IINKCUKACHA ZEMVELISO

Ingcaciso yeMveliso

I-CWDM-55 yi-1550nm CWDM mux okanye isixhobo se-demux esakhelwe ngaphakathi i-1550nm isihluzi esongeza isignali ye-1550nm kwi-port ye-com okanye iwisa isignali ye-1550nm ukusuka kwi-com port. Isixhobo se-CWDM-xx sechungechunge sikulungele ukongeza okanye ukulahla i-xx CWDM channel kwi-fiber optic system. Ubude obuqhelekileyo be-CWDM ukusuka kwi-1270nm, 1290nm, 1310nm, 1330nm, 1330nm, 1350nm, 1370nm, 1390nm, 1410nm, 1430nm, 1410nm, 1450nm, 1450nm, 7m1 I-1530nm, 1550nm, 1570nm, 1590nm ukuya kwi-1610nm, apho i-1310nm kunye ne-1490nm ziyi-GPON Iindlela ezimbini zamaza optical optical forfiber ekhaya, i-1550nm sisiqulatho esiqhelekileyo sosasazo lwamaza ngokusetyenziswa kweamplifier yefiber optical. Isixhobo esiqhelekileyo se-Nch CWDM mux okanye i-de-mux kukupakishwa kwe-N-1 cascading CWDM izixhobo zesihluzi esinye.

Unxibelelwano lweFiber optic lutshintshile le planethi ukusukela ngo-1980. I-fiber yemowudi enye ineenzuzo zokugcinwa lula, ukuthomalalisa okuphantsi, uluhlu olubanzi lwamaza okukhanya kunye nedatha yesantya esiphezulu kwi-wavelength nganye ye-optical. Ukongeza, i-fiber inozinzo oluphezulu ekutshintsheni kweqondo lokushisa kunye neendawo ezahlukeneyo. Unxibelelwano lweFiber optic ludlala indima ebalulekileyo ukusuka kutshintshiselwano lolwazi lwelizwekazi ukuya kulonwabo losapho. Izixhobo ze-WDM, i-Fiber splitters kunye ne-fiber patchcords zizinto eziphambili kwi-passive network optical network (PON), exhasa i-multi-optical wavelengths esebenzisanayo ukusuka kwelinye iphuzu ukuya kwii-multi-indlela izicelo ezimbini. Kunye nezinto ezintsha kwizinto ezisebenzayo ezifana ne-laser, i-photodiode, i-APD kunye ne-optical amplifier, i-passive fiber optic components zenza i-fiber cable ifumaneke kumnyango wekhaya lababhalisi ngexabiso elifikelelekayo. Isantya esiphezulu se-intanethi, usasazo olukhulu lwevidiyo ye-HD imisinga ngaphezulu kwefayibha yenza le planethi ibe ncinci.

Isixhobo se-CWDM sinokusetyenziswa njengesixhobo esizimeleyo okanye sifakwe kwi-laser kunye ne-photodiode. Iphakheji ethandwayo yi-tube ye-fiber pigtail tube, ibhokisi yeplastiki yekhasethi, indlu ye-LGX kunye ne-19 "1RU chassis.
