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 […]
We’re excited to announce that VIAVI Solutions is back and in-person for OFC 2022, March 8-10 in San Diego. Come join us in booth #3727 as our technology experts will be on hand to help you accelerate high-speed network test from design and production to field tests and troubleshooting. We have a full slate […]
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 […]
Pluggable optical modules are a huge success factor in modern networking equipment. An end user can buy a network element, such as a router or switch, and provision ports in a pay-as-you-grow manner. They can plug optical modules into the ports and chose the reach (from a few meters with DAC copper through to 100’s […]
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 […]
