| Message: | The Coarse Wavelength Division Multiplexing is also known as CWDM MUX or passive CWDM multiplexer. This thin-film filter technology integrates multiple wavelength channels over one physical medium. At multiplexing side the wavelength channels are "muxed&" together to go over the dark fiber. At the de-multiplexing end this is reversed in the process of "demuxing&" the wavelength channels.Our 4 Channel CWDM Multiplexer ranges from 1270nm to 1610nm,Website:http://www.arkoptics.com, customer can choose any 4 channel wavelength to be used on the network project, such as 1270nm to 1330nm, 1510nm to 1570nm, 1550nm to 1610nm. 4CH CWDM Mux Demux,They can go for 1G, 10G, 40G, and 100G network speed.Features • Available in any 4channel ranges from 1270 to 1610nm • UPG/Express port optional • Come with 900um,2.0mm or 3.0mm patches • Can terminated with LC,SC,FC,ST and other types of optical connectors • Epoxy-free optical path • Exceptionally stable and reliable • Widely used in access network and metro WDM systemTechnical Specification Item Unit Parameters Wavelength rangenm1260~1620Channel centers (ITU or ITU+1)nm1270/1290…1610 or 1271/1291…1611ChannelsCH4CH8CHPassbandnm≥+/-6.5Passband rippledB≤0.5Channel insertion lossdB2.02.8Optional UPG/Express insertion lossdB1.82.6Isolation (adjacent channel)dB≥30Isolation (non-adjacent channel)dB≥45Polarization dependent lossdB≤0.2Polarization mode dispersionps≤0.2DirectivitydB≥50Return lossdB≥45Optical power handlingmW≤500Operating temperature range°C-5 to 70 °CStorage temperature range°C-40 to +85 °CFiber typeSMF-28eConnector TypeLC,SC,FC,ST,E2000……Package dimensions (L x W x H)mm100 x 80 x 10 |
