2. Transceiver ea fiber e ka fetoloa pakeng tsa 10M, 100M, kapa 1000M Ethernet interface ea motlakase le sebopeho sa optical.
3, ho sebelisa transceiver ea optical fiber ho haha marang-rang ho ka boloka matsete a marang-rang.
4. Fiber optic transceiver e etsa hore khokahanyo pakeng tsa seva, pheta-pheta, hub, terminal le terminal e atlehe haholoanyane.
5, fiber transceiver e na le microprocessor le segokanyimmediamentsi sa sebolokigolo, e ka fana ka lintlha tse fapaneng tsa ts'ebetso ea lihokelo tsa data.
2. Ke efe e hlahisang kapa e amohelang transceiver ea fiber-optic?
Ha u sebelisa transceiver ea fiber ea optical, metsoalle e mengata e tla kopana le potso e joalo:
1. Na transceiver ea optic fiber optic e tlameha ho sebelisoa ka bobeli?
2, optical fiber transceiver ha e na lintlha, motho o lokela ho e amohela ke ho romela? Kapa na li-transceiver tse peli tsa fiber li ka sebelisoa e le para?
3. Haeba transceiver ea fiber ea optical e tlameha ho sebelisoa ka bobeli, na para e lokela ho tšoana le mofuta o tšoanang? Kapa na u ka sebelisa motsoako ofe kapa ofe oa mofuta ofe kapa ofe?
Metsoalle e mengata e ka ba le potso ena ts'ebetsong ea ts'ebeliso ea morero, joale ke eng? Karabo: optical fiber transceiver e le lisebelisoa tsa ho fetola photoelectric hangata li sebelisoa ka bobeli, empa hape li ka hlaha transceiver ea optical fiber le optical fiber transceiver, optical fiber transceiver le SFP transceiver pairing tshebediso le tsona ke tse tlwaelehileng, ha e le hantle, ha feela optical transceiver optical wavelength e ntse e le teng. e ts'oanang, sebopeho sa encapsulation se ts'oana mme se ts'ehetsa protocol e 'ngoe e ka hlokomela puisano ea optical fiber. Kakaretso ea single mode double fiber (puisano e tloaelehileng e hloka li-fiber tse peli) transceiver ho sa tsotellehe hore na transmitter le qetello ea ho amohela, ha feela para e ka sebelisoa. Ke feela fiber e le 'ngoe ea transceiver (puisano e tloaelehileng e hloka fiber) e tla ba le pheletso e fapaneng ea phetisetso le pheletso e amohelang.
Ebang ke transceiver ea fiber e habeli kapa transceiver e le 'ngoe ea fiber e lokela ho sebelisoa ka bobeli, mefuta e fapaneng e ka lumellana le tšebelisano. Empa lebelo, wavelength, le paterone lia tšoana. Ka mantsoe a mang, litekanyetso tse fapaneng (100 le gigabit), li-wavelengths tse fapaneng (1310nm le 1300nm) ha li khone ho buisana, ho phaella moo, esita le mofuta o le mong oa fiber transceiver le mefuta e 'meli ea fiber para ha e kopane. Kahoo potso ke hore, transceiver ea fiber e le 'ngoe ke eng, hona transceiver ea fiber e habeli ke eng? Phapano ke efe pakeng tsa bona?
3. Transceiver ea fiber e le 'ngoe ke eng? Transceiver ea fiber e habeli ke eng?
Single fiber transceiver e bua ka tšebeliso ea thapo ea optical ea mofuta o le mong, fiber e le 'ngoe ea transceiver ke motheo feela, lipheletsong ka bobeli li hokahane le mantlha, lipheletsong tse peli tsa transceiver li sebelisa li-wavelengths tse fapaneng tsa khanya, kahoo e ka fetisa pontšo ea leseli bohareng. Double fiber transceiver ke tšebeliso ea li-cores tse peli, ho romelloa ho amohela, pheletso e 'ngoe ke moriri, pheletso e' ngoe e tlameha ho kenngoa koung, ke lipheletso tse peli ho tšela.
