I-transceiver ye-Optical sisixhobo se-terminal sosasazo lwe-optical signal.I-transceivers optical kufuneka ihlulwe kwii-transceivers optical phone, i-video optical transceivers, i-audio optical transceivers, i-data optical transceivers, i-Ethernet transceivers optical, kunye ne-optical transceivers kwiindidi ze-3: PDH, SPDH, SDH.

I-SDH (i-Synchronous Digital Hierarchy, i-Synchronous Digital Hierarchy), ngokwenkcazo ecetyiswayo ye-ITU-T, ukuhanjiswa kweempawu zedijithali kwizantya ezahlukeneyo ukubonelela ngenqanaba elihambelanayo lolwakhiwo lolwazi, kubandakanywa iindlela zokuphindaphinda, iindlela zokwenza imephu, kunye neendlela ezinxulumene nokuvumelanisa. .Inkqubo yobugcisa.

I-SDH i-transceiver ebonakalayoinomthamo omkhulu, ngokubanzi 16E1 ukuya 4032E1.Ngoku isetyenziswa ngokubanzi kuthungelwano lwe-optical network, i-SDH optical terminal luhlobo lwezixhobo zetheminali ezisetyenziswa kuthungelwano lwamehlo.

Usetyenziso oluphambili lwe-SDH optical transceiver
Izixhobo zothumelo lwe-SDH ziphuhliswe kakhulu kwindawo ebanzi yothungelwano lwendawo kunye nenkundla yenethiwekhi yabucala.Abaqhubi be-Telecom njenge-China Telecom, i-China Unicom, kunye ne-Radio kunye neTelevishini sele bakha i-SDH-based backbone network network transmission transmission kwizinga elikhulu.

Abaqhubi basebenzisa iilophu zeSDH ezinkulu zokuthwala iinkonzo ze-IP, iinkonzo ze-ATM, kunye nezixhobo zokufikelela ezidibeneyo ze-fiber optical okanye ukuqeshisa ngokuthe ngqo iisekethe kumashishini nakumaziko.

Ezinye iinethiwekhi zabucala ezinkulu zikwasebenzisa iteknoloji yeSDH ukuseta iilophu ze-SDH zokukhanya ngaphakathi kwisistim ukuthwala iinkonzo ezahlukeneyo.Ngokomzekelo, inkqubo yamandla isebenzisa iilophu ze-SDH ukuthwala idatha yangaphakathi, ukulawula kude, ividiyo, ilizwi kunye nezinye iinkonzo.
