SONET (Synchronous Optical Network)
SONET ndeyekumhanya-mhanya network yekutapurirana mwero muUnited States. Inoshandisa optical fiber senzira yekufambisa kuendesa ruzivo rwedhijitari mumhete kana point-to-point marongero. Papakati payo, inowiriranisa kuyerera kweruzivo kuitira kuti masaini kubva kwakasiyana masosi anogona kuwanziridzwa pasina kunonoka pane yakakwirira-kumhanya yakajairika chiratidzo nzira. SONET inomiririrwa neOC (optical carrier) mazinga, akadai seOC-3, OC-12, OC-48, nezvimwewo, apo nhamba dzinomiririra kuwanda kwechikamu chekutanga OC-1 (51.84 Mbps). SONET architecture yakagadzirwa nekudzivirira kwakasimba uye kugona kuzvidzora, saka inowanzoshandiswa mumambure emusana.
SDH (Synchronous Digital Hierarchy)
SDH ndiyo yakaenzana nedzimwe nyika dzeSONET, inonyanya kushandiswa muEurope nedzimwe nzvimbo dzisiri dzeUS. SDH inoshandisa STM (Synchronous Transport Module) nhanho kuona kumhanya kwakasiyana-siyana, seSTM-1, STM-4, STM-16, nezvimwewo, uko STM-1 yakaenzana ne155.52 Mbps. SDH uye SONET zvinopindirana mune zvakawanda zvehutano, asi SDH inopa kuwedzera kushanduka, zvakadai sekubvumira zviratidzo kubva kune zvakasiyana-siyana zvakasiyana kuti zvive nyore kubatanidzwa mune imwechete optical fiber.
DWDM (Dense Wavelength Division Multiplexing)
DWDM ndeye fiber optic network transmission tekinoroji inowedzera bandwidth nekutumira akawanda masaini masaini eakasiyana wavelengths panguva imwe chete pane imwechete optical fiber. DWDM masisitimu anogona kutakura zvinodarika 100 zviratidzo zvewavelengths dzakasiyana, imwe neimwe inogona kutariswa senge yakazvimiririra chiteshi, uye imwe neimwe chiteshi inogona kuendesa pamatanho akasiyana uye data mhando. Iko kushandiswa kweDWDM kunobvumira vashandisi venetiweki kuwedzera zvakanyanya network network pasina kuisa tambo nyowani dzemaziso, iyo yakakosha zvakanyanya kumusika webasa re data nekukura kwakakura mukudiwa.
Kusiyana pakati pevatatu
Kunyangwe iwo matatu matekinoroji akafanana mufungwa, achiri akasiyana mukushandisa chaiko:
Tekinoroji zviyero: SONET uye SDH zvinonyanya zviviri zvinoenderana tekinoroji zviyero. SONET inonyanya kushandiswa muNorth America, nepo SDH inonyanya kushandiswa mune dzimwe nzvimbo. DWDM iwavelength multiplexing tekinoroji inoshandiswa pakufambisa kwemasaini akawanda akafanana pane kudhirowa data fomati.
Nhamba yedata: SONET uye SDH inotsanangura zvikamu zvakagadziriswa zvekutengesa data kuburikidza nemazinga chaiwo kana ma modules, nepo DWDM inotarisa zvakanyanya pakuwedzera huwandu hwehuwandu hwekutumira data nekuwedzera nzira dzekutumira mune imwechete optical fiber.
Flexibility uye scalability: SDH inopa kuwedzera kushanduka kupfuura SONET, kufambisa kukurukurirana kwenyika dzakawanda, nepo DWDM teknolojia inopa kushanduka kukuru uye scalability muhuwandu hwemashoko uye kushandiswa kwemagetsi, zvichiita kuti network iwedzere sezvo kudiwa kunokura.
Nzvimbo dzekushandisa: SONET uye SDH zvinowanzoshandiswa pakuvaka mambure emusana uye kudzivirira kwavo uye maitiro ekuzvigadzirisa, nepo DWDM iri mhinduro yekufamba-kureba uye ultra-long-kure-kure optical network transmission, inoshandiswa pakubatanidza pakati pe data data kana mhiri kwemakungwa. cable systems, nezvimwewo.
Muchidimbu, SONET, SDH uye DWDM ndiwo matekinoroji akakosha ekuvaka anhasi uye emangwana optical fiber communication network, uye tekinoroji imwe neimwe ine yayo yakasarudzika mamiriro ekushandisa uye hunyanzvi hwakanakira. Nekusarudza nemazvo uye nekushandisa tekinoroji dzakasiyana siyana, vashandisi venetiweki vanogona kuvaka anobudirira, akavimbika uye akakwira-speed ekufambisa data kutenderera pasirese.
