SONET: synchronous optical network, digital transmission standard, yakatangwa muUnited States muna 1988. Chiratidzo chemagetsi che 1 chinotsanangurwa se STS-1, uye chiyero che 1 optical chiratidzo chinoratidzwa seOC-1, ine chiyero che 51.84Mb. /s. Pahwaro uhwu, simudzira kuburikidza nekuwanda kwekuwedzera kuti uvandudze kukurumidza kwekutapurirana uye kutapurirana zvakanaka.Gare gare, ITU-T yakagadzira chiyero chepasi rose chakabatana SDH chinoenderana nechiyero ichi, saka SONET inogona kutorwa sechikamu cheiyo SDH standard.
SONET inotsanangura mana optical interface layer, kubva kumusoro kusvika pasi ndeye:
1. The photon layer (Photonic Layer) inogadzira bhiti transmission mhiri kwetambo yemaziso, uye ine basa rekushandura pakati pemagetsi emagetsi e-synchronous transmission (STS) uye optical signal ye optical carrier (OC). Kukurukurirana kunoitwa nemagetsi-optic converters mune iyi layer.
2. Section layer (Section Layer) inotumira STS-N mafuremu pane optical cable.Ine basa rekugadzira uye kuona kukanganisa.
Iwo matinji maviri ari pamusoro anodiwa, asi maviri anotevera akaturikidzana ane sarudzo.
3. Mutsara wemutsara (Mutsetse weMutsetse) une basa rekugadzirisa nzira yekubatanidza uye kuwandisa, uye kuchengetedzwa kwekutsvaga kwekuchinjana.
4. Iyo nzira layer (Path Layer) inobata nekufambiswa kwemasevhisi pakati peiyo nzira terminal zvishandiso PTE (Path Terminating Element), Paiyi PTE panechinjaneSONET kugona. Iyo nzira yegwara ine zvakare interface kune isiri-SONET network.
Aya maturu mana anogona kunyatsoonekwa sechikamu chechikamu chemuviri muOSI 7 layer modhi, nekuti ese mana akaturikidzana ari muOSI physics layer.
SONET Nzvimbo inowanzoshandiswa ndeyeyero yayo yakatarwa yekufambisa:
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 - inenge 13 Gbit / s
OC-384 - inenge 20 Gbit / s
OC-768 - inenge 40 Gbit / s
OC-1536 - inenge 80 Gbit / s
OC-3072 - inenge 160 Gbit / s
Tiri kutaura nezve synchronous faibha network, sumo yakajairika ndiyo iri pamusoro apa. Kune yakabatana optical fiber network midziyo inobatanidzwa muShenzhen HDV Photoelctron Technology Co., Ltd., yakadai se: ACONU/KukurukuriranaONU/ AkangwaraONU/ Optical faibhaONU/ XPONONU/ GPONONU, kanaOLTseries, transceiver series uye zvichingodaro. Imhando yemidziyo yetiweki, kana paine kudiwa kwevatengi, unogona kudzokera kune peji reimba kuti ubate kambani yedu, uchimirira kuvapo kwako.
