SONET (Umuyoboro wa Optical Network)
SONET ni umuyoboro wihuse wohereza imiyoboro muri Amerika. Ikoresha fibre optique nkikwirakwizwa ryogukwirakwiza amakuru ya digitale mu mpeta cyangwa ku ngingo. Muri rusange, ihuza amakuru atemba kugirango ibimenyetso biva ahantu hatandukanye bishobora kugwizwa nta gutinda kumuvuduko mwinshi wihuta wibimenyetso. SONET ihagarariwe nurwego rwa OC (optique itwara optique), nka OC-3, OC-12, OC-48, nibindi, aho imibare igereranya inshuro nyinshi yibice shingiro OC-1 (51.84 Mbps). Ubwubatsi bwa SONET bwateguwe hamwe nuburinzi bukomeye hamwe nubushobozi bwo kwisubiraho, kubwibyo bukoreshwa kenshi mumiyoboro yinyuma.
SDH (Synchronous Digital Hierarchy)
SDH mubusanzwe ihwanye na SONET mpuzamahanga, ikoreshwa cyane muburayi no mubindi bice bitari Amerika. SDH ikoresha urwego rwa STM (Synchronous Transport Module) kugirango imenye umuvuduko utandukanye wo kohereza, nka STM-1, STM-4, STM-16, nibindi, aho STM-1 ihwanye na 155.52 Mbps. SDH na SONET birashobora gukorana muburyo burambuye bwa tekiniki, ariko SDH itanga byinshi byoroshye, nko kwemerera ibimenyetso biva ahantu henshi kugirango byinjizwe byoroshye muri fibre optique.
DWDM (Igabana ryinshi rya Wavelength Division Multiplexing)
DWDM ni tekinoroji yo gukwirakwiza imiyoboro ya fibre optique yongerera umurongo mugukwirakwiza ibimenyetso byinshi bya optique yuburebure butandukanye icyarimwe icyarimwe kuri fibre optique. Sisitemu ya DWDM irashobora gutwara ibimenyetso birenga 100 byuburebure butandukanye, buri kimwe muri byo gishobora gufatwa nkumuyoboro wigenga, kandi buri muyoboro ushobora kohereza ku bipimo bitandukanye nubwoko bwamakuru. Ikoreshwa rya DWDM ryemerera abakoresha imiyoboro kwagura ubushobozi bwurusobe badashyizeho insinga nshya za optique, zifite agaciro gakomeye kumasoko ya serivise yamakuru hamwe no kwiyongera guturika kubikenewe.
Itandukaniro muri bitatu
Nubwo tekinoroji eshatu zisa mubitekerezo, biracyatandukanye mubikorwa bifatika:
Ibipimo bya tekiniki: SONET na SDH ahanini ni bibiri bya tekiniki bihuye. SONET ikoreshwa cyane muri Amerika ya ruguru, naho SDH ikoreshwa cyane mu tundi turere. DWDM ni tekinoroji yumurongo wa tekinoroji ikoreshwa mugukwirakwiza ibimenyetso byinshi bisa aho kuba ibipimo byimiterere.
Igipimo cyamakuru: SONET na SDH bisobanura ibice byagenwe byogukwirakwiza amakuru binyuze murwego rwihariye cyangwa module, mugihe DWDM yibanda cyane mukwongera igipimo rusange cyo kohereza amakuru wongeyeho imiyoboro yoherejwe muri fibre imwe optique.
Guhindura no kwipimisha: SDH itanga ibintu byoroshye kuruta SONET, yorohereza itumanaho mpuzamahanga, mugihe tekinoroji ya DWDM itanga ihinduka ryinshi nubunini mubipimo byamakuru no gukoresha spekiteri, bigatuma umuyoboro waguka uko ibyifuzo byiyongera.
Ahantu ho gukoreshwa: SONET na SDH zikoreshwa kenshi mukubaka imiyoboro yumugongo no kubarinda no kwisubiraho, mugihe DWDM nigisubizo cyoguhuza intera ndende na ultra-ndende-ya optique yohereza imiyoboro, ikoreshwa muguhuza ibigo byamakuru cyangwa hakurya yubwato. sisitemu ya kabili, nibindi
Muri make, SONET, SDH na DWDM ni tekinoroji yingenzi yo kubaka imiyoboro y'itumanaho ya optique ya none kandi izaza, kandi buri tekinoroji ifite uburyo bwihariye bwo gukoresha hamwe nibyiza bya tekiniki. Muguhitamo neza no gushyira mubikorwa ubwo buhanga butandukanye, abakoresha imiyoboro barashobora kubaka imiyoboro ikora neza, yizewe kandi yihuta yohereza amakuru kwisi yose.
