CWDM OADM

CWDM Optical Add/Drop multiplexer (OADM) is a passive optical device used in WDM networks for adding and dropping one/multiple CWDM channels into one or two fibers, while letting the rest of the wavelengths bypass to the needed destination.CWDM OADM modules are available in single-sided (East or West) and dual-sided (East and West) configurations supporting up to four wavelengths.Feature● Low insertion loss● Protocol transparent (support 1G, 10G etc.)● Based on thin film optics with epoxy free optical path● Fully compliant with Telcordia GR1221, GR1209, RoHS, ISO● Ideal for WDM ring structures or daisy chain applications● ADD<==>EXP, DROP<==>COM● Multiple packages availableSpecificationsParameter | Parameter | Unit | SpecificationWavelength Range | Wavelength Range | nm | 1260 ~ 1620Center Wavelength | Center Wavelength | nm | Customer specifiedChannel Spacing | Channel Spacing | nm | 20Passband | Passband | nm | CW±6.5Insertion Loss | COM==>DROP | dB | ≤1.5Insertion Loss | ADD==>EXP | dB | ≤1.5Adjacent Isolation | Adjacent Isolation | dB | ≥30Non-Adjacent Isolation | Non-Adjacent Isolation | dB | ≥45PDL | PDL | dB | ≤0.1Directivity | Directivity | dB | ≥50Return Loss | Return Loss | dB | ≥45PMD | PMD | ps | ≤0.1Power handling(CW) | Power handling(CW) | mW | ≤300Operating Temperature | Operating Temperature | ℃ | -10 to +70Storage Temperature | Storage Temperature | ℃ | -40 to +85Fiber Type | Fiber Type | G.657.A1 or G.652D | G.657.A1 or G.652DFiber Diameter | Fiber Diameter | 3.0mm or 2.0mm，0.9mm with loose tube | 3.0mm or 2.0mm，0.9mm with loose tubeConnector Type | Connector Type | LC/UPC or others | LC/UPC or othersFiber Length | Fiber Length | m | 1 or othersOptional Moniter port | Optional Moniter port | % | 1Package Dimensions | Package Dimensions | mm | ABS Cassete:100*80*10.5；140*115*18;ABS mini box：90x20x10；Steel tube :Φ5.5*38；LGX or 19 inch Rack fixedApplicationsApplications in WDM NetworkOrdering InformationOrdering Info. for OADMPart Number：SPWM-O-49A1-20-1LLU-A123 4567 8 9101112 Product Description：OADM Dual Fiber ABS Cassette 1 wavelength 1490nmADD/1490nmDROP G.657.A1 2.0mm Diameter 1M Fiber length with LC/UPC connector | Ordering Info. for OADMPart Number：SPWM-O-49A1-20-1LLU-A123 4567 8 9101112 Product Description：OADM Dual Fiber ABS Cassette 1 wavelength 1490nmADD/1490nmDROP G.657.A1 2.0mm Diameter 1M Fiber length with LC/UPC connector1 - Number of wavelengths | Null:1 wavelength; 2:2 wavelengths;2 - Type | O:OADM3 - Optional functions | M:Moniter port;4 - Wavelength | 27:1270nm; 29:1290nm; 31:1310nm; 33:1330nm; 35:1350nm; 37:1370nm; 39:1390nm; 41:1410nm; 43:1430nm; 45:1450nm; etc5 - Communication Type | S:Single fiber; Null:Dual fiber;6 - Fiber Type | D:G.652D; A1:G.657.A1;7 - Fiber Diameter | 20：2.0mm; 09：0.9mm with loose tube; Does not show in LGX and 19 inch Rack fixed8 - Fiber length | 1：1M or others; Does not show in LGX and 19 inch Rack fixed9 - COM ports | L :LC; S:SC; F:FC;10 - Other ports | L :LC; S:SC; F:FC;11 - Endface | U :UPC polish; P :PC polish; A :APC polish12- Package | A:ABS Cassette or mini ABS box; B:Steel tube; L:LGX; R:19 inch Rack fixed
