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 […]
Balancing test equipment availability with tight budgets and aggressive timelines can be challenging for any product development group. PCI Express® engineering teams are especially impacted, given the cost of equipment and pressure to get products to market quickly—even as testing environments become increasingly more complex. Product development teams have similar goals Faster debug for quicker […]
Analyzer Bifurcation enables simultaneous multiple tests by multiple remote users so your testing can be completed faster Traditionally, PCI Express® protocol analysis is performed with one user conducting a single test on a dedicated, single function Analyzer. Now, multiple users can log into one VIAVI Xgig® 5P16 or 5P8 Analyzer at the same time to […]
Over the past few months, teams have been very busy developing 400G class pluggable optical modules. Both as QSFP-DD, predominantly for -ZR 80km applications, and CFP2 for full multi-service DWDM. These coherent modules are a complex mix of photonics, high speed electronics, DSP and firmware as well as mechanical and thermal engineering and we at […]
Viavi Solutions Inc. (VIAVI) will showcase this week a range of products engineered to simplify and accelerate high-speed network test across all phases of the network lifecycle including development and system verification, manufacturing, turn up and installation, and troubleshooting and monitoring. The new products highlight the VIAVI presence at OFC 2021, taking place virtually from June […]
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 […]
