Ka bobeli fiber e le 'ngoe le tse peli tsa fiber optical modules li ka fetisa le ho amohela.Kaha lipuisano tse peli li tlameha ho khona ho fetisa le ho amohela.Phapang ke hore mochini o le mong oa fiber optical o na le kou e le 'ngoe feela.Theknoloji ea Wavelength division multiplexing (WDM) e sebelisetsoa ho kopanya mefuta e fapaneng ea ho amohela le ho fetisetsa maqhubu ka har'a fiber e le 'ngoe, ho sefa ka sefahla ka mochine oa optical,' me ka nako e le 'ngoe ho phethe phetisetso ea matšoao a 1310nm le ho amoheloa ha matšoao a 1550nm, kapa ka tsela e fapaneng. .Ka hona, mojule o tlameha ho sebelisoa ka bobeli (ho ke ke ha khoneha ho khetholla fiber e nang le leqhubu le tšoanang la transceiver wavelength).
Ka hona, mochine o le mong oa fiber optical o na le sesebelisoa sa WDM, 'me theko e phahame ho feta ea dual fiber optical module.Kaha li-modules tse peli tsa fiber optical li amohela le ho amohela likoung tse fapaneng tsa optical fiber, ha li kena-kenane, ka hona ha li hloke WDM, kahoo maqhubu a maqhubu a ka tšoana.Theko e theko e tlase ho feta ea fiber e le 'ngoe, empa e hloka lisebelisoa tse ngata tsa fiber.
Double fiber optical module le single fiber optical module ha e le hantle li na le phello e ts'oanang, phapang feela ke hore bareki ba ka khetha fiber e le 'ngoe kapa fiber e habeli ho latela litlhoko tsa bona.
Single fiber optical module e theko e boima haholo, empa e ka boloka mohloli oa fiber, e leng khetho e molemo ho basebelisi ba nang le lisebelisoa tse sa lekaneng tsa fiber.
Dual fiber optical module e batla e le theko e tlase, empa e hloka ho sebelisa fiber e le 'ngoe hape.Haeba lisebelisoa tsa fiber li lekane, o ka khetha dual fiber optical module.
