Abstract
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. This PFB OTSI can be implemented with an n.times.n optical crossbar switch. The PFB OTSI is conditionally, i.e., rearrangeably, non-blocking for 16.times.16 crossbar switch implementations if a controller using the control method of the invention is also included.
