An optical diplexer module includes: an optical diplexer module comprising: a multiplexing unit multiplexing RF signals and a wideband digital signal having a baseband bandwidth to output a single multiplexed signal; an E-O converter converting the multiplexed signal into an optical signal and externally outputting the optical signal; and an O-E converter converting an externally received optical signal into an electric signal and outputting the electric signal. Similarly to existing optical transceivers, the optical diplexer module can provide TPS and MPS services using only two optical wavelengths for upstream and downstream signals. Since no separate optical wavelength is additionally required, the optical diplexer module can allows the numbers of components and processes to be reduced. It may result in yield improvement and cost reduction. Also, since electric or optical crosstalk between modules can be reduced, its performance can be improved.
