In case the transmitter has TEM or quasi-TEM output connections, instead, a dual-polarization antenna often presents separate connections ( i . e . a printed square patch antenna with two feed points ), and embeds the function of an OMT by means of intrinsically transferring the two excitation signals to the orthogonal polarization states.

The new spectral sidebands are characterized by the fact that their positions on the soliton's spectrum vary with the strength of the linear cavity birefringence, and while one polarization component's sideband has a spectral peak, the orthogonal polarization component has a spectral dip, indicating the energy exchange between the two orthogonal polarization components of the vector solitons.

The variable attenuator made in this fashion is not recommended for attenuation for beam profiling applications because : ( 1 ) the beam profile in the two orthogonal polarizations may be different, ( 2 ) the polarization beam cube may have a low optical damage threshold value, and ( 3 ) the beam can be distorded in cube polarizers at very high attenuation.
