CWDM Module

CWDM Module is usually act as the internal unit of CWDM MUX/DEMUX, it is usually designed to be ABS Cassettes. They can be quick Installed in Various Boxes.1*2 CWDM filter is usually a Steel tube or a mini ABS box.Feature● Low insertion loss● Based on thin-film filter technology● Multiplexing of up to 16/8 channels on fiber pair/single fiber● Standard CWDM band 1470 nm - 1610 nm, 20 nm spacing● Compliant to ITU-T G.694.2 standard and Telcordia GR1209, GR1221● LC/SC/FC/ST, UPC/APC connectors are available● Rate transparent for applications up to 10Gbps● Monitor/Upgrade/1310nm Express port for external functions● Completely passive, no electric power requiredSpecificationsParameter | Unit | SpecificationOperating Wavelength Range | nm | 1260~ 1620Center Wavelength | nm | Customer specified 4，8 or 16 wavelengths etcChannel Spacing | nm | 20Pass band | nm | CW±6.5Insertion Loss(WithConnector) | dB | ≤2.5Adjacent Channel Isolation | dB | ≥30Non-Adjacent Isolation | dB | ≥45Reflection Channel Isolation | dB | ≥15PDL | dB | ≤0.2Directivity | dB | ≥50Return Loss | dB | ≥45PMD | ps | ≤0.1Optical Power | mW | ≤500Operating Temperature | ℃ | -10 to +70Storage Temperature | ℃ | -40 to +85Fiber Type | G.657.A1 or G.652D | G.657.A1 or G.652DFiber Diameter | 2.0mm or 0.9mm with loose tube | 2.0mm or 0.9mm with loose tubeFiber Length | 1：1M or others | 1：1M or othersConnector Type | LC/UPC or others | LC/UPC or othersCommunication Type | Single or Dual Fiber | Single or Dual FiberOptional functions | 1310 Express port: 1310+/-40nm;Upgrade port: Unused wavelength section；Moniter port: 1%; | 1310 Express port: 1310+/-40nm;Upgrade port: Unused wavelength section；Moniter port: 1%;Packaging Dimension | CWDM Module :100*80*10.5；140*115*18;1*2 WDM filter:Φ5.5*38；90x20x10 | CWDM Module :100*80*10.5；140*115*18;1*2 WDM filter:Φ5.5*38；90x20x10Note：The specific parameters are subject to the product specifications.ApplicationsApplications in CWDM NetworkOrdering InformationOrdering Info. for CWDM ModulePart Number：SPWM-4MU-C47A1-20-1LLP-A 123 456 7 8 9101112 13 14Product Description：CWDM Module Dual Fiber ABS Cassette with Upgrade Port 2× 4 wavelengths 1470nm-1530nm G.657.A1 2.0mm Diameter 1M Fiber length with LC/PC connector | Ordering Info. for CWDM ModulePart Number：SPWM-4MU-C47A1-20-1LLP-A 123 456 7 8 9101112 13 14Product Description：CWDM Module Dual Fiber ABS Cassette with Upgrade Port 2× 4 wavelengths 1470nm-1530nm G.657.A1 2.0mm Diameter 1M Fiber length with LC/PC connectorOrdering Info. for WDM FliterPart Number：SPWM-F-55A1-09-1SSA-B12 5 7 8 9 101112 13Product Description：1x2 WDM filter Steel tube 1550nm Pass G.657.A1 0.9mm Diameter with loose tube 1M Fiber Length with SC/APC connector | Ordering Info. for WDM FliterPart Number：SPWM-F-55A1-09-1SSA-B12 5 7 8 9 101112 13Product Description：1x2 WDM filter Steel tube 1550nm Pass G.657.A1 0.9mm Diameter with loose tube 1M Fiber Length with SC/APC connector1 - Number of wavelengths | Null:1 wavelength; 4:4 wavelengths; 8:8 wavelengths; 16:16 wavelengths; etc2 - Type | M:CWDM Module F:1x2 WDM filter3 - Optional functions | E:1310nm Express port; F:1550nm port; M:Moniter port; U:Upgrade Port4 - Standard | C:Compatible with ITU-T G.694.2;5 - First wavelength | 27:1270nm; 29:1290nm; 31:1310nm; 33:1330nm; 35:1350nm; 37:1370nm; 39:1390nm; 41:1410nm; 43:1430nm; 45:1450nm; etc6 - Communication Type | S:Single fiber; Null:Dual fiber;7 - Fiber Type | D:G.652D; A1:G.657.A1;8 - Fiber Diameter | 20：2.0mm; 09：0.9mm with loose tube9 - Fiber length | 1：1M or others10 - COM ports | L :LC; S:SC; F:FC;11 - Other ports | L :LC; S:SC; F:FC;12 - Endface | U :UPC polish; P :PC polish; A :APC polish13- Package | A:ABS Cassette or mini ABS box; B:Steel tube;14 - Additional parameters | A31:Add 1310nm; S47:Skip 1470nm; etc
