Green 25GHz Compact Fiber
Optical Interleaver
CFOI025 Series
Product Description
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 andWEEE.
