Optical module ndi mtundu wa zida zolumikizira netiweki kuti zizindikire kutembenuka kwa chithunzi chamagetsi, ndipo transponder ndi mtundu wa zida zolumikizira maukonde kuti zizindikire kukulitsa kwamphamvu kwamagetsi ndi kutembenuka kwakutali. Ngakhale gawo kuwala ndi transponder onse zochokera photoelectric kutembenuka mfundo ndipo akhoza kuzindikira photoelectric kutembenuka, koma ntchito ndi ntchito ndi zosiyana, ndipo sangathe m'malo wina ndi mzake. Nkhaniyi ikuuzani kusiyana pakati pa ma module a kuwala ndi otembenuza mwatsatanetsatane.
Monga zida zoyankhulirana zotumizira ndi kulandira ma sign optical, optical module nthawi zambiri amagwiritsidwa ntchito pamakina olumikizirana optical fiber monga data center, network network, cloud computing, ndi FTTX. Nthawi zambiri, ma module owoneka amathandizira kusinthana kotentha, komwe kungagwiritsidwe ntchito pagawo la ma switch network, ma seva ndi zida zina zamaukonde. Pakali pano, pali mitundu yambiri ya ma modules optical pamsika, monga 1G SFP, 10 GSFP +, 25G SFP 28,40G QSFP +, 100G QSFP, 28,400G QSFP-DD optical modules, ndi zina zotero. optical CHIKWANGWANI jumpers kapena zingwe maukonde kuzindikira kufala maukonde pa mtunda osiyana, kuyambira 30km kuti 160km. Kuphatikiza apo, BiDi Optical module imatha kutumiza ndikulandila zidziwitso kudzera mumtundu umodzi wamagetsi, kufewetsa mawaya, kuwongolera mphamvu ya netiweki, ndikuchepetsa mtengo wamagetsi opangira ma cabling. Mofananamo, WDM series optical modules (ie, CWDM ndi DWDM optical modules) angagwiritsenso ntchito zizindikiro za kutalika kwa mawonekedwe a kuwala komweko, komwe kumawoneka mu WDM / OTN network.
Transponder, yomwe imadziwikanso kuti photoelectric wavelength converter kapena optical amplifier repeater, ndi optical fiber media converter kuphatikiza transmitter ndi wolandila. Ikhoza kukulitsa mtunda wa kufala kwa maukonde mwa kutembenuza kutalika kwa kutalika ndi kukulitsa mphamvu ya kuwala, ndipo imakhala ndi ntchito yokulitsa bwino, kuchotsa nthawi ndi kuzindikira zizindikiro za kuwala zosinthidwa. 10G / 25G wobwereza amatha kuzindikira kutembenuka kwa fiber fiber (monga kutembenuka kwa fiber iwiri njira imodzi kukhala imodzi-fiber bi-directional), kutembenuka kwamtundu wa fiber (multi-mode optical fiber kukhala single-mode optical fiber) ndi kukweza chizindikiro cha kuwala (potembenuza Wavelength kuwala chizindikiro molingana ndi tanthauzo la ITU-T wavelength kukwaniritsa kukulitsa kusinthika, mawonekedwe ndi kukonzanso nthawi ya wotchi); Nthawi zambiri amagwiritsidwa ntchito limodzi ndi EDFA fiber optic amplifier ndi DCM dispersion compensator, Amagwiritsidwa ntchito kwambiri mu MAN, WDM networks, Makamaka muutali wautali wautali wa DWDM maukonde. The 100G repeater (ie 100G multiplexing repeater) makamaka imapangidwira kufalitsa kwa 10G / 40G / 100G kuti atembenuzire mawonekedwe osiyanasiyana owoneka bwino. Izi zikutanthauza kuti, 100G repeater ikhoza kuthandizira kusinthasintha kwa 10 GbE, 40 GbE ndi 100 GbE, ndipo ingagwiritsidwe ntchito pa intaneti yamalonda, malo osungiramo malo, kugwirizanitsa kwakukulu pakati pa data, MAN ndi mapulogalamu ena akutali.
Kuchokera pamwambapa, module ya kuwala ndi yobwereza imatha kusintha ma siginecha amagetsi kukhala ma siginecha owoneka, koma kusiyana pakati paziwiri ndi:
1. Optical module ndi mawonekedwe a serial, kutumiza ndi kulandira zizindikiro mkati mwa optical module, pamene obwerezabwereza ndi mawonekedwe ofanana ndipo ayenera kufanana ndi mawonekedwe a kuwala kuti azindikire kutumiza kwa chizindikiro. Optical module, mbali imodzi imagwiritsidwa ntchito potumiza zizindikiro ndipo mbali inayo imagwiritsidwa ntchito kulandira zizindikiro.
2. Ngakhale kuti module ya kuwala imatha kuzindikira kutembenuka kwa photoelectric, transponder ikhoza kutembenuza zizindikiro za photoelectric kuchokera kumtunda wosiyanasiyana.
3. Ngakhale kuti chosinthiracho chimatha kugwiranso mosavuta zizindikiro zofananira zotsika, zimakhala ndi kukula kwakukulu komanso kugwiritsa ntchito mphamvu zambiri poyerekeza ndi optical module.
Mwachidule, transponder imatha kuwonedwa ngati gawo la optical disassembled, limamaliza kufalitsa kwakutali kwa WDM network yomwe mawonekedwe owoneka sangathe.
Shenzhen HDV Phoelectron Technology Ltd. yopanga mwapadera opanga ma module a kuwala. Osati kokhaONUmndandanda,OLTmndandanda,kusinthamndandanda, mitundu yonse ya ma modules ilipo, Iwo omwe akufunika kuyendera ndi kudziwa zambiri amalandiridwa.
