1. Yog dab tsiFTTA?
-FTTA"FiberTo The Antenna” yog ib lub network wireless architecture tshiab uas siv cov fiber optic cables los txuas cov antennas ncaj qha mus rau cov chaw nres tsheb los ntawm BBU. Nws tab tom hloov cov coax tooj liab rau bandwidth siab dua, latency qis dua (tseem ceeb rau 4G / 5G). Siv cov fiber optic cable nrog qhov hnyav tsawg dua, kev siv hluav taws xob zoo dua (ambient cooling), thiab kev txhim kho qhov zoo ntawm lub teeb liab, nws tso cai rau cov cellular towers me dua, sib dua, thiab muaj peev xwm.
- FTTA cov kev daws teeb meem feem ntau sivCPRI daim kab xev(qhov kev xaus nrog DLC connector-sib xws nrog Huawei, Nokia, Ericsson cov khoom siv) los txuas BBU rau RRH, yog li ua kom qhov kev sib kis ceev dua thiab ua kom muaj thaj chaw dav dua, sai dua, thiab ruaj khov dua.
- Ntawm FTTA kev daws teeb meem, cov fiber ntau optical khiav mus rau lub pej thuam mus rau Lub Taub Hau Xov Tooj Cua Deb (RRH) ze ntawm Antenna, tswj cov teeb liab digital; lub zog xa mus los ntawm tus neeg coj sib cais lossis koom ua ke rau hauv cov xov hlau fiber.
2. Cov txiaj ntsig tseem ceeb ntawm FTTA kev daws teeb meem:
- Txog Bandwidth & Ceev: Txhawb nqa cov ntaub ntawv loj heev ntawm 4G / 5G.
- Txog Qhov Hnyav & Lub Hnyav Cua: Cov xov hluav taws xob sib dua txo qhov kev ntxhov siab ntawm lub pej thuam thiab kev tiv thaiv cua.
- Txog Kev Siv Hluav Taws Xob Zoo: RRHs ntawm qhov siab siv cua txias ntuj, txuag hluav taws xob.
- Txog Kev Ncaj Ncees ntawm Lub Teeb Liab: Tsawg dua qhov teeb liab puas tsuaj thiab suab nrov piv rau tooj liab.
- Txog Kev Teeb Tsa: Yooj yim dua, teeb tsa sai dua nrog cov cables me dua, sib dua.
- Txog Kev Ywj Pheej: Cov chav Baseband (BBUs) tuaj yeem ua ke, ua kom cov khoom siv saum toj kawg nkaus yooj yim dua.
3. Cov Qauv Network FTTA
Cov theem hauv qab no feem ntau yog koom nrog kev xa cov teeb liab los ntawm lub hauv paus band unit (BBU) mus rau lub Antenna (4G, 5G tower):
| Tshooj | Kev Ua Haujlwm | Cov khoom tseem ceeb |
| Chav Baseband Unit (chav Baseband) | Tswj RRU thiab ua cov teeb liab baseband | BBUFiber optic thaj vaj huam sib luag Sab nraum zoov Fiber Cable |
| RRU (Fiber kis tau tus mob) / BBU-RRU | Hloov cov teeb liab RRU baseband ntawm fiber | BS Chaw Taws Teeb Optic Cable Patch CordFTTA Connectors (PDLC, NSN, ODVA, FullAXS, Mini SC, OptiTap, thiab lwm yam) FTTA Lub Thawv Muaj Ntau Lub Luag Haujlwm |
| RRU (Chav Xov Tooj Cua Chaw Taws Teeb) | Hloov cov teeb liab optical rau cov teeb liab RF | RHRRRH Mounting Bracket |
| RRU - Antenna (RF Kis) | Lub kav hlau txais xov tau txais cov teeb liab RF | Feeder CableAntenna Feeder Jumper |
| Kav hlau txais xov | Cov teeb liab wireless: Kev xa thiab txais | AntennaSurge Protector |
Hauv 4G Base Station, fiber (FTTA) txuas BBU nrog RRU. RF pub cables txuas lub antenna.
Hauv 5G (AAU architecture), BBU, RRU, thiab antenna sib koom ua ke los ua DU. RRU thiab antenna tau koom ua ke rau hauv AAU siv kev sib txuas tag nrho-fiber kom txo qis RF poob thiab txhawb kev ua haujlwm.
