Mahwanda - mhinduro ano kuti bazi Network

The wired Indaneti kuti nokukurumidza uye kukwanisa Download risingaperi mashoko. Unobatanidza kuti network iri vachishandisa mumwe pafoni dzorunhare wire, uye kana imi havadi zvapedzisira, iwe ipapo nezvinetso hakuzomukizve. Zvisinei, kana tichida kuva yakatsiga Internet kubatana uye kubatana zvakajeka pafoni, zvakakodzera kushandisa mahwanda. Kombiyuta achasika zvakajeka uye akatsiga mureza vose pemitsara.

tsananguro

Mahwanda - chitsidzo wemagetsi, dzinobvisa digitaalinen anonongedzera frequencies zvakasiyana. Nechipiriso mudziyo unokubvumira dzaiitirwa matombo akawanda zvokushandisa mumwe coaxial mutsetse. Somuenzaniso, TV uye Modem.

Zvayakaita, ndiwo connector riri akashongedzerwa multiple zvengarava kubatanidza mano. Huru parameters kuti zvaizobatsira ine mahwanda - dzinoverengeka connectors kuti unobva mano. nhamba yavo zvichisiyana 2 kusvika 16 kana kupfuura. The zvakawanda zvengarava, mudziyo anonzi dzichipfekeka.

Kuwedzera mureza zvokushandisa, musika angawana akasimba shanduro splitters. zvigadzirwa izvi vanoparadzaniswa uye panguva imwe chete kutsigira mureza kupararira pamusoro madaro marefu, riri nyore pasina faibha-optic netambo.

Michina

ADSL (Asymmetric Digital rinotengeswa nevaridzi Line) - zvigadzirwa, izvo anoshanda ari mahwanda. Zvinokwanisika kuita kumhanya Data yedzimudzangara uye Kugamuchirwa ari rinotengeswa nevaridzi norunhare paruzhinji network. Yerera zvazvingava Kuparadzirwa ruzivo neeSultan:

• kubva 128 kbit / s uye 8Mbit / s pakugamuchira mushandisi mashoko;
• kubva 64 kbit / s 1 Mbit / s kuti kupararira mushandisi mashoko.

Panguva mashandiro, mudziyo zvemarudzi ose anonongedzera kuti foni uye Indaneti modems. Data Nzizi siyana kakawanda: runhare mutsetse maitire vose 0,3-3,4 kHz, nepo pomumbure anotumira mashoko ane kakawanda 0,26-1,4 MHz. Izvi hazvigoni zvachose kubvisa yakawiriranwa kwaiitika Namano pane mumwe kuti basa.

Uyezve, mahwanda mahwanda mberi revatema kudzivirira-siyana kuitika uye anogona kukuvadza chikwata. Kana kusashanda, nemambure anogona Musatya overvoltage kupomba kuitika panguva mabhanan'ana, dunhu pfupi, inoda kufunga kutapurirwa mutsetse dzenzvimbo.

Equipment nokuti TV

Pamwe achishandisa okuzvitsaura anonongedzera Indaneti uye foni anoshandisa splitters aiendeswa terevhizheni Network mudziyo. Ivo vanhuwo couplers dziri noruvara anoparadzirwa pakati dzakasiyana chiratidzo namano. The zvakawanda mapazi connector, simba, achapiwa kutepfenyurwa pamusoro chete "bhokisi" ose.

Kakawanda, ine mahwanda nokuti TV inoshandiswa kubatanidza akawanda mano chete kanyanga, Satellite receiver. Asi chivimbo ndewe zano chete yakavakwa-ari chiratidzo gudzazwi, kana zvikasadaro awane mufananidzo unhu haangavi zvinobvira.

mhando splitters

Its chaiyo zvinhu inopiwa nerimwe splitters. Ivo vanovimba mabikirwo iro akaberekwa mahwanda. Izvi zvinotungamirira maviri mhando inokosha:

• PLC-mano kushanda redhiyo mafungu kuwanda 1260 kusvika 1650 nm, izvo anobvumira kushandisa kwavo network dzakawanda ano.
• FBT-mano aigona zvakaenzana nokuparadzira mureza vakawanda zvinyorwa.

Kusarudza zvakarurama mudziyo pamumbure wako, unofanira kuisa pfungwa parameters maviri. Chokutanga izvi - ndiwo chiratidzo kakawanda inodiwa kuti nokushanda receiver. Zvakakodzera mahwanda aishanda chete siyana.

Chechipiri chinhu inoda kugadziriswa - ndiwo mwero attenuation ari chiratidzo inoratidzwa paterevhizheni yakatarwa uye dzimwe namano. Rezasi mutengo, akasimba nokupfuuridzirwa. Panyaya iyi, tinofanira zvichapfuura muna pakuvara mahwanda gudzazwi.

kubatanidza mitemo

Mune mugoveri unyorwe nemambure asina hombe. First batanidza mazano wire uye connectors kuti branching kunofambidzana waya kuti dzinotungamirira vagamuchiri siyana. Asi inonzi Nzira zvakajeka uye kugadzikana chiratidzo, zvakakodzera kuchengeta mitemo maviri:

1. Dzika kanyanga mahwanda pamberi vanoshingaira michina.
2. Regai interconnect maviri mahwanda.

Kana pashure unobva TV kuti mahwanda mufananidzo iri napakati, pakati waya uye connector vanofanira dzishandise mashoko ferrite mhete.
