100km RF over Fiber Link is a Potential Game Changer for Teleports says ViaLite CEO

Bradenton, Florida 7th March 2014 ViaLite Communications have announced a 100km RF over fiber link that does not need optical repeaters. "Customers have been asking us for longer link distances, so we are very pleased to announce this new product ahead of the Satellite2014 exhibition in Washington" says Dr. Martin Ryan, CEO of ViaLite Communications. "Very long link distances open up new possibilities for teleport design and this kind of capability is a potential game-changer. For example, multiple teleport sites can be controlled from a single control room. The ViaLite 100km link also supports DWDM and the multiplexing of timing or reference signals together with traffic and the link can be controlled remotely using Ethernet or SNMP.

"We have been manufacturing these links for twenty years. RF over fiber is becoming the de-facto choice for inter-facility links (IFLs) because teleports are getting larger and copper coax is no longer suitable. The electrical signal is transferred to the optical domain without any modulation so the link is completely transparent to the system and supports any signal format. Customers can therefore install RF over fiber links knowing they are future-proof.

"Fiber losses are so low that even our standard links support up to 10km. In fact, with these longer link distances and DWDM, it is now commercially and technically viable for teleports to use dark (leased) fiber. ViaLite customers are already providing live services to major broadcasters over leased fiber. DWDM means up to 96 links can share a single fiber. Using more than one fiber loop allows full redundancy and link gain can be automatically or manually adjusted so the fiber loops appear identical in the system, even if they are radically different lengths."

ViaLite RF over fiber links are available in 19" rack format or as OEM modules for integrating with existing systems. The 100km link supports frequencies up to 3GHz and is compatible with the Satcom6, an intelligent weatherproof outdoor enclosure designed specifically for use at teleports. ViaLiteHD platform is a finalist in this year's World Teleport Association (WTA) teleport technology of the year 2014.

ViaLite Communications will be at Satellite2014 in Washington from March 11th-13th on booth number #9029. More information can be found at www.vialite.com. Email: [email protected] or call +1 (855) 4-VIALITE in the USA, +44 (0)1793 784389 in the UK.

"I think that everyone recognizes that for IoT to really realize its full potential and value that it is about creating ecosystems and marketplaces and that no single vendor is able to support what is required," explained Esmeralda Swartz, VP, Marketing Enterprise and Cloud at Ericsson, in this SYS-CON.tv interview at @ThingsExpo, held June 7-9, 2016, at the Javits Center in New York City, NY.
Most companies are adopting or evaluating container technology - Docker in particular - to speed up application deployment, drive down cost, ease management and make application delivery more flexible overall. As with most new architectures, this dream takes a lot of work to become a reality. Even when you do get your application componentized enough and packaged properly, there are still challenges for DevOps teams to making the shift to continuous delivery and achieving that reduction in cost ...
Why do your mobile transformations need to happen today? Mobile is the strategy that enterprise transformation centers on to drive customer engagement. In his general session at @ThingsExpo, Roger Woods, Director, Mobile Product & Strategy – Adobe Marketing Cloud, covered key IoT and mobile trends that are forcing mobile transformation, key components of a solid mobile strategy and explored how brands are effectively driving mobile change throughout the enterprise.
After more than five years of DevOps, definitions are evolving, boundaries are expanding, ‘unicorns’ are no longer rare, enterprises are on board, and pundits are moving on. Can we now look at an evolution of DevOps? Should we? Is the foundation of DevOps ‘done’, or is there still too much left to do? What is mature, and what is still missing? What does the next 5 years of DevOps look like? In this Power Panel at DevOps Summit, moderated by DevOps Summit Conference Chair Andi Mann, panelists l...
My team embarked on building a data lake for our sales and marketing data to better understand customer journeys. This required building a hybrid data pipeline to connect our cloud CRM with the new Hadoop Data Lake. One challenge is that IT was not in a position to provide support until we proved value and marketing did not have the experience, so we embarked on the journey ourselves within the product marketing team for our line of business within Progress. In his session at @BigDataExpo, Sum...
Virtualization over the past years has become a key strategy for IT to acquire multi-tenancy, increase utilization, develop elasticity and improve security. And virtual machines (VMs) are quickly becoming a main vehicle for developing and deploying applications. The introduction of containers seems to be bringing another and perhaps overlapped solution for achieving the same above-mentioned benefits. Are a container and a virtual machine fundamentally the same or different? And how? Is one techn...
Keeping pace with advancements in software delivery processes and tooling is taxing even for the most proficient organizations. Point tools, platforms, open source and the increasing adoption of private and public cloud services requires strong engineering rigor - all in the face of developer demands to use the tools of choice. As Agile has settled in as a mainstream practice, now DevOps has emerged as the next wave to improve software delivery speed and output. To make DevOps work, organization...
MongoDB Atlas leverages VPC peering for AWS, a service that allows multiple VPC networks to interact. This includes VPCs that belong to other AWS account holders. By performing cross account VPC peering, users ensure networks that host and communicate their data are secure. In his session at 20th Cloud Expo, Jay Gordon, a Developer Advocate at MongoDB, will explain how to properly architect your VPC using existing AWS tools and then peer with your MongoDB Atlas cluster. He'll discuss the secur...
Without a clear strategy for cost control and an architecture designed with cloud services in mind, costs and operational performance can quickly get out of control. To avoid multiple architectural redesigns requires extensive thought and planning. Boundary (now part of BMC) launched a new public-facing multi-tenant high resolution monitoring service on Amazon AWS two years ago, facing challenges and learning best practices in the early days of the new service.

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm.
