Fiber optic modemli boetse li bitsoa fiber optic modem.Mosebetsi oa eona o ka sehloohong ke ho etsa phetoho ea matšoao.Ke sesebelisoa sa relay se sebelisetsoang phetiso ea marang-rang."Fiber optic modem" hangata e sebelisoa bakeng sa sebaka sa phetisetso se fetang 20KM le lebelo le fetang 2M.Lisebelisoa tsa phetisetso ea mahlo tse kang SDH / PDH lia hlokahala bohareng.Tabeng ea phetisetso, ho sebelisoa modem ea optical, eo haholo-holo e kenngoa lipheletsong tse peli tsa optical fiber mme e fetola data e fetisitsoeng pakeng tsa matšoao a motlakase le matšoao a optical.Ha optical broadband e kenngoa ka tlung, li-modem tsa optical li sebelisoa ho fetola matšoao e le hore lik'homphieutha le lisebelisoa tse ling li ka lemoha matšoao ana.Hona joale li-modem tsa optical li hokahanya lifono, lithelevishene, li-broadband, li-routers le phihlello ea inthanete e se nang mohala.
2.Optical fiber transceiver
Transceiver ea fiber ea opticke mofuta oa thepa ea ho fetola photoelectric e fapanyetsanang sebaka se sekhuts'oane sa mats'oao a motlakase a sothehileng le mats'oao a mahlo a malelele.Letšoao la optical le kenngoa ho tloha ho optical port mme letšoao la motlakase le hlahisoa ho tloha koung ea motlakase (RJ45 crystal head interface).Ts'ebetso ke ho fetolela matšoao a motlakase hore e be matšoao a optical le ho a fetisa ka likhoele tsa optical.Ka lehlakoreng le leng, lipontšo tsa optical li fetoloa lipontšo tsa motlakase, ebe li kopantsoe ho li-routers, li-switches le lisebelisoa tse ling.
Ho ea ka sebaka sa phetisetso, li ka aroloa ka li-transceivers tsa mode e le 'ngoe le li-multi-mode.① Transceiver optical fiber ea mofuta o le mong: sebaka sa phetisetso se pakeng tsa lik'hilomithara tse 20 ho isa ho tse 120;②Multi-mode optical fiber transceiver: sebaka sa phetisetso se pakeng tsa 2 kilometers le 5 kilometers.
Ts'ebetsong ea phetisetso, li-transceivers tsa fiber optic li tlameha ho sebelisoa ka bobeli, tse loketseng sebaka se hole ho feta limithara tse 100, leseli le leng le le leng le bonts'a moelelo o fapaneng, 1000-ha le bulehile, le emela sekhahla sa 1000M, 100-ha se bulehile, se emela. 100M sekhahla;FX- Ha e sebetsa, e bolela hore pigtail e hokahane, 'me ha e benya, e bolela hore data e ntse e fetisoa;FX LINK/ACT-ha e bulehile, e bolela hore thapo ea marang-rang e hokahane, le ha e a benya, ho bolela hore data e ntse e fetisoa;ha e bulehile, ho bolela hore thapo ea matla e hokahane;TX LINK/ACT— -Ha e bulehile, e emela sekhahla se felletseng sa duplex, 'me ha e tima, e emela halofo ea duplex.
