Taw qhia txog qhov zoo ntawm PDH optical transceiver

PDH optical transceiver (Plesiochronous Digital Hierarchy, quasi-synchronous digital series) yog lub peev xwm me me optical transceiver, feem ntau ua ke daim ntawv thov, kuj hu ua point-to-point applications, thiab lub peev xwm feem ntau yog 4E1, 8E1, 16E1. Tom ntej no,JHA TECHNOLOGYyuav qhia qhov zoo ntawm pdh optical transceivers kom ntxaws, cia saib!

1. Ib qho kev sib koom ua ke me ntsis thiab tus qauv kev sib koom ua ke muab qhov ua tau rau kev sib cuam tshuam ntawm cov khoom siv los ntawm cov tuam txhab sib txawv.
2. Kev tswj xyuas lub peev xwm hauv network tau txhim kho zoo heev.
3. Muab lub tswv yim tshiab ntawm kev kho tus kheej network. Lub nplhaib network daim ntawv nrog kev tiv thaiv tus kheej muaj peev xwm tsim los ntawm SDH cov cuab yeej tuaj yeem rov pib kev sib txuas lus zoo los ntawm kev kho tus kheej thaum lub teeb liab tseem ceeb ntawm qhov nruab nrab kis tau tus mob raug txiav tawm.
4. Byte multiplexing thev naus laus zis tau txais los ua kom cov ceg ntoo sab sauv thiab sab qis hauv lub network yooj yim heev.

Vim tias PDH muaj qhov zoo tshaj plaws uas tau hais los saum toj no, nws yuav dhau los ua ib qho ntawm cov thev naus laus zis kom paub txog cov ntaub ntawv superhighway. Tab sis ntawm cov ceg txoj kev thiab txoj kev nkhaus txuas nrog cov ntaub ntawv loj, PDH optical transceiver cov cuab yeej tseem yuav pab tau.

Lub 8E1 PDH optical transceiver siv lub tshuab hluav taws xob loj sib txuas nrog kev ywj pheej ntawm cov cuab yeej cuab tam, thiab siv lub sij hawm faib ua ntau yam cuab yeej siv los sib xyaw thiab encode E1 cov cim thiab xa mus rau ntawm ib khub ntawm optical fibers. Cov khoom tsim los siv cov nti no tau txais kev tsim qauv ib leeg, nrog kev sib koom ua ke siab, me me, kev siv hluav taws xob tsawg, kev ua haujlwm txhim khu kev qha, thiab yooj yim installation thiab siv.
