SONET (Network yeSynchronous Optical)
SONET inzira yekutumira data nekukurumidza muUnited States. Inoshandisa optical fiber senzira yekutumira data kuti itumire ruzivo rwedhijitari mu ring kana point-to-point layout. Pakati payo, inosanganisa kuyerera kwemashoko kuitira kuti masaini anobva kunzvimbo dzakasiyana agone kuwanda nekukurumidza munzira ye common signal inokurumidza. SONET inomiririrwa nemazinga eOC (optical carrier), akadai seOC-3, OC-12, OC-48, nezvimwewo, uko nhamba dzinomiririra kuwanda kwe OC-1 (51.84 Mbps). SONET architecture yakagadzirwa nekudzivirira kwakasimba uye kugona kuzvigadzirisa, saka inowanzoshandiswa muma network emusana.
SDH (Synchronous Digital Hierarchy)
SDH inonyanya kuenzana neSONET pasi rose, inonyanya kushandiswa muEurope nedzimwe nzvimbo dzisiri dzeUS. SDH inoshandisa STM (Synchronous Transport Module) mazinga kuti ione kumhanya kwakasiyana kwekutumira, senge STM-1, STM-4, STM-16, nezvimwewo, uko STM-1 yakaenzana ne155.52 Mbps. SDH neSONET zvinogona kushanda pamwe chete muzvinhu zvakawanda zvehunyanzvi, asi SDH inopa kuchinjika kwakawanda, sekubvumidza masaini kubva kunzvimbo dzakasiyana kuti asanganiswe nyore nyore mufiber imwe chete ye optical.
DWDM (Dense Wavelength Division Multiplexing)
DWDM itekinoroji yekutumira network ye fiber optic inowedzera bandwidth nekutumira masaini akawanda e optical emawavelength akasiyana panguva imwe chete pa fiber imwe chete ye optical. Masisitimu eDWDM anogona kutakura masaini anopfuura zana emawavelength akasiyana, imwe neimwe inogona kuonekwa senzira yakazvimirira, uye chiteshi chega chega chinogona kutumira pamitengo yakasiyana uye mhando dzedata. Kushandiswa kweDWDM kunobvumira vashandisi ve network kuwedzera kugona kwe network pasina kuisa tambo itsva dze optical, izvo zvakakosha zvikuru kumusika we data service nekukura kukuru kwekudiwa.
Kusiyana pakati pevatatu ava
Kunyangwe matekinoroji matatu aya akafanana mupfungwa, achiri akasiyana pakushandiswa kwawo chaiko:
Mitemo yehunyanzvi: SONET neSDH ndiwo mirairo miviri yehunyanzvi inoenderana. SONET inonyanya kushandiswa kuNorth America, nepo SDH inonyanya kushandiswa mune dzimwe nzvimbo. DWDM inyanzvi yekuwedzera huwandu hwewavelength inoshandiswa pakutumira masaini akawanda akafanana pane mitemo yedata.
Mwero wedata: SONET neSDH zvinotsanangura zvikamu zvemuyero wakatarwa wekutumira data kuburikidza nemazinga kana mamodule chaiwo, nepo DWDM ichinyanya kutarisa pakuwedzera mwero wekutumira data rese nekuwedzera nzira dzekutumira mufiber imwe chete ye optical.
Kuchinjika uye kukura: SDH inopa kuchinjika kwakawanda kupfuura SONET, zvichiita kuti kutaurirana kwenyika dzese kuve nyore, nepo tekinoroji yeDWDM ichipa kuchinjika kukuru uye kukura muhuwandu hwedata uye kushandiswa kwespectrum, zvichibvumira network kuwedzera sezvo kudiwa kuri kukura.
Nzvimbo dzekushandisa: SONET neSDH zvinowanzo shandiswa kuvaka ma network emusana uye masisitimu avo ekudzivirira nekuzvigadzirisa, nepo DWDM iri mhinduro yekutumira network ye optical iri kure uye kure zvakanyanya, inoshandiswa pakubatanidza pakati penzvimbo dzedata kana mumasisitimu emagetsi emugungwa, nezvimwewo.
Muchidimbu, SONET, SDH neDWDM matekinoroji akakosha ekuvaka network dzekutaurirana dze optical fiber dzanhasi nedzemangwana, uye tekinoroji yega yega ine mamiriro ayo akasiyana ekushandisa uye zvakanakira tekinoroji. Nekusarudza nekushandisa matekinoroji aya akasiyana nemazvo, vashandisi venetwork vanogona kuvaka network dzekutumira data dzinoshanda, dzakavimbika uye dzinokurumidza pasi rese.
