PDH opitika transceiver (Plesiochronous Digital Hierarchy, quasi-synchronous numera numera) o se transceiver opitika laʻititi, e masani ona faʻapipiʻi faʻaoga, e taʻua foi o tusi-to-point, ma o le gafatia e masani lava 4E1, 8E1, 16E1. Sosoo ai,JHA TECHNOLOGYo le a faʻaalia le lelei o pdh optical transceivers i auiliiliga, seʻi o tatou tilotilo!

1. O se fua fa'atatau tu'ufa'atasi ma se fa'ata'ita'iga tu'ufa'atasia tu'ufa'atasia e maua ai le avanoa mo feso'ota'iga i le va o masini mai le gaosiga eseese.
2. Ua matua'i fa'aleleia atili le fa'aogaina o feso'otaiga.
3. Tuʻu i luma se manatu fou o fesoʻotaʻiga faʻamalolo a le tagata lava ia. O le fomu feso'ota'iga mama ma le malosi o le puipuia o le tagata lava ia e aofia ai meafaigaluega SDH e mafai ona toe amata fa'afeso'ota'i masani e ala i feso'ota'iga fa'amalologa a le tagata lava ia pe a motusia le fa'ailoga autu o le ala fa'asalalau.
4. Byte multiplexing tekinolosi ua faʻaaogaina e faʻafaigofie ai faʻailoga pito i luga ma lalo lala i le fesoʻotaʻiga.

Talu ai ona o le PDH o loʻo i ai faʻamanuiaga mataʻina o loʻo taʻua i luga, o le a avea ma se tasi o tekinolosi faʻavae e iloa ai le faʻamatalaga superhighway. Ae i luga o auala lala ma magaala auala e fesoʻotaʻi ma le auala tele faʻamatalaga, o le PDH opitika transceiver meafaigaluega o le a aoga pea.

O le 8E1 PDH opitika transceiver faʻaaogaina se taʻaloga tuʻufaʻatasia faʻatasi ma aia tatau faʻapitoa tau le atamai, ma faʻaogaina le taimi faʻavasegaina o tekonolosi e faʻafefiloi ma faʻailoga E1 faailoilo ma tuʻuina atu i luga o se pea fibers. O oloa na faʻatulagaina e faʻaaoga ai lenei vaʻa faʻaaogaina se mamanu laupapa e tasi, faʻatasi ai ma le maualuga o le tuʻufaʻatasia, laʻititi laʻititi, maualalo le mana faʻaaogaina, galuega faʻalagolago, ma faigofie faʻapipiʻi ma faʻaoga.
