Optical modules ndi optical fiber transceivers ndi zipangizo zomwe zimapanga photoelectric conversion. Kodi pali kusiyana kotani pakati pawo? Masiku ano, kutumiza kwa data mtunda wautali komwe kumagwiritsidwa ntchito m'mapulojekiti ambiri anzeru makamaka kumagwiritsa ntchito ma fiber optical transmission. Kulumikizana pakati pa izi kumafuna ma module optical ndi ma transceivers a fiber optic. Kotero, kodi ziwirizi ziyenera kugwirizana bwanji, ndipo ndi chiyani chomwe chiyenera kutsatiridwa?
1. Optical module
Ntchito ya optical module ndiyonso kutembenuka pakati pa zizindikiro za photoelectric. Amagwiritsidwa ntchito kwambiri chonyamulira pakati pakusinthandi chipangizo. Lili ndi mfundo yofanana ndi optical fiber transceiver, koma optical module ndi yothandiza komanso yotetezeka kuposa transceiver. Ma module a kuwala amagawidwa molingana ndi mawonekedwe a phukusi. Zodziwika bwino ndi SFP, SFP +, XFP, SFP28, QSFP +, QSFP28, etc.
2. Transceiver ya kuwala kwa fiber
Optical fiber transceiver ndi chipangizo chomwe chimasintha ma siginecha amagetsi akutali komanso ma sign atali atali. Nthawi zambiri amagwiritsidwa ntchito potumiza mtunda wautali, kutumiza kudzera mu ulusi wa optical, kutembenuza zizindikiro zamagetsi kukhala zizindikiro za kuwala ndikuzitumiza. Chizindikiro cholandira kuwala chimasinthidwa kukhala chizindikiro chamagetsi. Imatchedwanso Fiber Converter m'malo ambiri.
Ma transceivers a Fiber optic amapereka njira yotsika mtengo kwa ogwiritsa ntchito omwe amafunikira kukweza dongosolo kuchokera ku waya wamkuwa kupita ku fiber optics, koma alibe ndalama, antchito kapena nthawi.
3. Kusiyana pakati pa optical module ndi optical fiber transceiver
① Yogwira komanso yongokhala: Optical module ndi gawo logwira ntchito, kapena chowonjezera, ndi chipangizo chomwe sichingagwiritsidwe ntchito chokha, ndipo chimangogwiritsidwa ntchitomasiwichindi zida zokhala ndi mipata ya optical module; optical fiber transceivers ndi zida zogwirira ntchito. Ndi chipangizo chapadera chogwira ntchito, chomwe chitha kugwiritsidwa ntchito chokha chikalumikizidwa;
②Kupititsa patsogolo kasinthidwe: Module ya kuwala imathandizira kusinthana kotentha, kasinthidwe kake kamakhala kosavuta; optical fiber transceiver ndi yokhazikika, ndipo m'malo mwake ndikukweza kumakhala kovuta kwambiri;
③Mtengo: Ma transceivers opangira ma fiber owoneka bwino ndi otsika mtengo kuposa ma module owoneka bwino ndipo ndi otsika mtengo komanso ogwira ntchito, komanso amayenera kuganizira zinthu zambiri monga adaputala yamagetsi, mawonekedwe a kuwala, mawonekedwe a chingwe cha netiweki, ndi zina zambiri, ndipo kutayika kwa kutayika kumatenga pafupifupi 30%;
④ Ntchito: Ma module a Optical amagwiritsidwa ntchito kwambiri pazida zoyankhulirana za netiweki, monga mawonekedwe ophatikizika.masiwichi, kambama routers, DSLAM,OLTndi zipangizo zina, monga: kompyuta kanema, deta kulankhulana, opanda zingwe kulankhulana mawu ndi zina kuwala CHIKWANGWANI network msana; Optical fiber transceiver Imagwiritsidwa ntchito pamalo enieni amtaneti pomwe chingwe cha Efaneti sichingathe kuphimba ndipo chimayenera kugwiritsa ntchito ulusi wowoneka bwino kuti chiwonjezeke mtunda wotumizira, ndipo nthawi zambiri chimayikidwa ngati njira yolumikizira maukonde amtundu wa Broadband Metropolitan Area;
4. Ndi chiyani chomwe chiyenera kutsatiridwa pamene mukugwirizanitsa optical module ndi optical fiber transceiver?
① Liwiro la module ya optical ndi transceiver ya fiber optical iyenera kukhala yofanana, 100 megabytes mpaka 100 megabytes, gigabit mpaka gigabit, ndi 10 megabytes mpaka 10 thililiyoni.
② Kutalika kwa mafunde ndi kufalikira kuyenera kukhala kofanana, mwachitsanzo, kutalika kwa mafunde ndi 1310nm kapena 850nm nthawi yomweyo, ndipo mtunda wotumizira ndi 10km;
③ Mtundu wa kuwala uyenera kukhala wofanana, ulusi umodzi mpaka ulusi umodzi, ulusi wapawiri mpaka wapawiri.
④ Majumpha a ulusi kapena ma pigtails ayenera kulumikizidwa kudzera mu mawonekedwe omwewo. Nthawi zambiri, ma transceivers a fiber optic amagwiritsa ntchito ma doko a SC ndipo ma module opangira amagwiritsa ntchito madoko a LC.
