Compact, low cost optical transmitter

In addition to the clock synthesizer, dual-channel BPG and dual-channel EA, an optical transmitter (EO converter) is now available for component and module testing.

This compact instrument, the SHF 46120 A, supports both 1300 and 1510 nm industry standard wavelength bands (O- and C-bands) with low insertion loss of less than 5 dB.  Its other key features include:

  • Data rates from 1 to 44 Gbps ASK (OOK) modulation,
  • Automatic bias control for modulator stability,
  • Adjustable extinction ratio via input data amplitude control,
  • PAM capable,
  • External interference injection for optical stress eye generation.

Combining the jitter injection capability of the clock synthesiser, adjustable output amplitude and pre-emphasis feature of the BPG, and now the broad band optical transmitter, the set up can support a comprehensive range of stress tests required for 100G modules and components.

An example of the output eye pattern is shown below:
