Splitter - isixazululo yesimanje inethiwekhi igatsha

isivinini Isilinganiswa noxhumano lwe-Inthanethi kanye nekhono ukulanda ledatha. Ixhuma kunethiwekhi nge ikhebuli ifoni yasendlini, futhi uma awudingi yokugcina, bese unezinkinga ngeke luvuke. Nokho, lapho kudingeka esitebeleni internet connection futhi isixhumanisi ecacile ocingweni, kubalulekile ukusebenzisa idabula. Le divayisi kuzodala uphawu olucacile oqine kokubili imigqa.

incazelo

Splitter - idivayisi compact electronic, ukuhlunga digital amasignali nge amaza ezahlukene. kudivayisi Kwethulwa ikuvumela ukuba ukuxhuma izinhlobo eziningi imishini omunye umugqa coaxial. Ngokwesibonelo, i-TV ne-imodemu.

Ikhipha kuba isixhumi okuyinto ifakwe nezimbobo amaningi ukuxhuma amadivayisi. Amapharamitha main agcwele idabula - eziningana nezixhumi yokuxhuma kumadivayisi. Inombolo yabo kuhluka 2 kuya ku-16 noma ngaphezulu. Emachwebeni ngaphezulu, idivayisi kubhekwa sokusebenza.

Ngaphezu imishini esezingeni, emakethe ungathola inguqulo eqinileyo splitters. Le mikhiqizo ehlukana nokuthi niyotshela kanyekanye zandisa isignali yokudlulisela olude, okufaneleyo ngokungabi bikho izintambo fiber-optic.

ubuchwepheshe

ADSL (Asymmetric Digital Subscriber Line) - ubuchwepheshe, nesebenzela le idabula. Kungenzeka ukuba sifinyelele high speed idatha ukuwudlulisa reception ku ngocingo zokubhalisa e omphakathi. Flow rate Imininingwane ukusatshalaliswa amabanga:

• kusuka 128 kbit / s bese 8Mbit / s ukuthola idatha yomsebenzisi;
• kusuka 64 kbit / s 1 Mbit / s yokudlulisa ulwazi umsebenzisi.

Ngesikhathi kokuhlinzwa, idivayisi bahlunga amasignali yefoni internet modems. Idatha ukusakaza ziyehluka imvamisa: emgqeni zocingo sici kuwo wonke 0,3-3,4 kHz, kuyilapho inethiwekhi ithumela ulwazi nge imvamisa MHz 0,26-1,4. Lokhu ngeke aluqede ngokuphelele ithonya mutual amadivaysi emsebenzini nomunye.

Ngaphezu kwalokho, idabula idabula okwengeziwe ihlanganiswe isivikelo izinhlobo ezahlukene amanje nawesikhathi okungase kulimaze iyunithi. Lapho ocushiwe, inethiwekhi akakwazi esabe ishayela overvoltage ezenzeka ngesikhathi nokuduma, short circuit, kumba ukudluliswa umugqa imisinga.

Isisetshenziswa-TV

Kanye ngezimpawu ngokuhlukana we-Inthanethi kanye Ifoni isebenzisa splitters senzelwe kudivayisi sokusakaza sethelevishini. Ziyakwazi couplers abavamile ukuthi nombala basakaza phakathi kumadivayisi ezahlukene isignali. Amagatsha ngaphezulu kusukela isixhumi, ubuthakathaka izosakazwa zonke "ibhokisi" olulodwa.

Isikhathi esining impela, idabula for TV isetshenziswa ukuxhuma amadivayisi amaningi ine-antenna eyodwa, umamukeli satellite. Kodwa ukwethenjwa kuwufanele idivayisi esakhelwe isignali amplifier, noma okunye athole ikhwalithi yesithombe ngeke kwenzeke.

izinhlobonhlobo splitters

Timphawu ekhethekile zinikelwe ngamunye splitters. Bathembele ubuchwepheshe okuyiwona kwatholwa le idabula. Lokhu kuholela izinhlobo ezimbili eziyisisekelo:

• PLC-amadivayisi sisebenze amagagasi omsakazo uhla 1260 kuya 1650 NM, okuvumela ukusetshenziswa kwabo amanethiwekhi zamanje.
• FBT-amadivayisi uyakwazi ngokulinganayo usabalalisa isibonakaliso emithonjeni eminingi.

Ukuze ukhethe idivayisi esifanele wenethiwekhi yakho, udinga ukugxila amapharamitha amabili. Eyokuqala yalezi - iyona imvamisa isignali adingekayo ukusebenza kwe-umamukeli. Kuyadingeka ukuba idabula wasebenza ububanzi efanayo.

Into yesibili ukuthi idinga ukunakwa - kuyinto degree of attenuation isignali kuboniswa phezu ithelevishini kanye namanye amadivayisi. The ephansi ukubaluleka, namandla ukudluliswa. Kulokhu, isidingo uzonyamalala e esakhelwe idabula amplifier.

imithetho uxhumano

Esikhathini ukufakwa ehlukanisayo kuleli inethiwekhi akunandaba ngempela. Okokuqala uxhuma ikhebula le-input bese izixhumi kuya amagatsha kuyinto izintambo axhunyiwe eziholela abamukelayo ezahlukene. Kodwa ukuqinisekisa inqubo kucacile futhi isignali ezinzile, kubalulekile ukugcina izimiso ezimbili:

1. Ukuqalisa antenna idabula phambi imishini asebenzayo.
2. Musa kuchunywa le idabula ezimbili.

Uma ngemva kokuxhuma TV esithombeni idabula is kabili, phakathi ikhebuli isixhumi Kuzomele ufake iringi ferrite.
