Programmable ASIC e shebana le mesebetsi e mengata ho chip e le 'ngoe,' me e na le melemo ea moralo o bonolo, ts'epo e phahameng, le tšebeliso e tlase ea matla, e ka nolofalletsang lisebelisoa ho fumana ts'ebetso e phahameng le litšenyehelo tse tlase.
5. Thepa ea tsamaiso ea marang-rang e ka fana ka tlhahlobo ea marang-rang, ntlafatso, tlaleho ea boemo, tlaleho ea boemo bo sa tloaelehang le mesebetsi ea ho laola, 'me e ka fana ka tlaleho e feletseng ea ts'ebetso le tlaleho ea alamo.
6. Lisebelisoa tsa mofuta oa rack li ka fana ka ts'ebetso e chesang e chesang bakeng sa tlhokomelo e bonolo le ho ntlafatsa ho sa sitisoe.
7. Tšehetsa sebaka se felletseng sa phetiso (0～120km).
8. Lisebelisoa tse ngata li amohela moralo oa phepelo ea matla a 1 + 1, e ts'ehetsa motlakase oa motlakase o pharalletseng, mme o hlokomela ts'ireletso ea phepelo ea motlakase le ho fetoha ha othomathike.
1.3Sehlopha sa li-transceivers tsa fiber optic
Ho na le mefuta e mengata ea li-transceivers tsa fiber optic, 'me mefuta ea tsona e fetoha ho latela mekhoa e fapaneng ea lihlopha.
Ho ea ka tlhaho ea fiber, e ka aroloa ka mefuta e mengata ea fiber transceiver le single-mode fiber transceiver. Ka lebaka la likhoele tse fapaneng tsa optical tse sebelisoang, sebaka sa phetiso ea transceiver se fapane. Sebaka se akaretsang sa phetisetso ea li-transceivers tsa mefuta e mengata e pakeng tsa 2 kilometers le 5 kilometers, ha ho koaheloa ha li-transceivers tsa mofuta o le mong ho ka tloha ho lik'hilomithara tse 20 ho isa ho 120;
Ho ea ka fiber e hlokahalang ea optical, e ka aroloa ka fiber e le 'ngoe ea optical fiber transceiver: lintlha tse rometsoeng le tse amoheloang li fetisoa ka fiber e le' ngoe ea optical; the dual-fiber optical fiber transceiver: data e amohetsoeng le e rometsoeng e fetisoa ka para ea optical fibers.
Ho ea ka boemo ba ho sebetsa / tekanyo, e ka aroloa ka 10M e le 'ngoe, 100M fiber optic transceivers, 10 / 100M adaptive fiber optic transceivers le 1000M fiber optic transceivers. Ho ea ka sebopeho, e ka aroloa ka li-transceivers tsa fiber optic tsa desktop (e ikemetseng) le li-transceivers tsa fiber optic tse kentsoeng ka rack. Desktop optical fiber transceiver e loketse mosebelisi a le mong, joalo ka ho kopana le uplink e le 'ngoe phasejeng. Li-transceivers tsa rack-mounted (modular) fiber optic li loketse ho bokella basebelisi ba bangata. Mohlala, kamore e bohareng ea komporo ea sechaba e tlameha ho kopana le li-switches tsohle sechabeng.
z ho ea ka tsamaiso ea marang-rang, e ka aroloa ka mefuta ea tsamaiso ea marang-rang ea optical fiber transceiver le mofuta oa tsamaiso e seng ea marang-rang oa optical fiber transceiver.
Ho ea ka mofuta oa tsamaiso, e ka aroloa ka tsamaiso e seng ea marang-rang ea Ethernet fiber optic transceivers: plug le play, beha mokhoa oa ho sebetsa oa koung ea motlakase ka sesebelisoa sa ho daela sa hardware. Mofuta oa tsamaiso ea marang-rang Ethernet fiber optic transceiver: ts'ehetso ea tsamaiso ea marang-rang ea carrier-grade
Ho ea ka mofuta oa phepelo ea matla, e ka aroloa ka li-transceivers tsa fiber optic tse hahiloeng ka har'a matla: lisebelisoa tsa motlakase tse hahelletsoeng ka har'a lisebelisoa ke lisebelisoa tsa matla a carrier-grade; li-transceivers tsa kantle tsa fiber optic: lisebelisoa tsa motlakase tsa kantle li sebelisoa haholo lisebelisoa tsa sechaba. Monyetla oa pele ke hore o khona ho ts'ehetsa motlakase oa phepelo ea motlakase o pharalletseng, ho hlokomela ho tsitsisa ha motlakase, ho sefa le ts'ireletso ea matla a lisebelisoa, le ho fokotsa lintlha tsa ho hloleha ka ntle tse bakoang ke ho ikopanya le mochini; molemo oa ho qetela ke hore thepa e nyenyane ka boholo le theko e tlaase.
E arotsoe ke mokhoa oa ho sebetsa, mokhoa o feletseng oa duplex (full duplex) e bolela hore ha ho romela le ho amohela data ho aroloa ka mela e 'meli e fapaneng ea phetisetso, mahlakore ka bobeli a puisano a ka romela le ho amohela ka nako e le' ngoe. Mofuta ona oa phetisetso Mokhoa o na le duplex e felletseng, mme mokhoa o felletseng oa duplex ha o hloke ho chencha tataiso, ka hona ha ho na ho lieha ha nako ho bakoang ke ts'ebetso ea switching;
Half duplex e bolela tšebeliso ea mohala o tšoanang oa phetiso bakeng sa ho amohela le ho romela. Le hoja data e ka fetisoa ka litsela tse peli, mahlakore ka bobeli a puisano a ke ke a romela le ho amohela data ka nako e le 'ngoe. Mokhoa ona oa phetisetso ke halofo ea duplex.
Ha mokhoa oa halofo-duplex o amoheloa, mochine o fetisang le ho amohela pheletsong e 'ngoe le e' ngoe ea mokhoa oa puisano o fetisetsoa moleng oa puisano ka sesebelisoa sa ho amohela / ho romela ho fetola tataiso. Ka hona, nako ea ho lieha e tla etsahala.
