Ha merero e fokolang ea hona joale e kopana le phetisetso ea nako e telele, hangata ho sebelisoa fiber optics. Hobane sebaka sa phetiso ea fiber ea optical e telele haholo, ka kakaretso, sebaka sa phetisetso ea fiber ea mofuta o le mong e feta lik'hilomithara tse 10, 'me sebaka sa phetiso ea fiber ea mefuta e mengata e ka fihla ho 2 km.
Marang-rang a fiber optic, hangata re sebelisa li-transceivers tsa fiber optic. Kahoo, ho hokela li-transceivers tsa fiber optic joang? Ha re shebeng hammoho.
Taba ea pele, karolo ea li-transceivers tsa fiber optic
① Transceiver ea optical fiber e ka eketsa sebaka sa phetisetso ea Ethernet le ho holisa radius ea tšireletso ea Ethernet.
② The optical fiber transceiver canswitjhapakeng tsa 10M, 100M kapa 1000M Ethernet segokanyimmediamentsi sa sebolokigolo le segokanyimmediamentsi sa sebolokigolo optical.
③ Ho sebelisa li-transceivers tsa fiber optic ho haha marang-rang ho ka boloka matsete a marang-rang.
④ Li-transceivers tsa fiber optical li etsa hore khokahano lipakeng tsa li-server, li pheta-pheta, li-hubs, liteishene le liteishene li potlake.
⑤ Optical fiber transceiver e na le microprocessor le sebopeho sa ho hlahloba, se ka fanang ka lintlha tse fapaneng tsa ts'ebetso ea lihokelo tsa data.
Ea bobeli, transceiver ea optical e na le transceiver efe, hona e amohela efe?
Ha u sebelisa li-transceiver tsa optical fiber, metsoalle e mengata e tla kopana le lipotso tse joalo:
1.Na li-transceivers tsa fiber optical li lokela ho sebelisoa ka bobeli?
2.Na transceiver ea fiber ea optical e arotsoe ka e 'ngoe bakeng sa ho amohela le e' ngoe bakeng sa ho fetisetsa? Kapa na ho ka sebelisoa li-transceiver tse peli feela e le para?
3. Haeba li-transceivers tsa fiber optical li tlameha ho sebelisoa ka bobeli, na hoa hlokahala hore li be tsa mofuta o tšoanang le mohlala? Kapa na ho na le mefuta e ka sebelisoang hammoho?
Karabo: Li-transceivers tsa fiber optic hangata li sebelisoa ka bobeli e le lisebelisoa tsa ho fetola lifoto, empa hape hoa khoneha ho kopanya li-transceivers tsa fiber optic le fiber.li-switches, li-transceivers tsa fiber optic le li-transceivers tsa SFP. Ha e le hantle, ha feela optical transmission wavelength e ts'oana The signal encapsulation format e ts'oana 'me ka bobeli ba tšehetsa protocol e itseng ho finyella puisano ea optical fiber.
Ka kakaretso, li-fiber tse peli tsa mode e le 'ngoe (li-fiber tse peli li hlokahala bakeng sa puisano e tloaelehileng) li-transceivers ha li aroloe ka ho qetela le ho amohela,' me li ka sebelisoa hafeela li hlaha ka bobeli.
Ke transceiver e nang le fiber e le 'ngoe feela (fiber e le' ngoe e hlokahalang bakeng sa puisano e tloaelehileng) e tla ba le qetello ea ho fetisa le ho amohela.
Ka mantsoe a mang, litekanyetso tse fapaneng (100M le Gigabit) le maqhubu a fapaneng a maqhubu (1310nm le 1300nm) ha li khone ho buisana. Ho phaella moo, esita le haeba transceiver e le 'ngoe ea fiber le fiber tse peli tsa mofuta o le mong li kopantsoe, ho ke ke ha khoneha ho buisana. Interoperable.
Kahoo potso ke hore, transceiver ea fiber e le 'ngoe ke eng le hore na transceiver ea fiber e habeli ke efe? Phapano ke efe pakeng tsa bona?
Transceiver ea fiber e le 'ngoe ke eng? Transceiver ea dual-fiber ke eng?
Transceiver ea fiber e le 'ngoe e bua ka thapo ea optical ea mofuta o le mong. Transceiver e nang le fiber e le 'ngoe e sebelisa konokono e le' ngoe feela 'me lipheletsong ka bobeli li hokahane le motheo ona. Li-transceivers lipheletsong ka bobeli li sebelisa li-wavelengths tse fapaneng tsa optical, kahoo li ka fetisoa ka lets'oao le le leng la mantlha la Leseli.
