PDH optical transceiver (Plesiochronous Digital Hierarchy, quasi-synchronous digital series) ndi transceiver yaing'ono yamagetsi, yomwe nthawi zambiri imagwirizanitsidwa, yomwe imatchedwanso point-to-point applications, ndipo mphamvu nthawi zambiri ndi 4E1, 8E1, 16E1. Ena,JHA TECHNOLOGYiwonetsa zabwino za pdh optical transceivers mwatsatanetsatane, tiyeni tiwone!

1. Mulingo wolumikizana pang'ono ndi mawonekedwe ogwirizana amapereka mwayi wolumikizana pakati pa zida kuchokera kwa opanga osiyanasiyana.
2. Maluso owongolera maukonde awongoleredwa kwambiri.
3. Ikani patsogolo lingaliro latsopano la intaneti yodzichiritsa. Mawonekedwe a netiweki a mphete okhala ndi chitetezo chodzichiritsa okha chopangidwa ndi zida za SDH amatha kuyambiranso kulankhulana kwanthawi zonse kudzera pa netiweki yodzichiritsa yokha pomwe chizindikiro chachikulu cha sing'anga yopatsirana chimadulidwa.
4. Ukadaulo wa Byte multiplexing umatengedwa kuti upangitse ma sign a nthambi apamwamba ndi apansi pamaneti kukhala osavuta.

Chifukwa PDH ili ndi zabwino zomwe tazitchula pamwambapa, ikhala imodzi mwamaukadaulo ofunikira kuzindikira njira yayikulu kwambiri. Koma m'misewu yanthambi ndi misewu ya foloko yolumikizidwa ndi msewu wazidziwitso, zida za PDH Optical transceiver zidzakhalabe zothandiza.

8E1 PDH optical transceiver imagwiritsa ntchito dera lalikulu lophatikizika lomwe lili ndi ufulu wodziyimira pawokha wanzeru, ndipo imagwiritsa ntchito ukadaulo wogawa nthawi kuti usakanikize ndikusindikiza ma siginecha a E1 ndikuwatumiza pawiri ya ulusi wamagetsi. Zopangidwa pogwiritsa ntchito chip iyi zimatengera kapangidwe ka bolodi limodzi, kuphatikiza kwakukulu, kukula kochepa, kugwiritsa ntchito mphamvu zochepa, ntchito yodalirika, kukhazikitsa ndi kugwiritsa ntchito mosavuta.
