Challenges for Hyperscale Networks

Arguably the biggest challenge for hyperscalers is continuity and, by association, reliability. New findings generated by a survey from Uptime Institute revealed that over 10% of all respondents said their most recent reportable outage cost them more than $1m in direct and indirect costs. On March 13th, 2019, Facebook suffered its worst-ever outage, affecting the estimated 2.7 billion users of its core social network, Instagram and messaging applications, Facebook Messenger, and WhatsApp. By extrapolating the company’s 2018 revenue figures, CCN estimated that the blackout could have cost Facebook up to $90 million in lost revenue based on an income of $106,700 per minute. With so many businesses relying on hyperscale data centers to provide the IT backbone to their operations, any downtime can have a substantial impact and sometimes catastrophic ramifications.

Researchers develop world’s top-class 400-Gbps optical engine

Researchers in South Korea have developed ultra-fast transmitting/receiving optical engine that can provide stable and improved data transfer speed for data centers. The new technology sends eight times as much data as conventional methods in each linecard/server. It is expected to contribute to solving data traffic congestion in data centers where the demand for fast data speed has increased due to high-definition video content and services using artificial intelligence and cloud computing.

Webinar: Single-Mode Fiber: The Perfect Fit For Your Evolving Enterprise

Until recently, multimode transceivers were orders of magnitude less expensive than their single-mode counterparts, making multimode the fiber of choice for many enterprise network designers. Today, the cost of single-mode transceivers has come down significantly, making the increased bandwidth and longer distances made possible by single-mode fiber much more attractive. This presentation covers: Reasons to include single-mode fiber in the enterprise network; What you need as an IT Manager and what is expected as an installer; Choices and recommendations on fiber cabling, connectors, termination and migration options; and Cleaning, testing and maintenance to ensure system longevity and performance.

Managing network connectivity as the fourth utility

When internet connectivity is accepted as a necessary part of building infrastructure, alongside electricity, water, and gas, it is known as the fourth utility. Just like with utilities, the first step in network infrastructure is conducting a physical site survey, and then determining different connectivity options. Utility-grade infrastructure can meet varying requirements for low- or high-bandwidth devices and applications and supports Wi-Fi as a backhaul service.

Webinar: Preparing for 5G Deployment Success

This webinar will focus on how you can prepare for successful commissioning and deployment of 5G in the field and beyond. Whether you work at a service provider, in an enterprise or you are an individual wireless or fiber contractor, we’ll include case studies and tips to make your deployments faster, more accurate and with fewer reworks and repeat visits. Key topics include:Why thoroughly testing at every stage of 5G is the only option; Testing process from antenna to core; and analytics to help service providers plan and optimize.

DWDM basics

  DWDM is an optical multiplex technique. It combines multiple discrete transport channels of different wavelengths and transmit them on a single optic fiber. For example, if we multiplex 32 signals of STM-1 level, then optic fiber capacity will be increased from 2.5Gbps to 80 Gbps.This DWDM tutorial covers basics including DWDM transmitters and receivers and describes optical fiber basics, optical amplifier and other system components.
