Reflective phase compensator (RPC) filters provide a solution to the phase-dispersion problem of narrow bandpass (NBP) filters when the data rate is 40 Gbits/s or greater. By use of an RPC filter to compensate for the excessive group-delay (GD) ripple of an NBP filter, the GD ripple of the combined NBP+RPC filter is well under the required 2.5 ps.
