Transceiver ea optical ke sesebelisoa sa terminal bakeng sa phetiso ea mats'oao a mahlo.Li-transceivers tsa optical li lokela ho aroloa ka li-transceivers tsa optical tsa thelefono, li-transceivers tsa optical video, li-audio optical transceivers, li-transceivers optical data, Ethernet optical transceivers, le li-transceivers optical likarolong tsa 3: PDH, SPDH, SDH.

SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy), ho ea ka tlhaloso e khothalletsoang ea ITU-T, ke ho fetisoa ha lipontšo tsa digital ka lebelo le fapaneng ho fana ka boemo bo lumellanang ba sebopeho sa tlhahisoleseding, ho akarelletsa le mekhoa ea multiplexing, mekhoa ea 'mapa, le mekhoa e amanang le ho lumellana. .Sistimi ea tekheniki.

SDH optical transceivere na le bokhoni bo boholo, ka kakaretso 16E1 ho 4032E1.Hajoale e sebelisoa haholo marang-rang a optical, SDH optical terminal ke mofuta oa lisebelisoa tsa terminal tse sebelisoang marang-rang a optical.

Tšebeliso e ka sehloohong ea SDH optical transceiver
Thepa ea phetisetso ea SDH e ntlafalitsoe haholo sebakeng se pharaletseng sa marang-rang le sebaka sa marang-rang sa poraefete.Basebelisi ba thelevishene ba kang China Telecom, China Unicom, le Radio le Televishene ba se ba ntse ba hahile marang-rang a SDH-based backbone optical transmission ka tekanyo e kholo.

Basebelisi ba sebelisa lisebelisoa tse kholo tsa SDH ho tsamaisa lits'ebeletso tsa IP, lits'ebeletso tsa ATM, le lisebelisoa tsa phihlello tse kopaneng tsa fiber kapa ho hira lipotoloho ka kotloloho ho likhoebo le litsi.

Likhokahano tse ling tsa poraefete tse kholo li boetse li sebelisa theknoloji ea SDH ho theha SDH optical loops ka har'a sistimi ho tsamaisa lits'ebeletso tse fapaneng.Ka mohlala, tsamaiso ea matla e sebelisa li-loops tsa SDH ho tsamaisa data ea ka hare, taolo ea hōle, video, lentsoe le litšebeletso tse ling.
