Hi,
I would suggest you to
apply dense wavelength division multiplexing
(DWDM) to the system will be a strong candidate
in order to support all of BS’s for fiiture fiber-optic
access network infrastructure. There have been
several reports on such DWDM radio-on-fiber
systems -[3]. To increase the spectral efficiency
of the system, the concept of optical frequency
interleaving was first proposed by Schaffer et al.
by simultaneous upconversion scheme with an
electro-optic modulator [4]. Recently, a simple
method to increase the spectral efficiency by
optical frequency interleaving was proposed in
which the modulation format could be either
optical double side band (DSB) or optical single
side band (SSB).The transmitted signal (A) is fed to a
high-Finesse Fabry-Perot etalon (FP) through an
optical circulator (OC). Thc free spcctral range of
the FP is adjusted to cqual to the channel spacing.

Thanks,
