Embodiments relate to a local free space optical (FSO) terminal that transmits and receives optical beams. The FSO terminal includes a fore optic and a dispersive optical component. A receive (Rx) optical beam from a remote FSO terminal is received and focused by the fore optic to a Rx spot at a focal plane of the fore optic. A transmit (Tx) optical beam with a different wavelength forms a Tx spot at the focal plane and is collimated and projected by the fore optic to the remote FSO terminal. The dispersive optical component is positioned along optical paths of both the Rx beam and the Tx beam. Among other advantages, a wavelength dependence of the dispersive optical component laterally separates the Rx spot and the Tx spot at the focal plane.

A method and system for regenerating free space optical (FSO) signal pulses over free space optical (FSO) links. The FSO signal pulses are received over a first FSO link by a receiver telescope. The FSO signal pulses are split into a first part and a second part. The first part of the FSO signal pulses is converted to an electrical signal. The electrical signal is low pass filtered, amplified, and inverted to generate a negative electric voltage. The amplitude of the second part of the FSO signal pulses is attenuated by an optical absorber based on the negative electric voltage, thus regenerating the FSO signal pulses. The regenerated FSO signal pulses are amplified and bandpass filtered. The amplified and filtered regenerated FSO signal pulses are transmitted on a second FSO link.

[PROBLEM TO BE SOLVED] To uninterruptedly change a band of an optical transmission path in a line IF section, which relays a signal transmitted to an optical transmission path in a client IF section to which a communication terminal is connected, to the same band as a changed band in the client IF section without suspending the communication in the line IF section.

[SOLUTION] An optical transmission system 10A performs processing for changing a band of an optical fiber 15 in a line IF section (L section) that relays a signal from an optical fiber 12 in a client IF section (C section) to the same band as that in the C section. Line IF units 24A and 24B provided on both sides of the L section set a temporary evacuation lane p as an optical lane having a band different from those of a plurality of optical lanes 0 to n in the optical fiber 15 in the L section, selects either a change-target optical lane (for example, the optical lane 0) or the temporary evacuation lane p, the change-target optical lane being provided in the optical fiber 15 in the L section and having a band to be changed to a same band as a band in the C section, while causing a buffer unit 46 to absorb a delay difference between a signal received by the change-target optical lane and a signal received by the temporary evacuation lane p, and sets the optical lane not selected to have the same band as the band in the C section.