Transceiver ea li-fiber tse peli e sebelisa li-cores tse peli, e 'ngoe bakeng sa phetiso le e' ngoe bakeng sa ho amohela, 'me ntlha e' ngoe e tlameha ho kenngoa ka lehlakoreng le leng, 'me lipheletso tse peli li tlameha ho tšeloa.
1.Single fiber transceiver
Transceiver ea fiber e le 'ngoe e tlameha ho kenya tšebetsong tšebetso ea ho fetisa le ea ho amohela. E sebelisa theknoloji ea "wavelength division multiplexing" ho fetisa le ho amohela lipontšo tse peli tsa optical tse nang le maqhubu a fapaneng ho fiber e le 'ngoe ea optical.
Ka hona, transceiver ea single-mode-single-fiber e fetisoa ka fiber ea mantlha ea optical, kahoo leseli le fetisang le ho amohela li fetisoa ka mokokotlo oa fiber ka nako e le 'ngoe. Tabeng ena, ho finyella puisano e tloaelehileng, maqhubu a mabeli a leseli a tlameha ho sebelisoa ho khetholla.
Ka hona, mochine oa optical oa transceiver e le 'ngoe ea fiber e le' ngoe e na le maqhubu a mabeli a khanya e hlahisoang, hangata 1310nm / 1550nm. Ka tsela ena, ho na le phapang lipakeng tsa lipheletso tse peli tsa li-transceivers:
Transceiver ka lehlakoreng le leng e fetisetsa 1310nm mme e amohela 1550nm.
Qetello e 'ngoe ke ho ntša 1550nm le ho amohela 1310nm.
Kahoo ho bonolo hore basebelisi ba khetholle, 'me ka kakaretso ba sebelise litlhaku ho e-na le hoo.
A-terminal (1310nm / 1550nm) le B-terminal (1550nm / 1310nm) e hlahile.
Basebelisi ba tlameha ho sebelisa marang-rang a AB, eseng khokahano ea AA kapa BB.
Qetello ea AB e sebelisoa feela bakeng sa li-transceivers tse le 'ngoe tsa fiber optic.
2.Dual fiber transceiver
Transceiver e nang le fiber tse peli e na le boema-kepe ba TX (boema-kepe bo fetisang) le boema-kepe ba RX (boema-kepe bo amohelang). Boema-kepe ka bobeli bo fetisa ka bolelele bo lekanang ba 1310nm, 'me kamohelo e boetse e le 1310nm. Ka hona, likhoele tse peli tse tšoanang tsa optical tse sebelisoang ha ho etsoa wiring li hokahane.
3. U ka khetholla joang transceiver ea fiber e le 'ngoe ho tloha ho tse peli tsa fiber transceiver?
Hona joale ho na le litsela tse peli tsa ho khetholla li-transceivers tsa fiber e le 'ngoe ho li-transceivers tse peli tsa fiber.
① Ha transceiver ea optical e kenngoa ka mochine oa optical, transceiver ea optical e arotsoe ka transceiver e le 'ngoe ea fiber le transceiver ea li-fiber tse peli ho ea ka palo ea li-cores tsa jumper e kopantsoeng ea optical fiber. Tsela ea "optical fiber jumper" e kopantsoeng le transceiver ea fiber e le 'ngoe (ka ho le letona) ke fiber core, e ikarabellang bakeng sa ho fetisetsa le ho amohela data; Linearity ke li-cores tse peli. E 'ngoe ea mantlha e na le boikarabello ba ho fetisa data 'me e 'ngoe ea mantlha e ikarabella ho amohela data.
②Ha transceiver ea optical fiber e se na mochine oa optical o kenngoeng, ho hlokahala hore u khetholle pakeng tsa transceiver e le 'ngoe ea fiber le transceiver ea fiber e peli ho ea ka mochine oa optical o kentsoeng. Ha mochine o le mong oa fiber bidirectional optical o kenngoa ho optical fiber transceiver, ke hore, sebopeho ke mofuta o bonolo, optical fiber transceiver ke transceiver e le 'ngoe ea fiber (setšoantšo se nepahetseng); ha mochine o nang le li-fiber bidirectional optical module o kenngoa ka har'a optical fiber transceiver, Ke hore, ha sebopeho se le mofuta oa duplex, transceiver ena ke transceiver ea li-fiber tse peli (setšoantšo se letšehali).
