OCETS Plus is the evolution of the classic OCETS system that has been shipping for over a decade. The classic OCETS hardware specifications and software algorithms have been improved to meet the latest market requirements for optical component qualification testing, such as those driven by Verizon’s FOC program. At the core of OCETS Plus is a pair of custom-grade programmable switches (1xN configuration). OCETS switches are specified to higher levels of IL repeatability and background RL than analogue-grade switches. Therefore, the implementation of an OCETS Plus system represents an improvement over the capability of any in-house system that utilizes analogue-grade switches. In addition to the programmable switches, OCETS Plus is a hardware platform that comprises Fabry-Perot lasers, a source switch, directional switches, a polarization controller, high directivity couplers, and a power meter.
