ngwa site na iji obere waya ndị dị mfe.
- Banyere Mgbanwe: Enwere ike itinye nkeji baseband (BBUs) n'etiti, na-eme ka ngwa elu ụlọ dị mfe.
3. Nhazi Netwọkụ FTTA
Usoro ndị a na-abụkarị n'izipu mgbaama site na otu base band (BBU) gaa na Antenna (4G, 5G tower):
| Ngalaba | ọrụ | Ngwaahịa dị mkpa |
| Ụlọ Mgbakọ Baseband (Ngalaba Mgbakọ Baseband) | Na-achịkwa RRU ma na-ahazi akara baseband | BBUEriri optic patch panel Eriri eriri dị n'èzí |
| RRU (Nfefe Fiber) / BBU-RRU | Na-ebufe akara baseband RRU site na eriri | BS Remote Optic USB Patch eririNjikọ FTTA (PDLC, NSN, ODVA, FullAXS, Obere SC, OptiTap, wdg) Igbe Ọrụ Dị Iche Iche nke FTTA |
| RRU (Ngalaba Redio dịpụrụ adịpụ) | Na-agbanwe akara ngosi anya ka ọ bụrụ akara RF | Ngwakọta RRHRRH |
| RRU – Antenna (Nzipu RF) | Antenna ahụ na-enweta akara RF | eriri ... |

N'ime ọdụ isi 4G, eriri (FTTA) na-ejikọ BBU na RRU. Eriri nri RF na-ejikọ eriri antenna ahụ.
Na 5G (AAU architecture), BBU, RRU, na antenna na-ejikọta ọnụ iji mepụta DU. A na-ejikọta RRU na antenna na AAU site na iji njikọ eriri niile iji belata mfu RF ma kwalite arụmọrụ.
4. Kedu ihe KCO Fiber nwere ike imere gị?
KCO Fiber ga-abụ onye na-eweta ngwaahịa FTTA fiber optic a pụrụ ịtụkwasị obi. Anyị nwere ike ịnye gị usoro ngwaahịa fiber optic zuru oke dịka:
- eriri eriri optic (eriri eriri optic dị n'èzí, eriri ftth drop, eriri eriri optic armored, eriri eriri optic ubi, wdg)
- Eriri eriri optic dị n'èzí (eriri patch CPRI, eriri patch dị n'èzí nwere njikọ dakọtara na Fullaxs, NSN, Mini SC, OptiTap, PDLC, ODVA, wdg)
- Igbe eriri optic dị iche iche maka ime ụlọ
- PLC splitter, MPO multi-fiber mpụta patch waya, wdg
