Optical module ke mofuta oa lisebelisoa tsa khokahano ea marang-rang ho elelloa phetoho ea lets'oao la photoelectric, 'me transponder ke mofuta oa lisebelisoa tsa khokahano ea marang-rang ho hlokomela ntlafatso ea optical signal regenerative le wavelength conversion. Le hoja mochine oa optical le transponder ka bobeli ba itšetlehile ka molao-motheo oa phetoho ea photoelectric 'me ba ka hlokomela phetoho ea photoelectric, empa mosebetsi le kopo li fapane,' me li ke ke tsa nka sebaka sa tse ling. Sehlooho sena se tla u bolella phapang pakeng tsa optical modules le converters ka botlalo haholo.
E le lisebelisoa tsa puisano bakeng sa ho fetisa le ho amohela matšoao a optical, mochine oa optical o atisa ho sebelisoa mekhoeng ea puisano ea optical fiber e kang setsi sa data, marang-rang a khoebo, cloud computing, le FTTX. Hangata, li-module tsa optical li tšehetsa phetoho e chesang, e ka sebelisoang mocheng oa li-switches tsa marang-rang, li-server le lisebelisoa tse ling tsa marang-rang. Hona joale, ho na le mefuta e mengata ea optical modules 'marakeng, e kang 1G SFP, 10 GSFP +, 25G SFP 28,40G QSFP +, 100G QSFP, 28,400G QSFP-DD optical modules, joalo-joalo Hangata li sebelisoa ka mefuta e sa tšoaneng ea optical fiber jumpers kapa likhoele tsa marang-rang ho hlokomela phetiso ea marang-rang libakeng tse fapaneng, ho tloha ho 30km ho isa ho 160km. Ho phaella moo, BiDi optical module e ka fetisetsa le ho amohela lipontšo ka fiber e le 'ngoe ea optical, ka katleho ho nolofatsa mohala, ho ntlafatsa bokhoni ba marang-rang, le ho fokotsa litšenyehelo tsa lisebelisoa tsa cabling. Ka mokhoa o ts'oanang, li-module tsa optical tsa WDM series (ke hore, CWDM le DWDM optical modules) li ka boela tsa sebelisa matšoao a mefuta e sa tšoaneng ea maqhubu ho ea ho optical fiber e tšoanang, e atisang ho bonoa ho marang-rang a WDM / OTN.
Transponder, eo hape e tsejoang e le photoelectric wavelength converter kapa optical amplifier repeater, ke optical fiber media converter e kopanyang transmitter le receiver. E ka atolosa sebaka sa phetisetso ea marang-rang ka ho fetola wavelength le ho hōlisa matla a optical, 'me e na le mosebetsi oa ho matlafatsa ho leka-lekana, ho ntša nako le ho lemoha lipontšo tse nchafalitsoeng tsa optical.Mehleng ena, li-transponders tse tloaelehileng' marakeng ke 10G / 25G / 100G, Har'a tsona, 10G / 25G e pheta-phetoang e ka lemoha phetoho ea fiber ea optical (joalo ka phetoho ea fiber e le 'ngoe ho ea ho single-fiber bi-directional), phetoho ea mofuta oa fiber (multi-mode optical fiber ho fiber optical mode e le' ngoe) le ntlafatso ea lets'oao la optical (ka ho fetola lets'oao le tloaelehileng la wavelength optical ho latela tlhaloso ea ITU-T wavelength ho fihlela ntlafatso ea amplification, sebopeho le ho lokisa nako hape; Hangata e sebelisoa hammoho le EDFA fiber optic amplifier le DCM dispersion compensator, E sebelisoa haholo ho MAN, marang-rang a WDM, Haholo-holo ho marang-rang a DWDM a nako e telele. 100G repeater (ke hore 100G multiplexing repeater) e hlahisoa haholo-holo bakeng sa phetisetso ea 10G / 40G / 100G ho fetola li-interfaces tse fapaneng tsa optical ka mokhoa o bonolo. Ka mantsoe a mang, 100G repeater e ka tšehetsa motsoako o feto-fetohang oa 10 GbE, 40 GbE le 100 GbE, 'me e ka sebelisoa marang-rang a khoebo, marang-rang a marang-rang, khokahano e kholo ea setsi sa data, MAN le lisebelisoa tse ling tse hōle.
Ho tsoa ka holimo, module ea optical le e pheta-pheta e ka fetola matšoao a motlakase hore e be matšoao a optical, empa phapang pakeng tsa tse peli ke:
1. Optical module ke serial interface, fetisetsa le ho amohela lipontšo ka hare ho optical module, ha repeater e le sebopeho se ts'oanang 'me e tlameha ho bapisa mochine oa optical ho hlokomela phetiso ea matšoao. Optical module, lehlakore le leng le sebelisetsoa ho fetisa matšoao 'me lehlakore le leng le sebelisetsoa ho amohela lipontšo.
2. Le hoja mochine oa optical o ka lemoha phetoho ea photoelectric, transponder e ka fetola lipontšo tsa photoelectric ho tloha ho mefuta e sa tšoaneng ea maqhubu.
3. Le hoja converter e ka boela ea sebetsana habonolo le matšoao a tlaase a bapisoang, e na le boholo bo boholo le matla a phahameng a sebelisoang ha a bapisoa le optical module.
Ka bokhutšoanyane, transponder e ka bonoa e le mochine oa optical o qhaqhoa, o phethela phetisetso ea marang-rang ea WDM e hōle eo mochine oa optical o ke keng oa khona.
