SONET: umuyoboro wa optique wa optique, urwego rwohereza ibyuma bya digitale, watangijwe muri Reta zunzubumwe zamerika muri 1988. Ikimenyetso cyamashanyarazi yo murwego rwa 1 cyiswe STS-1, naho ikimenyetso cya optique cyo murwego rwa 1 cyiswe OC-1, gifite umuvuduko wa 51.84Mb / s.Hashingiwe kuri ibyo, kuzamura binyuze muri multiplexing kugirango wongere umuvuduko wo kohereza no kohereza neza.Nyuma, ITU-T yashyizeho urwego mpuzamahanga ruhuriweho na SDH rwisi rushingiye kuri iki gipimo, bityo SONET irashobora gufatwa nkigice cya SDH.
SONET isobanura ibice bine bya optique, kuva hejuru kugeza hasi ni:
1. Igice cya Photon (Photonic Layer) gitunganya itumanaho rya biti hejuru ya kabili ya optique, kandi ishinzwe guhinduka hagati yikimenyetso cyamashanyarazi cyogukwirakwiza (STS) hamwe nikimenyetso cya optique yikigo (OC).Itumanaho rikorwa na electro-optique ihindura muriki cyiciro.
2. Igice cyigice (Igice cya Layeri) cyohereza amakadiri ya STS-N kumurongo wa optique. Ifite umurimo wo gushiraho no gutahura amakosa
Ibice bibiri byavuzwe haruguru birakenewe, ariko ibice bibiri bikurikira birakenewe.
3. Umurongo wumurongo (Umurongo wumurongo) ushinzwe inzira yinzira yoguhuza no kugwiza, no kurinda byikora guhana.
4. Inzira yinzira (Inzira yinzira) ikorana nogukwirakwiza serivisi hagati yinzira yanyuma yinzira ya PTE (Inzira yo Kurangiza Inzira), Kuri iyi PTE ni switch ifite ubushobozi bwa SONET.Inzira yinzira nayo ifite intera kumurongo utari SONET.
Izi nzego enye zirashobora kugaragara mubyukuri nkigice cyurwego rwumubiri muburyo bwa OSI 7, kubera ko ibice bine byose biherereye mubice bya fiziki ya OSI.
SONET Ingingo ikoreshwa cyane ni igipimo cyayo cyo kohereza:
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 - hafi 13 Gbit / s
OC-384 - hafi 20 Gbit / s
OC-768 - hafi 40 Gbit / s
OC-1536 - hafi 80 Gbit / s
OC-3072 - hafi 160 Gbit / s
Turimo tuvuga imiyoboro ya fibre ihuza, intangiriro rusange nibiri hejuru.Ku bikoresho bifitanye isano na optique ya fibre optique ifitanye isano na Shenzhen HDV Photoelctron Technology Co., Ltd., nka: ACONU/ ItumanahoONU/ UbwengeONU/ Fibre optiqueONU/ XPONONU/ GPONONU, cyangwa OLT ikurikirana, transceiver ikurikirana nibindi.Nubwoko bwibikoresho byurusobe, niba hari ibikenewe kubakiriya, urashobora gusubira kurupapuro rwurugo kugirango ubaze sosiyete yacu, utegereje ko uhari.
