cheap DWDM Multiplexer 8ch DWDM multiplexer with 1% Monitor and Upgrade port 1500-1620nm.Any 8ch wavelength on ITU channel range of C- or L-band 186.6 to 196.1THz with 100GHz and 200GHz space are available. Arkoptics manufacture 100G DWDM 8ch with 1%monitor and UPG Mux Demux modules.We are using 1x2 splitter with 1% ratio as monitor port in the 8CH DWDM multiplexers.It can works as network link monitoring and network power monitoring which can do great favor for easy trouble-shooting without affecting current network traffic.Commonly the attenuation loss on the monitor port is less than 23dB. At the meanwhile,we will keep an upgrade port(UPG 1500-1620nm) to 8CH DWDM muxes which can double the fiber channel capacity on the existing 8ch DWDM fiber network without the need for installing or leasing additional fibers. We will equip both 8CH DWDM Mux and Demux Modules in 1U 19”chassis.Our 1U 19”Chassis will have clear channel port prints and Tx Rx indications for easy patching in datacenter.Customer logo can be printed on the front patch panel as well.At the meanwhile, We have mounting bracket on the 1U chassis which will be much flexable to expand or reduce the mounting depth during installation in datacenter cabinets Features • 8ch DWDM Mux Demux with Monitor and UPG( 1500-1620nm) port • 1%,2%,3%,5% split ratio monitor available • Common attenuation less than 23dB on the monitor port • Come with 900um,2.0mm or 3.0mm patches • Can terminated with LC,SC,FC,ST and other types of optical connectors • 1U 19”chassis have Tx Rx prints and channel indication for easy patching • Mounting brackets for easy installation • Customized logo printing on the front patch panel Technical Specification Item Unit Parameters Wavelength range C- or L-band ITU channels 186.6 to 196.1 THz Channel centersnmITU ChannelsCHDWDM 8CH with Monitor and UPG PassbandGHz100GHz≥+/-12.5200GHz≥+/-33 Passband rippledB ≤0.5 Channel insertion lossdB2.82.8 UPG(1500-1620nm) insertion lossdB2.6 Monitor port insertion lossdB≤23 Isolation (adjacent channel)dB≥30 Isolation (non-adjacent channel)dB≥50 Polarization dependent lossdB≤0.2 Polarization mode dispersionps≤0.2 DirectivitydB≥50 Return lossdB≥45 Optical power handlingmW≤500 Operating temperature range°C-5 to 70 °C Storage temperature range°C-40 to +85 °C Fiber type SMF-28e Connector Type LC,SC,FC,ST…… Package dimensions (L x W x H)mmABS:100 x 80 x 10;1U 19”Chassischeap DWDM Multiplexer website:http://www.arkoptics.com/dwdm-multiplexer/
