Our optical transmitters allow the generation of optical signals of up to 100 Gbps. In addition to the well-known ASK format (also known as OOK), we also produce instruments for the generation of DPSK, DQPSK and duobinary signals.

A range of optical receiver plug-in modules is available to enable electrical BER measurements of ASK and DPSK optical data streams. The DPSK receivers are also well suited for the separate analysis of the I and the Q channel of an DQPSK modulated signal. Our clock recovery solutions are completing the measurement capabilities for optical transmission system research.
