One of the most significant areas we have seen driving new test and measurement requirements has been data center interconnect – DCI. This rapidly growing area leverages the emergence of pluggable coherent optics (DCO) to allow rapid scaling of data center interconnect bandwidth based on an open, multi-vendor ecosystem. For the DCI market to grow […]

As module bitrates increased from 100Gbs so too did the complexity of the modules. Starting with DSP based signal conditioning and clock recovery and onwards to pluggable coherent optics, PAM-4 and CMIS. With this new level of complexity, we had to take a very different approach to module-to-pluggable optics development, debugging and validation. Specifically, the […]

VIAVI recently participated in, and was a Gold sponsor of, the High Speed Networking event held by LIGHTWAVE and the Broadband Technology Report. During the event, experts from VIAVI participated in several webcasts that are now available to stream for free. Before you view either, you will have to register (for free). Once you register, […]

If you would like a more in-depth review of what the path forward with 800G pluggable optics may look like may we suggest watching Preparing the Way for 800G: 100G Electrical and 800G Pluggable Optics. —————————————————————————————————————————————————————————————– The creation of the 800G ecosystem has begun. Alpha samples of 800G OSFP modules have been demonstrated and we […]

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 […]
