I-Optical Transceiver iyisisetshenziswa esibulalayo sokudlulisa isignali yokubona.Ama-transceivers optical kufanele ahlukaniswe abe ama-transceiver optical ocingo, ama-transceivers optical video, ama-audio optical transceivers, ama-transceiver optical data, ama-Ethernet optical transceivers, nama-transceivers optical abe yizigaba ze-3: PDH, SPDH, SDH.

I-SDH (i-Synchronous Digital Hierarchy, Synchronous Digital Hierarchy), ngokusho kwencazelo enconyiwe ye-ITU-T, ukudluliselwa kwamasignali edijithali ngesivinini esihlukile ukuze kuhlinzekwe izinga elihambisanayo lesakhiwo solwazi, okuhlanganisa izindlela zokuphindaphinda, izindlela zemephu, nezindlela zokuvumelanisa ezihlobene. .Uhlelo lobuchwepheshe.

I-SDH optical transceiverinomthamo omkhulu, ngokuvamile i-16E1 kuya ku-4032E1.Manje esetshenziswa kabanzi kumanethiwekhi optical, i-SDH optical terminal iwuhlobo lwemishini yokugcina esetshenziswa kumanethiwekhi okukhanya.

Ukusetshenziswa okuyinhloko kwe-SDH optical transceiver
Imishini yokudlulisa i-SDH ithuthukiswe kakhulu endaweni ebanzi yenethiwekhi kanye nenkundla yenethiwekhi yangasese.Ama-opharetha e-Telecom afana ne-China Telecom, i-China Unicom, ne-Radio ne-Televishini sebevele bakhe amanethiwekhi okudlulisa amehlo asekelwe ku-SDH ngezinga elikhulu.

Ama-opharetha asebenzisa amalophu e-SDH amakhulu ukuze aphathe izinsizakalo ze-IP, izinsiza ze-ATM, kanye nemishini yokufinyelela ehlanganisiwe ye-fiber optical noma baqashise amasekhethi ngokuqondile emabhizinisini nasezikhungweni.

Amanye amanethiwekhi ayimfihlo amakhulu aphinde asebenzise ubuchwepheshe be-SDH ukusetha amalophu optical we-SDH ngaphakathi kwesistimu ukuze aphathe izinsiza ezihlukahlukene.Isibonelo, isistimu yamandla isebenzisa amalophu e-SDH ukuze iphathe idatha yangaphakathi, isilawuli kude, ividiyo, izwi namanye amasevisi.
