Applications

Performance Specificationns Note: [1] For any given polarization. [2] All SOP , Measured over CCB of nearest-neighbor channels. [3] By design and DVT. [4] No epoxy on the optical path. [5] The mechanical tolerance should be +/-0.2mm on all package dimensions unless otherwise custom specified. * All parameter are without connector if no specified Green 25GHz Compact Fiber Optical Interleaver CFOI025 Series Oplink’s compact, low-dispersion interleavers greatly expand wavelength channel counts in DWDM systems. It is the best solution to upgrade exist - ing 50GHz spacing transport system. Oplink’s DWDM interleavers feature excellent wide, flat passband and high isolation. Both Mux and Demux func - tions are supported. These interleavers are athermal and therefore require no temperature control. Its stable center wavelength accuracy over C or L band 160 channels is suitable for higher bit rate application. The Green CFOI is compliant with industry green initiatives such as RoHS and WEEE.  Compact size  Low Dispersion  Completely passive  Ultra-low insertion loss  Highly stable & reliable  Epoxy-free optical path  Environmental green plan compliance  Metro and Long Haul DWDM system  Network capacity expansion  Signal comb filtering
