Product Description

CWDM-55 yog 1550nm CWDM mux los yog demux ntaus ntawv nrog built-in 1550nm lim uas ntxiv 1550nm teeb liab mus rau qhov chaw nres nkoj com lossis poob 1550nm teeb liab los ntawm qhov chaw nres nkoj com. CWDM-xx series ntaus ntawv yog qhov zoo tagnrho rau ntxiv lossis poob xx CWDM channel rau fiber ntau optic. CWDM tus qauv wavelength ntau ntawm 1270nm, 1290nm, 1310nm, 1330nm, 1330nm, 1350nm, 1370nm, 1390nm, 1410nm, 1430nm, 1451070nm, 1530nm, 1550nm, 1570nm, 1590nm txog 1610nm, qhov twg 1310nm thiab 1490nm yog GPON ob-txoj kev kho qhov muag wavelengths rau fiber ntau rau hauv tsev, 1550nm yog qhov kev tshaj tawm cov ntsiab lus wavelength los ntawm kev siv cov khoom siv kho qhov muag fiber ntau. Nch CWDM mux los yog de-mux ntaus ntawv yog stacking ntawm N-1 cascading CWDM ib lim li.

Fiber optic kev sib txuas lus tau hloov lub ntiaj teb no txij li xyoo 1980s. Ib hom fiber ntau muaj qhov zoo ntawm kev saib xyuas yooj yim, tsis tshua muaj attenuation, dav optical wavelength ntau thiab cov ntaub ntawv ceev ceev ntawm txhua qhov kho qhov muag wavelength. Tsis tas li ntawd, fiber ntau muaj kev ruaj ntseg ntawm qhov kub thiab txias thiab ntau qhov chaw. Fiber optic kev sib txuas lus tau ua lub luag haujlwm tseem ceeb los ntawm kev sib pauv ntaub ntawv sib txuas mus rau tsev neeg kev lom zem. WDM cov khoom siv, Fiber splitters thiab fiber ntau patchcords yog cov khoom tseem ceeb hauv passive optical network (PON), txhawb nqa ntau qhov kho qhov muag wavelengths co-ua hauj lwm los ntawm ib qho taw tes rau ntau cov ntsiab lus ob txoj kev siv. Ua ke nrog kev tsim kho tshiab ntawm cov khoom siv xws li laser, photodiode, APD thiab optical amplifier, passive fiber optic Cheebtsam ua fiber ntau cable muaj nyob rau ntawm lub qhov rooj ntawm cov neeg siv khoom lub tsev ntawm tus nqi pheej yig. Kev kub ceev hauv internet, kev tshaj tawm xov xwm loj HD video ntws hla fiber ntau ua rau lub ntiaj teb me me.

CWDM ntaus ntawv tuaj yeem siv los ua khoom siv ib leeg lossis kos rau hauv laser thiab photodiode. Cov pob nrov yog peb lub raj fiber ntau, lub thawv yas yas, LGX vaj tsev thiab 19 "1RU chassis.
