An Optical Time Slot Interchange (OTSI) Apparatus that has relatively low optical fiber requirements and good attenuation and signal-to-noise characteristics. This OTSI uses parallel feedback (PFB) to provide the delays. T his PFB OTSI can be implemented with an nxn optical crossbar switch. The PFB OTSI is conditionally, i.e., rearrangeably, non-blocking for 16x16 crossbar switch implementations if a controller using the control method of the invention is als o included.
