How to use Red Blue filter for DWDM single fiber transmission system?
For the red blue filter, red band is C21-C37 and blue band is C44-C60. For long distance transmission, you can use EDFA to amplify the optical power of Tx.
As we know, DWDM SFP Optical Transceivers are all duplex LC package, Tx and Rx. We can use Red band channel as Tx and Blue band channel as Rx, combine Tx and Rx into single fiber by using Red Blue filter.
