Lebelo le tšireletso ke melemo e 'meli ea SONET
SONET ke theknoloji ea marang-rang ea 'mele e etselitsoeng ho tsamaisa boholo ba sephethephethe ho feta maeto a malelele ho fiber optic cabling . SONET qalong e entsoe ke Setsi sa Melao ea Melao ea Melao ea Amerika ea Melao ea Mehala ea United States bohareng ba bo-1980. Tsamaiso ena ea puisano ea puisano ea digital e fetisa melaetsa e mengata ea litaba ka nako e le 'ngoe.
Sonet Litšoaneleho
SONET e na le litšobotsi tse 'maloa tse etsang hore e ipiletse, ho akarelletsa:
- SONET e hloka lisebelisoa tse fokolang ho feta mekhoa e meng ea lithuto le ho fana ka ts'ebeliso e eketsehileng ea marang-rang
- SONET e hlalosa litekanyetso tse hlakileng tsa ho sebelisana ha lihlahisoa tse fapaneng tsa barekisi.
- SONET e ka jara hoo e batlang e le efe kapa efe e phahameng-protocol e kenyeletsang IP.
- SONET e kenyelletsa tšehetso e keneloang bakeng sa boiketlo ba taolo le tlhokomelo.
- SONET e tšehetsa mefuta eohle ea sephethephethe ho akarelletsa lentsoe, data le video.
- SONET e fana ka tšireletseho e phahameng ho feta mekhoa e meng ea lits'ebeletso.
Tlhokahalo e amohelehang ea SONET ke litšenyehelo tsa eona tse phahameng.
SONET e tloaelehile ho sebelisoa mechineng ea tšebeliso ea morao-rao. E boetse e fumanoa likampong le liofising tsa lifofane.
Tshebetso
SONET e etsa ka lebelo le phahameng haholo. Sebakeng sa pontšo ea motheo, se bitsoang STS-1, SONET se tšehetsa 51.84 Mbps. Ntho e latelang ea SONET e bontšang, STS-3, e tšehetsa mararo a mararo, kapa 155.52 Mbps. Litekanyetso tse phahameng tsa SONET tse bontšang ho eketsa li-bandwidth tse ngata tse latellanang tsa tse 'nè, ho fihlela hoo e ka bang 40 Gbps.
Lebelo la SONET le entse hore theknoloji e be le tlhōlisano le mekhoa e meng e kang Asynchronous Transfer Mode le Gigabit Ethernet ka lilemo tse ngata. Leha ho le joalo, kaha litekanyetso tsa Ethernet li tsoetse pele lilemong tse mashome a mabeli tse fetileng, e fetohile sebaka se ratoang haholo bakeng sa litšebeletso tsa khale tsa SONET.
