Thefiber optic transceiveriEthernet transmission media conversion unit iyo inotsinhanisa masaini mapfupi-akamonyoroka-peya masaini emagetsi uye masaini akareba-akareba.Inonziwo photoelectric converter munzvimbo dzakawanda.Chigadzirwa chacho chinowanzoshandiswa munharaunda chaiyo yetiweki apo Ethernet cable haigoni kuvhara uye fiber optical inofanira kushandiswa kuwedzera nzvimbo yekufambisa, uye inowanzoiswa muchikamu chekuwana. iyo optical fiber Broadband metropolitan area network;panguva imwechete, inobatsira kubatanidza maira ekupedzisira e-optical fiber kuguta.Nharaunda yenharaunda uye network yekunze yakaitawo basa guru.
Zvichitaurwa zviri nyore, basa refiber optic transceiver ndiko kutendeuka kwakabatana pakati pezviratidzo zvemaziso uye masaini emagetsi.Chiratidzo chemaziso chinowanikwa kubva kune optical port, uye chiratidzo chemagetsi chinobuda kubva kumagetsi emagetsi (yakajairika RJ45 crystal head interface), uye zvakasiyana-siyana.Iyo nzira inenge iine: kushandura zviratidzo zvemagetsi mumagetsi emagetsi, achivatumira kuburikidza ne optical fibers, uye wozoshandura zviratidzo zvemaziso kuita zviratidzo zvemagetsi kune imwe mugumo, uye wozozvibatanidza kune ma routers, switch uye zvimwe midziyo.
Ndezvipi zvikamu zve fiber optic transceivers
Makona akasiyana ekuona anoita kuti vanhu vave nekunzwisisa kwakasiyana kwefiber optic transceivers:
Semuenzaniso, maererano nehuwandu hwekufambisa, yakakamurwa kuva imwechete 10M, 100M fiber optic transceivers,10/100M inogadzirisa fiber optic transceiversuye 1000M fiber optic transceivers;
Maererano nemaitiro ekushanda, yakakamurwa kuva fiber optic transceivers inoshanda pamucheka wenyama uye fiber optic transceivers inoshanda pa data link layer;
Kubva pakuona kwemaitiro, yakakamurwa kuva desktop (yakamira-yega) fiber optic transceivers uye rack-mounted fiber optic transceivers;
Zvinoenderana neakasiyana mafibhi ekuwana, kune mazita maviri: multi-mode fiber transceiver uye single-mode fiber transceiver.
Mukuwedzera, kune imwe-fiber fiber optic transceivers uyemaviri-fiber fiber optic transceivers, yakavakirwa-musimba refiber optic transceivers uye kunze kwesimba fiber optic transceivers, pamwe chete neanotarisirwa fiber optic transceivers uye isina kutarisirwa fiber optic transceivers.
Fiber optic transceivers inotyora iyo 100-mita yekugumira yeEthernet tambo mukufambiswa kwedata, ichivimba nepamusoro-inoshanda switching machipisi uye yakakura-inotakura buffers, nepo ichinyatso zadzisa isingavharise kutapurirana uye kushandura mashandiro, inopawo yakaenzana traffic, kuparadzaniswa kwemakakatanwa uye. Kuonekwa kwekukanganisa uye mamwe mabasa anovimbisa kuchengetedzwa kwepamusoro uye kugadzikana panguva yekufambisa data.
Ndekupi kushandiswa kwemhando ye fiber optic transceivers
Muchidimbu, iyo optical fiber transceiver inongopedzisa kutendeuka kwedata pakati pemidhiya yakasiyana-siyana, iyo inogona kuona kuwirirana pakati pemagetsi maviri kana makombiyuta mukati me 0-120Km, asi kushandiswa kwechokwadi kune kuwedzera kwekuwedzera.
- Ziva kubatana pakatiswitches.
- Ziva kubatana pakati pekuchinja uye komputa.
- Ziva kubatana pakati pemakomputa.
- Transmission relay: Kana iyo chaiyo yekufambisa nhanho inodarika zita rekutumira kureba kweiyo transceiver, kunyanya kana iyo chaiyo yekufambisa kureba ichipfuura 120Km, kana nzvimbo yenzvimbo ichibvumidza, shandisa 2 transceivers yekudzoka-kumashure relay kana chiedza-ku-optical kutendeuka. relay ndiyo inodhura-inoshanda mhinduro.
- Single-multi-mode kutendeuka: Kana imwe-multi-mode fiber connection inodiwa pakati pemambure, imwe-multi-mode converter inogona kushandiswa kubatanidza, iyo inogadzirisa dambudziko re single-multi-mode fiber conversion.
- Wavelength division multiplexing transmission: Kana kureba-kure optical fiber cable zviwanikwa zvisingakwanisi, kuitira kuti uwedzere kushandiswa kwetambo ye optical uye kuderedza mutengo, transceiver uye wavelength division multiplexer inogona kushandiswa pamwe chete kuendesa nzira mbiri dze. ruzivo rwepairi imwechete ye optical fibers.
