FTTA Cables: Ib qho tseem ceeb hauv kev sib txuas lus wireless

FTTA cables yog cov khoom tseem ceeb hauv kev sib txuas lus wireless, ua kom tsis muaj kev sib txuas ntawm lub hauv paus chaw nres tsheb thiab kav hlau txais xov. Xaiv txoj cai FTTA fiber ntau cables thiab txhim kho lawv kom raug yog qhov tseem ceeb rau kev ua haujlwm zoo hauv network. Hauv tsab xov xwm no, peb yuav tshawb xyuas seb FTTA cables yog dab tsi, qhov zoo thiab qhov tsis zoo ntawm FTTA thev naus laus zis, thiab kev cia siab ntawm FTTA fiber ntau cables.

FTTA Cable yog dab tsi?

FTTA Cable, luv luv rau Fiber rau Antenna Cable, yog ib hom tshwj xeeb ntawm fiber ntau optic cable tsim rau sab nraum zoov kev sib txuas lus infrastructure. Nws lub hom phiaj tseem ceeb yog txuas cov xov tooj cua nyob deb (RRUs) lossis antennas rau cov khoom siv hauv chaw nres tsheb hauv kev sib txuas lus wireless.

FTTA thev naus laus zis feem ntau yog siv hauv kev sib txuas lus hauv xov tooj ntawm tes, xws li 4G thiab 5G tes hauj lwm, qhov twg qhov kev thov rau bandwidth thiab txo qis latency yog qhov tseem ceeb. Nyob rau hauv ib tug raug FTTA xa mus, cov kav hlau txais xov xa mus rau lub hauv paus chaw nres tsheb ntawm fiber optic cables es tsis txhob ntawm tooj liab nyob ntawm tej. Qhov no ua rau kev sib kis tau nrawm dua thiab ua kom muaj peev xwm ua tau zoo hauv lub network.

FTTA: Qhov Zoo thiab Qhov Tsis Zoo

Kev hloov pauv mus rau FTTA coj ntau yam txiaj ntsig rau cov neeg siv khoom, cov neeg ua haujlwm, thiab cov kws tshaj lij. Txawm li cas los xij, ib yam li kev nce qib thev naus laus zis, qee qhov nyuaj thiab cov teeb meem yuav tsum tau daws.

Fiber-to-the-Antenna (FTTA) Zoo

Ib qho txiaj ntsig zoo tshaj plaws ntawm FTTA thev naus laus zis yog nyob rau hauv cov yam ntxwv ntawm lub cev ntawm lub cable nws tus kheej. Cov kab me me thiab qhov hnyav dua ntawm fiber ntau optic cables pab kom lawv nyob hauv tib qhov chaw raws li ib qho coaxial cable. Muab hais tias cov xov tooj ntawm tes tau raug rau ntau yam ib puag ncig, qhov loj me thiab cov khoom tshwj xeeb ntawm optical cabling ua rau lawv tsis tshua muaj kev puas tsuaj los ntawm cua daj cua dub.

Coaxial cables, nrog rau lawv cov teeb liab poob, txwv qhov kev ncua deb ntawm lub kav hlau txais xov thiab lub hauv paus chaw nres tsheb mus txog kwv yees li 100 meters. Hauv qhov sib piv, optical cabling tuaj yeem npog qhov deb mus txog 20 mais thaum muaj teeb meem tsawg tsawg.

Fiber-to-the-Antenna (FTTA) Disadvantages

FTTA tuaj nrog qee qhov muaj peev xwm tsis zoo tshwm sim los ntawm kev sib tw ntawm fiber ntau optics. Fiber optic cables yog qhov muag heev thiab yuav tsum tau ua tib zoo tuav. Cov av thiab plua plav ua rau muaj kev pheej hmoo loj rau fiber ntau optics, thiab cov cables raug rau sab nraum zoov yog qhov tshwj xeeb tshaj yog ua rau puas tsuaj. Tsis zoo li cov qauv siv hluav taws xob, kev cai fiber ntau optics feem ntau tsis hloov pauv, thiab cov fiber ntau puas yuav tsum tau hloov ntau dua li kev kho yooj yim. Kev txiav tawm hauv teb tuaj yeem ua tau ntau dua, ua rau cov nqi siab dua cuam tshuam nrog lub Hoobkas-txiav cables.

Lub neej yav tom ntej ntawm Fiber-to-the-Antenna (FTTA)

Raws li kev txhim kho ntxiv xws li cov kav hlau txais xov muaj zog ua ke nrog RRH kom tshem tawm qhov xav tau ntawm txhua qhov coax, me me ntawm tes technology, thiab ntauwd kev tsim kho txuas ntxiv mus, nws muaj kev nyab xeeb los xav tias yav tom ntej ntawm fiber-to-the-antenna yuav tuav ob peb ntxiv. xav tsis thoob.

Qhov tshwm sim ntawm 5G wireless, nrog kev sib txuas ceev mus txog 100 npaug sai dua 4G, yuav xav tau ntau lub xov tooj me me / DAS thiab kev txhim kho hauv cov kav hlau txais xov ntauwd bandwidth. Fiber optics yuav txuas ntxiv muab cov hlab ntshav rau lub network puas tau hloov zuj zus vim tias tsuas yog fiber ntau tuaj yeem txhawb nqa rov qab ntawm cov chaw me me uas tsim los ntawm qhov kev loj hlob ntawm cov tsheb loj no.

Fiber-to-the-antenna (FTTA) tau ua ib qho kev nce qib uas tsis muaj nuj nqis nyob rau hauv broadband architecture, tso cai rau kev pab them nqi kho mob raws li qhov xav tau tsis txaus. Los ntawm kev ua raws li qhov zoo tshaj plaws kev teeb tsa thiab kev kuaj fiber ntau tsis tu ncua, peb tuaj yeem ua kom tau raws li cov kev xav tau loj hlob ntawm peb lub zej zog "cellular".
