Splitter - isisombululo mihla le network yesebe

Isantya Wired uqhagamshelwano lweIntanethi kunye nesakhono ukukhuphela data mda. Ixhuma kwinethiwekhi yi nge intambo ifoni, ukuba awufuni i yokugqibela, ngoko uneengxaki akayi kuvuka. Noko ke, xa uqhagamshelwano intanethi ezinzileyo kunye ikhonkco ecacileyo ifowuni kufuneka, kuyimfuneko ukusebenzisa iluthe. Esi sixhobo iza kudala umqondiso ocacileyo nozinzileyo zombini imida.

incazelo

Splitter - isixhobo compact elektroniki, lokucoca digital imiqondiso kunye ezitsho ezahlukeneyo. isixhobo thaca ikuvumela ukuba ukwazi ukuqhagamshela iintlobo ezininzi izixhobo enye kumgca yafakwa. Umzekelo, TV kunye modem.

Ngokwemo, nguwo isinxibelelanisi leyo lixhotyiswe kumazibuko ezininzi ukudibanisa nezixhobo. The main iparameters okuluphawu iluthe - inani izihlanganisi loqhakamshelwano izixhobo. Inani labo wahluka ukususela nge-2 ukuya ku-16 okanye ngaphezulu. Kumazibuko ngaphezulu, isixhobo uthathwa esebenza.

Ukongeza kwizixhobo eziqhelekileyo, imarike unako ukufumana uguqulelo eyomeleleyo gqiphu. Ezi mveliso zihlukaniswe kwaye ngaxeshanye ikhulise uphawu ukugqithisa phezu imigama emide, okufanelekileyo xa engekho fibre-optic.

ubuchwepheshe

ADSL (yezi Digital Umbhalisi Line) - ubuchwepheshe, leyo isebenza lo yokuchaka. Kuyenzeka ukufumana usulelo data ngesantya esiphezulu senxulumano kwaye yolwamkelo kwi zocingo rhumela kwi networks zoluntu. Flow izinga Ibanga distribution ulwazi:

• ukususela 128 kbit / s kunye 8Mbit / s ukufumana idata yomsebenzisi;
• 64 kbit / s 1 Mbit / s ukugqithisa ulwazi lomsebenzisi.

Ngexesha ukusebenza, ifowuni ukuhlela iziganeko ukuba imodem yefowuni kunye internet. imithombo yedatha ayahluka rhoqo: mnxeba nto luphawu lokuba bonke 0,3-3,4 kHz, kanti uthungelwano ithumela ulwazi nge frequency MHz 0,26-1,4. Oku ayikwazi ukubeka ecaleni ngokupheleleyo impembelelo efanayo yamacebo ngomsebenzi ngamnye zomnye.

Ukongeza, yokuchaka yokuchaka ngakumbi ukhuseleko kwiintlobo ezahlukeneyo ngoku kwaye zingonakalisa unit esidibeneyo. Xa yasebenza, inethiwekhi ayikwazi kuba ukubetha ukoyika overvoltage zisenzeka xa kukho isiphango, beesekethe elifutshane, elitsolo ekujongeni imisinga umgca transmission.

Izixhobo ye TV

Kunye ngemiqondiso ukwahlulwa-Intanethi yaye ifowuni isebenzisa gqiphu yenzelwe isixhobo womnatha umabonwakude. Bona couplers eqhelekileyo ukuba ngokufanayo isasazwe phakathi izixhobo ezahlukeneyo umqondiso. Amasebe ngaphezulu ukusuka isinxibelelanisi, ukuba buthathaka iya kusasazwa phezu kwezinto zonke "ibhokisi" single.

Amaxesha amaninzi, iluthe kuba TV lusetyenziswa ukuqhagamshela izixhobo ezininzi ukuya antenna eyodwa, receiver satellite. Kodwa ithemba ulingana isixhobo kunye msindo uphawu eyakhelwe-ngaphakathi, okanye enye esiyifumana iya kuba kunokwenzeka hayi umgangatho umfanekiso.

gqiphu imihlobo

iimpawu zayo ezizodwa zinikelwe nganye gqiphu. Baxhomekeke ubuchwepheshe apho yaveliswa yokuchaka. Oku kukhokelela iintlobo ezimbini:

• PLC-izixhobo ezisebenza ngamaza erediyo kuluhlu ukususela 1260 ukuya 1650 NM, nto leyo evumela ukusetyenziswa kwabo ezininzi networks mihla.
• FBT-ane of ngokulinganayo esasaza umqondiso kuzo imithombo emininzi.

Ukuze ukhethe icebo ekunene kumnatha wakho, kufuneka unikele ingqalelo parameters ezimbini. Eyokuqala kwezi - ke amaza uphawu olufunekayo ukusebenza yomfumani. Kuyimfuneko ukuba yokuchaka wasebenza obufanayo.

Into yesibini efuna ingqalelo - liqondo of eziphango yomqondiso iboniswe kwi umabonakude kunye nezinye izixhobo. Okuya kusiba phantsi kwexabiso, ngokuqina ugqithiso. Kulo mzekelo, imfuno izakulahleka kwi yokuchaka wokukhulisa eyakhelwe-ngaphakathi.

imithetho uqhagamshelo

Xa ehlukanisayo ukubandakanywa kwi network akukho nto ibitheni ngotywala. Okokuqala qhagamshela intambo igalelo nezidibanisi ukuya eyayizalwa kukuba ngcingo inxibelelene ezikhokelela balwamkele ezahlukeneyo. Kodwa ukuze kuqinisekiswe ubuchule icacile kwaye uphawu oluzinzileyo, kuyimfuneko ukuba uyigcine imithetho ezimbini:

1. Ukusebenzisa eriyali yokuchaka phambi izixhobo esebenzayo.
2. Musa uqhagamshelo le yokuchaka ezimbini.

Ukuba emva odibanisa TV kumfanekiso yokuchaka liyacandeka kubini, phakathi intambo kunye isinxibelelanisi kufuneka ufake i ring ferrite.
