Hajoale, ka nts'etsopele ea theknoloji ea tlhahisoleseling ea marang-rang, re na le tsebo e tsoetseng pele ea ts'ebeliso ea tekheniki, e 'ngoe ea tsona ke ts'ebeliso eaPdh optical transceivers. Kaha re sebelisitse li-transceivers tsa pdh optical, phetisetso ea tlhahisoleseling e robile haholo mefokolo ea phetiso ea tlhahisoleseling ea setso.

1. Kenyelletso e khutšoanyane ea lisebelisoa tsa PDH optical transceiver

PDH network optical transceiver e amohela lipotoloho tse kholo tse kopaneng tse nang le litokelo tse ikemetseng tsa thepa ea mahlale, ho sebelisa theknoloji ea ho arola nako, ho notlela nako ea dijithale le theknoloji ea ho hula oache, le theknoloji ea anti-interference 2M, e loketseng liketsahalo tse nang le litlhoko tse phahameng tse tšepahalang le tse felletseng. mesebetsi e thusang. Tse kang: China Mobile, China Unicom, mehala ea puisano, matla a motlakase, tšireletso ea sechaba, sesole, litsela tse kholo, lifofane le marang-rang a mang a inehetseng a puisano. Karolo ea hardware e amohela FPGA e kholo, e kopanyang encoding, decoding, ho kenya tlhahisoleseding, le ho fetola alamo, e leng se etsang hore potoloho e be bonolo le ho ntlafatsa ho tšepahala ha mochine oohle.

PDH optical transceiver e kopanya le ho kenya lets'oao la E1 ebe e e fetisetsa ho li-fiber tsa optical. Ts'ebetso ea tsamaiso ea marang-rang ea PDH optical transceiver e nolofalletsa tsamaiso e kopaneng ea lisebelisoa tsa puisano ke basebelisi ba indasteri. Ka tsamaiso e bohareng ea marang-rang, mesebetsi ea tsamaiso e kang ho shebella, ho hlophisa, ho tsosolosa, le ho ntlafatsa ts'ebetso ea lisebelisoa tse hole tse tsamaisanang li ka phethoa.

2. Mesebetsi e ka sehloohong le likarolo tsa PDH optical transceiver

Fana ka sebopeho sa tsamaiso ea marang-rang ea RS232, ts'ehetso ea tsamaiso e kopanetsoeng ea marang-rang; (e sebetsa ho sehlopha sa NT-240D/240D+) phepelo ea matla a mabeli, "backups" e chesang, (e sebetsang ho NT-240D/240D+) e fana ka likou tsa khoebo tsa 4 E1, Recovery oache ea dijithale le theknoloji ea senotlolo sa phasele e boreleli e ka khetha AC220V. , DC48V, DC+24V, DC-24V phepelo ea motlakase ho fana ka tlhokomeliso e felletseng ea alamo ea lehae / ea lithaka, Leseli la mebala e meraro le bontša hore le tšehetsa loopback ea lekala ea sebaka sa E1 / e hole, e fana ka mohala o le mong oa molao, e fana ka mocha oa data oa RS232 o hlakileng, 'me tekanyo ke 300-19.2Kbit / s adaptive.

3. Mosebetsi oa PDH optical transceiver

a. Phetiso ea E1: Sehlahisoa se ka lemoha 4-16 E1 (2Mb / s) phetiso ea fiber optical.

phetiso ea b.Ethernet: ka mochine oa Ethernet oa boikhethelo, likanale tse 'nè tsa 10M / 100M adaptive Ethernet tšebeletso ea optical fiber transmission e ka phethahala.

c.Tšebeletso ea tšebeletso: Sehlahisoa se ka hlomelloa ka ts'ebetso ea thelefono ea tšebeletso ho hlokomela puisano ea khoebo pakeng tsa li-transceivers tse peli tsa optical.

d.RS232 data: Sehlahisoa se fana ka mocha oa data oa RS232 asynchronous. Sekhahla sa data se ikamahanya le maemo ka tlase ho 115.2Kb/s, 'me sebopeho sa data se ikamahanya le maemo.

f.Switch quantity interface: Sehlahisoa se ka hlomelloa ka relay output switch quantity interface, e ka sebelisoang bakeng sa alamo kapa taolo.
