ABSTRACT:
An optical two-way transmission-received communications system utilizing a coaxial coupler in place of a standard coupler, the optical system being capable of operation either in a single or multiple wavelength mode by designing the coupling region to have the proper length (i.e., either in 3dB or WDM operation), and further comprising a transmitter and a detector adjacent a coaxial coupler. The detector of the system is provided with a hole in its center in order to allow the transmitter access to the core waveguide of the coaxial coupler. The coaxial coupler may be formed from a rod in tube structure with a core waveguide extension adjacent the Tx/Rx and an integral pigtail on the opposite side of the coupler.
