The ONT family has established itself as the reference for module development and validation. This pedigree continues with our ONT-800 family covering both QSFP-DD and CFP2 pluggable digital coherent optics (DCO). Developing and validation of DCO has many new challenges and having a stable test and development environment is key to reliable product validation and […]

Pluggable coherent optics offer advantages in many areas. One of the biggest factors is electronic dispersion compensation. For DCI, traditional ‘direct detect’ systems needed a detailed pre-planned link with dispersion compensation ‘engineered in’. This is both expensive and challenging to deploy. Scaling and maintaining are complicated. Electronic dispersion compensation inside the DSP of coherent modules […]

With the move to pluggable coherent optical modules for the first time since 10G, we see client and line side considerations coming together. The most obvious example of this is optical signal to noise (OSNR) and related measurements. For any modules with the potential for use in an amplified system, OSNR becomes the fundamental figure […]
