The HOMS+OP+ are active multiplexers. Active multiplexers combine the functions of electrical-to-optical (E-to-O) transmitters and passive CWDM multiplexers into one dense module. Multiplexers have four or eight HD/SD/ASI inputs that are converted into four or eight optical wavelengths. The optical wavelengths are then optically multiplexed onto one single-mode fiber optic cable.
For each type of multiplexer, there are four variations corresponding to the upper eight, lower eight, upper four and lower four wavelengths of the standard ITU-T G.694.2 16 wavelengths. An optical “express port” allows cascading individual products to completely fill (all 16) CWDM wavelengths, thereby providing the greatest level of coarse wave division multiplexing efficiency.
