I-PDH optical transceiver (i-Plesiochronous Digital Hierarchy, i-quasi-synchronous digital series) iyi-transceiver ebonakalayo enamandla amancane, izinhlelo zokusebenza ezibhanqiwe ngokuvamile, ezibuye zibizwe ngokuthi izinhlelo zokusebenza ze-point-to-point, futhi umthamo ngokuvamile ngu-4E1, 8E1, 16E1. Olandelayo,I-JHA TECHNOLOGYizokwethula izinzuzo ze-pdh optical transceivers ngokuningiliziwe, ake sibheke!

1. Isilinganiso sebhithi esihlanganisiwe nezinga lokusebenzelana elihlanganisiwe linikeza ithuba lokuxhumana phakathi kwamadivayisi avela kubakhiqizi abahlukene.
2. Amakhono okuphatha inethiwekhi athuthukiswe kakhulu.
3. Beka phambili umqondo omusha wenethiwekhi yokuziphilisa. Ifomu lenethiwekhi yendandatho elinekhono lokuzivikela lokuziphilisa elakhiwe ngezinto ze-SDH lingakwazi ukuqalisa kabusha ngokuzenzakalelayo ukuxhumana okuvamile ngenethiwekhi yokuziphilisa lapho isignali eyinhloko yendawo yokudlulisela inqanyuliwe.
4. Ubuchwepheshe be-Byte multiplexing bamukelwa ukwenza amasignali egatsha aphezulu naphansi kunethiwekhi abe lula kakhulu.

Ngenxa yokuthi i-PDH inezinzuzo eziphawulekayo ezibalwe ngenhla, izoba obunye bobuchwepheshe obuyisisekelo ukuze uthole ulwazi lomgwaqo onguthelawayeka omkhulu. Kodwa emigwaqweni yegatsha nasemigwaqweni yemfoloko exhunywe nothelawayeka wolwazi, okokusebenza kwe-PDH optical transceiver kusazoba usizo.

I-8E1 PDH i-optical transceiver isebenzisa isekethe enkulu ehlanganisiwe enamalungelo empahla engqondo ezimele, futhi isebenzisa ubuchwepheshe bokuhlukanisa isikhathi ukuze ihlanganise futhi ihlanganise amasiginali e-E1 futhi iwadlulisele kuma-optical fibers. Imikhiqizo eklanywe kusetshenziswa le chip ithatha idizayini yebhodi elilodwa, enokuhlanganiswa okuphezulu, usayizi omncane, ukusetshenziswa kwamandla okuphansi, umsebenzi othembekile, nokufaka nokusetshenziswa kalula.
