(1) Likhoutu tsa mohloli le li-decoding
Mesebetsi e 'meli ea mantlha: e' ngoe ke ho ntlafatsa katleho ea phetiso ea tlhahisoleseling, ke hore, ka mofuta o mong oa theknoloji ea ho hatella likhoutu ho leka ho fokotsa palo ea matšoao ho fokotsa sekhahla sa matšoao. Ea bobeli ke ho tlatsa phetoho ea analog / digital (A / D), ke hore, ha mohloli oa tlhahisoleseding o fana ka letšoao la analog, mohloli oa encoder o o fetola letšoao la digital ho finyella phetiso ea digital ea letšoao la analog.
(2) Khoutu ea kanale le ho e ngola
Mosebetsi: Taolo ea liphoso. Letšoao la dijithale le tla angoa ke lerata le liphoso tse ling ts'ebetsong ea phetisetso. E le ho fokotsa liphoso, mochine oa encoder le karolo ea boitsebiso bo fetisitsoeng e eketsa likarolo tsa tšireletso (lintho tsa tsamaiso) ho latela melao e itseng ho theha seo ho thoeng ke "anti-interference coding". Decoder ea seteishene qetellong ea ho amohela e khetha ho latela melao e fapaneng e fapaneng ho fumana kapa ho lokisa liphoso le ho ntlafatsa ts'epahalo ea sistimi ea puisano.
(3) Encryption le decryption
E le ho netefatsa ts'ireletso ea tlhahisoleseding e fetisitsoeng, tatellano ea dijithale e ferekanngoa ka mokhoa oa ho fetisoa, ke hore, password e eketsoa, ts'ebetso ena e bitsoa encryption. Ho khutlisa molaetsa oa mantlha ke decryption.
(4) Digital modulation le demodulation
Digital modulation: Maqhubu a maqhubu a lets'oao la dijithale baseband e fetisetsoa ho maqhubu a phahameng ho theha lets'oao la puisano la sehlopha le loketseng ho fetisoa ha mocha. Qetellong ea ho amohela, lets'oao la baseband ea dijithale le ka khutlisoa ka ho theoleloa ho hokahaneng kapa ho theoleloa ho sa lumellaneng.
(5) Kamahanyo
Synchronization: Ke ho boloka matšoao lipheletsong tse peli tsa ho amohela le ho amohela a ntse a tsamaisana ka nako, 'me ke ntho e hlokahalang bakeng sa ho netefatsa mosebetsi o hlophisehileng, o nepahetseng le o tšepahalang oa sistimi ea puisano ea dijithale.
Ena ke Shenzhen HDV phoelectron Technology Ltd. ho u tlisetsa sengoloa sa "mohlala oa sistimi ea puisano", ke tšepa ho u thusa, Shenzhen HDV phoelectron Technology Ltd.ONUletoto, letoto la li-transceiver,OLTletoto, empa hape le tlhahiso ea letoto la lihlooho tse, tse kang: Puisano optical module, optical puisano module, netweke optical module, puisano optical module, optical fiber module, Ethernet optical fiber module, joalo-joalo, e ka fana ka tšebeletso ea boleng bo lumellanang bakeng sa basebelisi ba fapaneng.
