SDH Optical Transmitter and Receiver Module

SDH Optical Transmitter and Receiver Module

This product is designed to provide high optical performance for SDH STM-1/SONET OC-3. Transmitter uses uncooled laser in a hermetic pigtail coaxial module with drivered by specific integrated circuit. For intra-office and intermediate-reach applications, the transmitters are configured to operate at SDH/SONET. The Tektronix high-performance OI1125 E/O transmitter and OI2125 O/E receiver offer a simple and cost-effective solution for generating and receiving SONET/SDH compliant optical signals for bit error rate (BER) testing and optical signal analysis up to 12. The TR-PX15Z-NSN converts a 10Gb/s serial electrical data stream to 10Gb/s optical output signal and a 10Gb/s optical input signal to 10Gb/s serial electrical data streams. [pdf]
