1. Kodi n'chiyaniFTTA?
-FTTA“FiberTo The A"tentenna" ndi kapangidwe katsopano ka ma network opanda zingwe amakono pogwiritsa ntchito zingwe za fiber optic kulumikiza ma antenna mwachindunji ku malo oyambira kuchokera ku BBU. Ikusintha coax yamkuwa kuti ipange bandwidth yokwera, latency yotsika (yofunikira pa 4G/5G). Gwiritsani ntchito chingwe cha fiber optic chokhala ndi kulemera kochepa, kugwiritsa ntchito mphamvu moyenera (kuzizira kozungulira), komanso mawonekedwe abwino a chizindikiro, zimathandiza kuti ma cellular towers azikhala opapatiza, opepuka, komanso okhoza kugwira ntchito.
- Mayankho a FTTA nthawi zambiri amagwiritsa ntchitoChingwe cha CPRI(kuthetsa ndi cholumikizira cha DLC chomwe chikugwirizana ndi zida za Huawei, Nokia, Ericsson) kuti mulumikize BBU ku RRH, potero kuwonjezera liwiro la kutumiza ndikupangitsa kuti malo olumikizira ma netiweki opanda zingwe akhale otakata, othamanga, komanso okhazikika.
- Pa yankho la FTTA, ulusi wowala umakwera pamwamba pa nsanja kupita ku Remote Radio Head (RRH) pafupi ndi Antenna, ukugwira zizindikiro za digito; mphamvu imaperekedwa kudzera mu kondakitala wosiyana kapena kuyikidwa mu chingwe cha ulusi.
2. Ubwino waukulu wa yankho la FTTA:
- Zokhudza Bandwidth & Speed: Imathandizira kufunikira kwakukulu kwa data ya 4G/5G.
- Zokhudza Kulemera ndi Kulemera kwa Mphepo: Zingwe zopepuka za ulusi zimachepetsa kupsinjika kwa nsanja ndi kukana mphepo.
- Zokhudza Kugwiritsa Ntchito Mphamvu Mwachangu: Ma RRH okhala ndi mpweya wabwino kwambiri amagwiritsa ntchito kuziziritsa kwachilengedwe, zomwe zimathandiza kusunga mphamvu.
- Zokhudza Kukhulupirika kwa Chizindikiro: Kuchepa kwa kuwonongeka kwa chizindikiro ndi phokoso poyerekeza ndi mkuwa.
- Zokhudza Kukhazikitsa: Kukhazikitsa kosavuta komanso mwachangu ndi zingwe zazing'ono komanso zopepuka.
- Zokhudza Kusinthasintha: Magawo a baseband (BBUs) amatha kuyikidwa pakati, zomwe zimapangitsa kuti zida za tower top zikhale zosavuta.
3. Kapangidwe ka Netiweki ya FTTA
Magawo otsatirawa nthawi zambiri amakhudzidwa ndi kutumiza chizindikiro kuchokera ku unit ya base band (BBU) kupita ku Antenna (4G, 5G tower):
| Gawo | Ntchito | Zinthu zofunika kwambiri |
| Chipinda cha Baseband Unit (Gawo la Baseband) | Imawongolera RRU ndikugwiritsa ntchito zizindikiro za baseband | BBUChigamba cha fiber optic Chingwe cha Ulusi Wakunja |
| RRU (Kutumiza kwa Fiber) / BBU-RRU | Kusamutsa zizindikiro za RRU baseband kudzera mu ulusi | Chingwe cha BS Remote Optic Patch ChingweZolumikizira za FTTA (PDLC, NSN, ODVA, FullAXS, Mini SC, OptiTap, etc.) Bokosi la FTTA la Ntchito Zambiri |
| RRU (Chigawo cha Remote Radio) | Amasintha chizindikiro cha kuwala kukhala chizindikiro cha RF | Bulaketi Yoyikira ya RRRH |
| RRU – Antena (RF Transmission) | Antena imalandira zizindikiro za RF | Chingwe Chodyetsa Antenna Chodyetsa Jumper |
| Antena | Zizindikiro zopanda zingwe: Kutumiza ndi kulandira | Mtetezi wa AntenaSurge |
Mu 4G Base Station, fiber (FTTA) imalumikiza BBU ndi RRU. Zingwe za RF feed zimalumikiza antenna.
Mu 5G (AAU architecture), BBU, RRU, ndi antenna zimaphatikizana kupanga DU. RRU ndi antenna zimaphatikizidwa mu AAU pogwiritsa ntchito kulumikizana kwa fiber yonse kuti zichepetse kutayika kwa RF ndikuwonjezera magwiridwe antchito.
4. Kodi KCO Fiber ingakuchitireni chiyani?
KCO Fiber idzakhala kampani yanu yodalirika yogulitsa zinthu za FTTA fiber optic. Tikhoza kukupatsirani zinthu zonse zokhudzana ndi FTTA fiber optic monga:
- Chingwe cha fiber optic (Chingwe chakunja cha fiber optic, chingwe chotsika cha ftth, chingwe chotetezedwa cha fiber optic, chingwe cha fiber optic chakumunda, ndi zina zotero)
- Chingwe chakunja cha fiber optic patch (chingwe cha CPRI patch, chingwe chakunja cha patch chokhala ndi cholumikizira chogwirizana ndi Fullaxs, NSN, Mini SC, OptiTap, PDLC, ODVA, ndi zina zotero)
- Bokosi la fiber optic la ntchito zambiri lakunja
- PLC splitter, MPO multi-fiber outdoor patch cable, ndi zina zotero
