Optical device models for RoF systems

This paper studies engineering design and modeling of an optical device intended for Radio-over-Fiber (RoF) antenna array radio emitting management. Design and assembled models of the device are based on either profiled multiple-wave interferometer or long-haul ring topology FOCL. To construct the interferential type OSCD (optical signal splitting and chirping device) models optical ceramic glass mixer processed with the ITHP (intense twist under high pressure) method was used. Loss and transmission coefficients with account of splitting for all the prototype units were measured — on frame-controller equipment and on RoF segment test bench equipment. Satisfactory measurement results obtained allow to make conclusion on OSCD models applicability for RoF test segments. The designed models and test bench pictures are also illustrated in this article.
