The devices combine or separate light at different wavelength in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. These components have extensively used in EDFAs, raman amplifier, fiber sensor system, WDM networks and fiber optics instrumentation.Featuresonthinfilmfiltertechnologyand high wavelength stabilitypolarization dependent lossand high channel isolationFlat and wide passbandEpoxy free optical path and excellent reliabilityTelcordiaGR-1221-COREqualified andRoHS compliantApplicationsWDM systemCATV systemTelecommunication network systemMetro/Access networksEDFAFiber optic instrumentsTransmitters and fiber lasersSingle direction/Bi-direction transmissionLine monitoringFTTXSpecificationParameterUnitValueCentral Wavelengthnm850/1310980/15501310/15501480/15501310/1490/1550C/L Band1310/16251550/1625WavelengthType1Passbandnm850±50980±401310±401450~14901310±40 1490±101528~15631310±401550±40Reflective Band1310±501550±401550±401530~15801530~15801570~16101625±101625±10Type2Passband1310±501550±401550±401530~15801530~15801570~16101625±101625±10Reflective Band850±50980±401310±401450~14901310±40 1490±101528~15631310±401550±40Insertion LossPass ChanneldB≤0.6Reflective Channel≤0.4IsolationPass ChannelnmStandard ISO≥30, High ISO≥40Reflective ChannelStandard ISO≥15, High ISO≥20FlatnessdB≤0.3DirectivitydB≥50Return LossdB≥45PMDps≤0.10PDLdB≤0.10Insertion Loss Temperature SensitivitydB/°C≤0.005Wavelength Temperature Shiftingnm/°C≤0.002Fiber Type-50/125 or 62.5/125 Multimode fiber, SMF-28e Single mode fiber, HI1060 FiberMax.