1, transceiver ea fiber e le 'ngoe
Transceiver e le 'ngoe ea fiber e lokela ho hlokomela bobeli mosebetsi oa ho fetisa le oa ho amohela. E sebelisa theknoloji ea "wave division multiplexing" ho fetisetsa lipontšo tse peli tsa optical tsa wavelengths tse fapaneng ka har'a fiber ea optical ho hlokomela phetisetso le kamohelo.
Kahoo transceiver e le 'ngoe ea fiber e fetisoa ka fiber, kahoo leseli le fetisang le ho amohela le fetisoa ka fiber core ka nako e le' ngoe. Tabeng ena, maqhubu a mabeli a khanya a tlameha ho sebelisoa ho finyella puisano e tloaelehileng.
Ka hona, mochine oa optical oa single-mode single-fiber transceivers o na le maqhubu a mabeli a optical wavelengths, ka kakaretso 1310nm / 1550nm, kahoo li-terminals tse peli tsa li-transceivers li tla fapana. Transceiver ea pheletso e le 'ngoe e fetisa 1310nm mme e amohela 1550nm. Ka lehlakoreng le leng, e hlahisa 1550nm mme e amohela 1310nm. Ho loketse hore basebelisi ba khetholle, hangata ba tla sebelisa litlhaku ho fapana le hoo. Qetello A (1310nm / 1550nm) le qetello ea B (1550nm / 1310nm) e hlahile. Basebelisi ba tlameha ho kopanngoa ka AB ho e sebelisa, eseng khokahano ea AA kapa BB. AB e sebelisoa feela ke transceiver ea fiber e le 'ngoe.
2, transceiver ea fiber e habeli
Transceiver ea fiber e habeli e na le boema-kepe ba TX (boema-kepe bo fetisang) le boema-kepe ba RX (boema-kepe bo amohelang). Likou tsena ka bobeli li na le bolelele bo lekanang ba 1310nm, 'me kamohelo ke 1310nm, kahoo likhoele tse peli tse tšoanang tsa optical li sebelisoa bakeng sa khokahano ea sefapano.
3, mokhoa oa ho khetholla transceiver ea fiber e le 'ngoe le transceiver ea fiber e habeli
Ho na le litsela tse peli tsa ho khetholla li-transceivers tsa fiber tse le 'ngoe ho tloha ho li-transceivers tse peli tsa fiber.
① Ha transceiver ea optical fiber e kenngoa ka mochine oa optical, transceiver ea optical fiber e arotsoe ka fiber e le 'ngoe le transceiver ea fiber e habeli ho ea ka palo ea li-jumper cores tse kopantsoeng. Transceiver ea fiber e le 'ngoe (ka ho le letona) e hokahane le fiber core, e ikarabellang bakeng sa ho fetisa data le ho amohela data, ha transceiver ea fiber e habeli (ka ho le letšehali) e hokahane le li-fiber cores tse peli, e 'ngoe ea tsona e ikarabellang bakeng sa ho fetisa data le e 'ngoe e na le boikarabello ba ho amohela data.
② Ha transceiver ea optical fiber e se na module ea optical e kenngoeng, hoa hlokahala ho khetholla hore na transceiver e le 'ngoe ea fiber kapa transceiver ea fiber e peli ho ea ka mochine oa optical o kentsoeng. Ha transceiver ea optical fiber e kenngoa ka mochine o le mong oa fiber bidirectional optical module, ke hore, sebopeho ke mofuta o le mong, fiber transceiver ena (ka ho le letona); ha fiber transceiver e kenngoa ka double fiber bidirectional optical module, kapa sebopeho ke mofuta oa duplex, transceiver ke double fiber transceiver (setšoantšo se letšehali).
