TEK P6703B Optical-to-Elecrical Converter

Features

The Tektronix P6700 Series optical-to-electrical (O/E) converters change optical signals into electrical signals for convenient analysis on Tektronix TDS Series oscilloscopes equipped with the TEKPROBE interface, or any other oscilloscope when used with the 1103 TEKPROBE power supply. The P6700 Series O/E converters are ideal for optical source characterization in the development, manufacture, or service of optical communication systems and devices.

Small, conveniently packaged P6701B and P6703B optical-to-electrical analog converters provide an accurate interface for optical pulse shape measurements. The high gain, large dynamic range and stable output offset of these O/E converters make them ideal for performing eye-pattern analysis and extinction measurements.

The P6723 optical logic probe provides a digital conversion of up to 650 Mb/s, NRZ optical signals and converts the data stream into a constant amplitude electrical 1 V pulse train. The P6723 has a sensitivity range similar to standard SONET/SDH optical receivers. It can be used as an optical interface to an electrical clock recovery circuit in support of data stream triggering or to a Bit Error Rate Tester (BERT). The LED on the P6723 indicates a valid optical input signal.

The P6701B/P6703B/P6723 optical input is a one meter, 62.5 µm multimode fiber with an FC/PC connector. Using the standard assortment of hybrid fiber optic mating sleeves, these O/Es can accommodate the various industry connector standards.

The TEKPROBE interface provides power, auto-scaling, auto-termination, and correct units (microwatts) when used with Tektronix TDS Series oscilloscopes.

The P6701B and P6703B can be transformed into ITU G.957 or ANSI FC-PH reference receivers when they are either ordered as an option (3C - P6701B, 4C - P6703B) to the latest Tektronix TDS 500C/700 Series digitizing oscilloscopes or as a standalone hardware solution (nominal).

The TDS Option 3C provides a calibrated P6701B reference receiver for Fibre Channel dates rates from 133 Mb/s up to 1063 Mb/s. Option 4C provides a calibrated P6703B reference receiver for SONET/SDH dates rates from 52 Mb/s up to 622 Mb/s. The optical-to-electrical convertors are matched and calibrated to a specific scope channel which ensures complete system compliance with the fourth-order Bessel-Thompson frequency response.

The P6703B, when used in conjunction with the FS52, FS156, or FS622 SONET/SDH hardware filters, provide customers with a nominal reference receiver performance for 51.84 Mb/s, 155.52 Mb/s, and 622 Mb/s.

The standard P6701B has a nominal frequency response which follows the fourth-order Bessel-Thompson for Fibre Channel 1063 Mb/s. The 1103 TEKPROBE power supply can be used to connect these products to the 11800 Series or CSA 803 Series sampling scopes.
