Verification of SONET/SDH Signals

The Synchronous Digital Hierarchy (SDH) and the Synchronous Optical NETwork (SONET) standards are the cornerstones of today's high-speed digital telecommunications systems. The Tektronix ORR24 optical reference receiver provides an important interface for compliance testing of SDH/SONET optical transmission products or components.

The amplified design of the ORR24 converts the incoming optical light into a high gain, low noise electrical signal. This allows easy testing of optical designs as well as repeatable measurements. The ORR24 is DC coupled which is required for accurate extinction ratio measurements.

The controlled frequency design of the ORR24 optical reference receiver ensures that the measurements correctly represent the true transmitted signal for the purpose of pulse shape analysis or eye-pattern measurements. A certificate of calibration and a frequency response graph are supplied with the ORR24 for performance documentation. The compact SDxx form factor enables the ORR24 to conveniently plug into the Tektronix 11800 or CSA803 Series sampling oscilloscopes for complete compliance testing. An optional power supply is available for other instrument applications.
