Probe of two-way optical component network analyzer

摘要

A probe of two-way optical component network analyzer. The probe includes an electrical circulator, an optical transmitter, an optical receiver, and an optical circulator. The electrical circulator is connected to a network analyzer, an optical transmitter and an optical receiver respectively. Electrical signals from the network analyzer are sent to the optical transmitter via the electrical circulator. The electrical circulator is capable of picking up electrical signals from the optical receiver and transmitting the electrical signals back to the network analyzer. Since electrical signals from different devices are separated inside the electrical circulator, electrical interference is prevented. The optical circular is coupled to the optical element, the optical transmitter and the optical receiver respectively. The optical circulator directs optical signals from the optical transmitter to the optical element and transfer optical signals from the optical element to the optical receiver. Since optical signals from different source are de-coupled inside the optical circulator, optical interference is prevented. The optical transmitter is a device for converting electrical signals to optical signals, and the optical receiver is a device for converting optical signals back to electrical signals.
