SONET: isku xirka indhaha, halbeegga gudbinta dhijitaalka ah, waxaa lagu soo bandhigay Mareykanka 1988. Heerka 1 signalka korantada waxaa lagu tilmaamaa STS-1, heerka 1 signalka indhaha waxaa lagu tilmaamaa sida OC-1, oo leh 51.84Mb / s. Iyada oo ku saleysan tan, kor u qaadida iyada oo loo marayo isku-dhufashada si loo hagaajiyo xawaaraha gudbinta iyo waxtarka gudbinta. Kadib, ITU-T waxay dejisay halbeegga caalamiga ah ee SDH ee midaysan iyadoo lagu saleynayo heerkan, sidaas darteed SONET waxaa loo arki karaa qayb ka mid ah heerka SDH.
SONET waxa ay qeexaysaa afar lakab oo indho-sarcaad ah, kor ilaa hoos waa:
1. Lakabka sawir-qaadista (Lakabka Sawirka) wuxuu socodsiiyaa gudbinta yara ee fiilada indhaha, wuxuuna mas'uul ka yahay beddelka u dhexeeya calaamadda korantada ee gudbinta isku-dhafka ah (STS) iyo calaamadda indhaha ee sidaha indhaha (OC). Isgaadhsiinta waxaa sameeya beddelayaasha korantada-optic ee lakabkan.
2. Lakabka qaybta (Lakabka Qaybta) waxa uu ku gudbiyaa xargaha STS-N ee fiilada indhaha.Waxay leedahay shaqada qaabaynta iyo ogaanshaha qaladka
Labada lakab ee sare waa lagama maarmaan, laakiin labada lakab ee soo socda waa ikhtiyaari.
3. Lakabka khadka (Lakabka Lakabka) ayaa mas'uul ka ah isku-xirka lakabka dariiqa iyo isku-dhufashada, iyo ilaalinta tooska ah ee sarrifka.
4. Lakabka waddada (Lakabka Waddada) wuxuu ka shaqeeyaa gudbinta adeegyada u dhexeeya aaladaha terminaalka waddada PTE (Path Terminating Element), PTE-kan waabeddelooo leh awood SONET. Lakabka dariiqa waxa kale oo uu leeyahay isdhexgal shabakadaha aan SONET ahayn.
Afartan lakab ayaa dhab ahaantii loo arki karaa qayb-hoosaad ka mid ah lakabka jireed ee qaabka lakabka OSI 7, sababtoo ah dhammaan afarta lakab waxay ku yaalaan lakabka fiisigiska OSI.
SONET Barta inta badan la isticmaalo waa heerka gudbinta ee la cayimay:
OC-1 - 51.84Mbit/s
OC-3 - 155.52 Mbit/s
OC-12 - 622.08 Mbit/s
OC-24 - 1.244 Gbit/s
OC-48 - 2.488 Gbit/s
OC-96 - 4.976 Gbit/s
OC-192 - 9.953 Gbit/s
OC-256 — qiyaastii 13 Gbit/s
OC-384 - qiyaastii 20 Gbit/s
OC-768 - qiyaastii 40 Gbit/s
OC-1536 - qiyaastii 80 Gbit/s
OC-3072 - qiyaastii 160 Gbit/s
Waxaan ka hadleynaa shabakadaha fiber synchronous, hordhaca guud waa content kor ku xusan.Wixii la xiriira qalabka network fiber indhaha ku lug leh Shenzhen HDV Photoelctron Technology Co., Ltd., sida: ACONU/XiriirkaONU/ Indheer garadONU/ Fiber indhahaONU/ XPONONU/ GPONONU, amaOLTtaxane, taxane transceiver iyo wixii la mid ah. Ma yihiin nooc ka mid ah qalabka shabakada, haddii ay jirto baahi loo qabo macaamiisha, waxaad ku noqon kartaa bogga guriga si aad ula xiriirto shirkaddayada, sugitaanka joogitaankaaga.
