Ma fiber optic transceivers nthawi zambiri amagwiritsidwa ntchito pamalo enieni amtaneti pomwe zingwe za Efaneti sizingathe kubisala ndipo zimayenera kugwiritsa ntchito ulusi wa kuwala kuti atalikitse mtunda wotumizira. Nthawi zambiri amakhala pamalo ofikira ma network a Broadband metropolitan area, ndipo amagwiritsidwa ntchito kwambiri m'malo osiyanasiyana ...

Optical access network ndi njira yofikira yomwe imagwiritsa ntchito kuwala ngati njira yotumizira, kulowetsa mawaya amkuwa, ndipo imagwiritsidwa ntchito kuti ifike kunyumba iliyonse. Netiweki yolumikizira nthawi zambiri imakhala ndi magawo atatu: optical line terminal OLT, optical network unit ONU, ndi neti yogawa ...

Kawirikawiri, mphamvu yowala ya optical fiber transceiver kapena optical module ili motere: multimode ili pakati pa 10db ndi -18db; single mode ndi 20km pakati -8db ndi -15db; ndi mode limodzi ndi 60km ali pakati -5db ndi -12db pakati. Koma ngati mphamvu yowala ya pulogalamu ya fiber optic transceiver ...

Liwiro la optical module SFP + ndi: 10G SFP + optical transceiver ndikukweza kwa SFP (nthawi zina amatchedwa "mini-GBIC"). SFP yakhala ikugwiritsidwa ntchito kwambiri pa Gigabit Ethernet ndi 1G, 2G, ndi 4G Fiber Channel. Kuti zigwirizane ndi kuchuluka kwa data, SFP+ yapanga ma elekitiromu owonjezera ...

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 kutumiza kwa fiber. Kulumikizana pakati pa izi kumafuna mawonekedwe owoneka ...

Malingana ndi kuyesera, Gigabit SFP optical module ikhoza kugwira ntchito pa 10 Gigabit SFP + doko, koma 10 Gigabit SFP + optical module sangathe kugwira ntchito pa doko la Gigabit SFP. Pamene Gigabit SFP optical module ilowetsedwa mu 10 Gigabit SFP + doko, liwiro la doko ili ndi 1G, osati 10G ....
