Optical transceiver yog cov khoom siv davhlau ya nyob twg rau cov teeb liab kis tau tus mob. Optical transceivers yuav tsum tau muab faib ua xov tooj optical transceivers, video optical transceivers, audio optical transceivers, cov ntaub ntawv kho qhov muag transceivers, Ethernet optical transceivers, thiab optical transceivers rau 3 pawg: PDH, SPDH, SDH.

SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy), raws li cov ntsiab lus pom zoo ntawm ITU-T, yog kev sib kis ntawm cov teeb liab ntawm qhov sib txawv ntawm qhov sib txawv los muab cov txheej txheem sib txuas ntawm cov ntaub ntawv, suav nrog cov txheej txheem multiplexing, daim ntawv qhia, thiab lwm yam synchronization txoj kev. . Technical system.

SDH optical transceivermuaj peev xwm loj, feem ntau 16E1 txog 4032E1. Tam sim no dav siv nyob rau hauv optical networks, SDH kho qhov muag davhlau ya nyob twg yog ib yam ntawm cov khoom siv davhlau ya nyob twg siv nyob rau hauv kho qhov muag tes hauj lwm.

Daim ntawv thov tseem ceeb ntawm SDH optical transceiver
SDH cov khoom siv kis tau tus mob tau tsim kho zoo heev hauv thaj chaw dav dav thiab thaj chaw ntiag tug network. Cov neeg ua haujlwm hauv xov tooj xws li Tuam Tshoj Telecom, China Unicom, thiab Xov Tooj Cua thiab TV tau tsim SDH-raws li pob txha kho qhov muag sib txuas ntawm qhov loj.

Cov neeg ua haujlwm siv lub peev xwm loj SDH lub voj voog los nqa cov kev pabcuam IP, ATM cov kev pabcuam, thiab cov khoom siv fiber ntau sib xyaw ua ke lossis xa ncaj qha mus rau cov tuam txhab thiab cov chaw haujlwm.

Qee lub network ntiag tug loj kuj tseem siv SDH thev naus laus zis los teeb tsa SDH kho qhov muag loops nyob rau hauv lub kaw lus kom nqa ntau yam kev pabcuam. Piv txwv li, lub zog hluav taws xob siv SDH loops los nqa cov ntaub ntawv sab hauv, tswj chaw taws teeb, yees duab, suab thiab lwm yam kev pabcuam.
