Coarse Wavelength Division Multiplexing (CWDM) ke ts'ebeliso ea Fibre Optical Multiplexer ho li-wavelength tse fapaneng tsa lipontšo tsa khanya tse atolositsoeng ho fiber e le 'ngoe ea khanya bakeng sa phetiso, qetellong ea khokahano, ka Fiber Optical Multiplexer fiber e tsoakiloeng e aroloa ka ho fapana. matšoao a maqhubu, a hokahantsoeng le lisebelisoa tse hlokahalang.
100GHz CWDM Mux / Demux Module ka holim'a fiber e le 'ngoe kapa duplex single mode e tloaelehile haholo ho atolosa bandwidth ea hau ka kakaretso. E fana ka botsitso bo phahameng le ts'epahalo, mme e na le boholo bo fokolang ba sephutheloana. Wavelength ea eona e sebetsang e tsoa ho 1270nm ho isa 1610nm (1261nm-1611nm) e fanang ka liteishene tse 18 ka ho hlaka sebaka sa 20nm.
