While evaluating high-speed network test equipment, it may be tempting to forgo deep physical layer testing capabilities to save money and reduce testing complexities. In some cases, these ‘just good enough’ solutions appear to fit the bill, but lack of deep insights can lead to product re-designs, longer development cycles or systemic failures in the […]
Since the emergence of 400 Gigabit Ethernet (GbE) around 5 years ago, we have seen PAM-4 modulation replace NRZ on both optical and electrical interfaces. We now see a broad and healthy ecosystem building for 400 GbE, and even 800 GbE, using PAM-4 signaling. In fact, we are even seeing the first 100 Gb per […]
Pluggable coherent optics really hit mainstream in 2022 and a big part of that was the multi-vendor ZR interop at the OIF booth at OFC 2022. It was great to be involved in this public event as we have been involved in the background for many years supporting the pluggable coherent ecosystem from the earliest […]
While you are walking the OFC 2023 trade show floor in San Diego, you may notice VIAVI ONT-800 setups in various booths, helping manufacturers demonstrate the performance of their products to their own customers. One manufacturer using VIAVI gear is InnoLight Technology Ltd., a global manufacturer of high-speed optical transceivers in booth #4115. New InnoLight […]
800G is becoming a talking point and it is one topic that can mean different things to different people. The main thrust today is development of 800G class pluggable modules. We are seeing the first 800G modules, both QSFP-DD800 and OSFP-800 appearing in the market. Although they carry an 800G tag they are really focused […]
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 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 […]
