CWDM Add Drop Multiplexer suppliers OADM module (short for optical add-drop multiplexer), is a passive optical device used in WDM network system for multiplexing and routing different channels of light into or out of an current existing backbone ring.Add and drop here refer to the capability of adding one or more new wavelength channels to an existing multi channel WDM signals, dropping one or more channels passing those signals to another network path,so as to achieve the optical cross-connection. Arkoptics manufacture CWDM OADM 2CH Add Drop multiplexer,east and west, mux and demux in one ABS module equipped in one 1U 19” chassis. Customer can selected any CWDM 2 channels from ITU 1270nm to 1610nm range.Our 1U 19” Chassis will have clear channel port print (East-West) and COM-E, COM-W indications for easy patching. Customer logo can be printed on the front patch panel as well.At the meanwhile,we have mounting bracket on the chassis which can flexible to expand or reduce the mounting depth in datacenter cabinets. Features • Selected ITU wavelength from 1270nm to 1610nm • Available for CWDM OADM 1ch, 2ch, 4ch or 8ch multiplexer version • East and West,Mux and Demux in bi-directions • Additional Express/UPG port available • One ABS module in 1U 19” chassis rackmount • 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 COM-E, COM-W,channel East-West indications for easy patching • Mounting brackets for easy installation • Customized logo printing on the front patch panel Technical Specification Item Unit Parameters Channel spacing 20 nm ITU grids Wavelength rangenm1260 to1620 Channel centers (ITU or ITU+1)nm1270/1290...1610 or 1271/1291...1611 Passbandnm≥+/-6.5 Passband rippledB≤0.3 1CH OADM Add/Drop insertion lossdB≤0.8 dB 2CH OADM Add/Drop insertion lossdB≤1.0dB 4CH OADM Add/Drop insertion lossdB≤1.6dB Upgrade insertion loss (1 channel)dB≤0.8 dB Upgrade insertion loss (2 channel)dB≤1.2dB Upgrade insertion loss (4 channel)dB≤2.2dB Drop isolation (adj channel)dB≥30 dB Drop isolation (non-adj channel)dB≥50 dB Express isolationdB≥25 dB Polarization dependent lossdB≤0.2 dB Polarization mode dispersionps≤0.2 ps DirectivitydB≥50 dB Return lossdB≥45 dB Optical power handlingmW≤500 Operating temperature range°C-5 to 70 °C Storage temperature range°C-40 to +85 °C Fiber type SMF-28e with 0.9mm tube Connector Type LC,SC,FC,ST…… Package dimensionmmABS:100*80*10;1U 19” ChassisCWDM Add Drop Multiplexer suppliers website:http://www.arkoptics.com/cwdm-multiplexer/cwdm-add-drop-multiplexer/
