PDH optical transceiver (Plesiochronous Digital Hierarchy, quasi-synchronous digital series) ke transceiver ea optical e nang le bokhoni bo bonyenyane, e atisang ho kopanngoa, e boetse e bitsoa lits'ebetso tsa ntlha-to-point, 'me bokhoni ka kakaretso ke 4E1, 8E1, 16E1. E 'ngoe,JHA THEKNOLOJIe tla hlahisa melemo ea pdh optical transceivers ka botlalo, ha re shebeng!

1. Sekhahla se kopaneng sa biti le maemo a kopaneng a sehokelo se fana ka monyetla oa ho hokahanya lisebelisoa tse tsoang ho bahlahisi ba fapaneng.
2. Bokhoni ba tsamaiso ea marang-rang bo matlafalitsoe haholo.
3. Beha maikutlo a macha a marang-rang a ho ipholisa. Foromo ea marang-rang ea lesale e nang le bokhoni ba ho itšireletsa bo entsoeng ka thepa ea SDH e ka boela ea tsosolosa puisano e tloaelehileng ka marang-rang a ho ipholisa ha pontšo e kholo ea mochine oa phetisetso e khaotsoe.
4. Theknoloji ea li-Byte multiplexing e amoheloa ho etsa hore matšoao a makala a holimo le a tlaase a marang-rang a be bonolo haholo.

Hobane PDH e na le melemo e tsotehang e boletsoeng ka holimo, e tla fetoha e 'ngoe ea mahlale a mantlha a ho lemoha litaba tse kholo. Empa litseleng tsa makala le litseleng tsa fereko tse amanang le tsela e kholo ea boitsebiso, lisebelisoa tsa PDH optical transceiver li ntse li tla ba molemo.

8E1 PDH optical transceiver e sebelisa potoloho e kholo e kopantsoeng e nang le litokelo tse ikemetseng tsa thepa ea mahlale, 'me e sebelisa theknoloji ea ho arola nako ea nako ho kopanya le ho kopanya lipontšo tsa E1 le ho li fetisetsa ka li-fiber tsa optical. Lihlahisoa tse entsoeng ka ho sebelisa chip ena li nka moralo oa boto e le 'ngoe, ka kopanyo e phahameng, boholo bo nyane, tšebeliso e tlase ea matla, mosebetsi o tšepahalang, le ho kenya le ho sebelisoa habonolo.
