Tektronix Programmable Optical Attenuators provide a convenient, accurate and cost-effective means of controlling optical power levels in fiber optic media. The OA5002 instrument provides variable attenuation of single-mode fiber optic signals commonly used in communications equipment. Attenuation levels can be varied manually, using the front-panel controls or automatically via programmable, IEEE-488.2 interface. The single filter design eliminates measurement dark spots caused by "range changes" and an internal mechanical motion algorithm provides outstanding repeatability.
Communication standards using optical components typically require that the receiver operate over a given optical power range. This specification is tested by monitoring the bit error rate (BER) as a function of optical power.
Transmission System Design
Using the OA5002 Optical Attenuator with either the TDS/CSA8000, CSA803, 11800 or TDS700C/500C oscilloscopes, network equipment designers can characterize, with repeatable results, the system performance over the specified optical power range.
SDH/SONET Compliance Testing
SDH/SONET compliant signal levels may be as high as +2 dBm to as low as -34 dBm. To verify the performance of SONET equipment over these signal levels, it is necessary to have calibrated attenuators with at least this much range. The OA5002 is the attenuator of choice for SDH/SONET testing.
Manufacturing and Other Automated Test Applications
Because the OA5002 Optical Attenuator is GPIB Programmable, these units can be operated in a completely automated environment. With the step size of 0.01 dB and a calibrated attenuation range of 0 to 60 dB (continuous), measuring parameters, such as receiver linearity, is quickly and reliably accomplished. Also, with its storable attenuation levels, the OA5002 Optical Attenuator are very useful for repeat measurements in manufacturing environments.
