Xhuma irutha kuqala.
Imodemu ye-optical ixhunywe ku-router kuqala bese ishintsha, ngoba i-router idinga ukwaba i-ip, futhi inkinobho ayikwazi, ngakho-ke kufanele ibekwe ngemuva komzila.Uma ukuqinisekiswa kwephasiwedi kudingekile, vele, qala ngokuxhuma embobeni ye-WAN yomzila, bese uxhuma ekushintsheni okuvela embobeni ye-LAN.
Lisebenza kanjani ikati elikhanyayo
Imodemu ye-baseband yakhiwe ngokuthumela, ukwamukela, ukulawula, isikhombimsebenzisi, iphaneli yokusebenza, ukunikezwa kwamandla nezinye izingxenye.Idivayisi yetheminali yedatha ihlinzeka ngedatha edlulisiwe ngesimo sesignali ye-serial kanambambili, iyiguqule ibe ileveli yokunengqondo yangaphakathi ngokusebenzisa isixhumi esibonakalayo, futhi iyithumele engxenyeni ethumelayo, iyenze ibe isignali yokucela umugqa ngesekhethi yokushintshashintsha, futhi ithumele kuya emgqeni.Iyunithi eyamukelayo ithola isignali emugqeni, iyibuyisele kusignali yedijithali ngemva kokuhlunga, ukushintshashintsha okuphambene, nokuguqulwa kweleveli, futhi iyithumele kudivayisi yetheminali yedijithali.Imodemu yokubona iyisisetshenziswa esifana nemodemu ye-baseband.Ihlukile kumodemu ye-baseband.Ixhunywe kulayini ozinikele we-fiber optical futhi iyisiginali yokubona.
Umehluko phakathi kwemodemu yokubona, shintsha nerutha
1. Imisebenzi ehlukene
Umsebenzi wemodemu yokubona ukuguqula isignali yolayini wocingo ibe isignali yolayini wenethiwekhi ukuze isetshenziswe ku-inthanethi yekhompyutha;
Umsebenzi werutha ukuxhuma amakhompuyutha amaningi ngekhebula lenethiwekhi ukuze uthole uxhumano lokudayela okubonakalayo, ukukhomba ngokuzenzakalelayo ukuthunyelwa kwamaphakethe wedatha nokwabiwa kwekheli, futhi unomsebenzi wokuvikela umlilo.Phakathi kwazo, amakhompyutha amaningi abelana nge-akhawunti ye-broadband, i-inthanethi izothintana.
Umsebenzi wokushintsha ukuxhuma amakhompyutha amaningi ngekhebula lenethiwekhi eyodwa ukuze ubone ukusebenza kwe-inthanethi ngesikhathi esisodwa, ngaphandle komsebenzi werutha.
2. Ukusetshenziswa okuhlukile
Lapho imodemu yokubona ifinyelela ku-fiber optical ekhaya, iswishi nerutha zisebenza ku-LAN, kodwa iswishi isebenza kungqimba lwesixhumanisi sedatha, futhi umzila usebenza kusendlalelo senethiwekhi.
3. Imisebenzi ehlukene
Kalula nje, imodemu yokubona ilingana nemboni ye-subassembly, i-router ilingana nomthengisi we-wholesale, futhi iswishi ilingana nomsabalalisi wezinto.Isignali ye-analog edluliselwa ngekhebula lenethiwekhi evamile iguqulwa ibe isignali yedijithali ngemodemu yokubona, bese isignali idluliselwa ku-PC ngomzila.Uma inombolo yama-PC idlula uxhumano lwe-router, udinga ukwengeza iswishi ukuze wandise isikhombimsebenzisi.
Ngokuthuthukiswa kokuxhumana kwe-fiber optical, ingxenye yamamodemu optical asetshenziswa opharetha manje anemisebenzi yomzila.
