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 […]

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 […]

One of the great challenges facing data communications is matching the silicon bandwidth with the face plate density. Today, switch silicon can process over 12 Tb/s. But getting this off the front panel at a reasonable density is a challenge. One direction is to move to faster Ethernet speeds. A great example of this is […]

The ability to generate errors is a basic feature in most test sets, it can be used to establish if the receiver can detect and signal if errors occur. Of course, the VIAVI ONT has taken this to new levels with our advanced FEC stress tools used to validated and troubleshoot FEC correction logic and […]

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 […]

One of the questions we get asked now and then is on the connector life in our ONT products. Pluggable optical modules can be plugged in and out of our test sets, both as part of their test and validation but also in normal applications engineers will plug in and out different optical interfaces in […]

Growing up in Castleisland, County Kerry, my family was lucky to know the famous journalist Con Houlihan. With his fantastic command of the written word he was often asked to advise on the progress of young student’s written English by concerned mothers. Con’s stock reply would normally be ‘Well, they are making all the right […]

With the emergence of 400G Ethernet we have seen the wide deployment of higher order modulation in client interfaces.  We have moved from the mature NRZ of 100G and below to PAM-4 modulation both optically and electrically. This has allowed 400G links to be deployed for reaches of 10km. But what about applications like data […]

This is the first in a series of blog posts that offer technical and industry insights from Dr. Paul Brooks, who has been involved in R&D and product management for high speed electronic and photonic test equipment for over 20 years. Dr. Brooks holds several patents related to measurement in high speed test equipment and […]
