Network Resilience Is a Service Discipline Modern organisations depend on networks that extend beyond a single office or data center. Customer services, cloud applications, identity systems, remote users, suppliers, DNS, internet providers, collaboration platforms, and security tools can all be part...

5G core network revenues are pushing towards US$1 billion in revenue in 2020, propelled by strong investment and growth in 5G networks. According to Dell’Oro Group’s Mobile Core Network Quarterly Report, service providers are ramping up their 5G Core market deployments – a trend that is expected to ...

Data storage demands these days continue to escalate at a rapid pace, as the global spread of the Internet and the digitization has disrupted the lives of people. According to a report, there would be around 40 zettabytes of data in the world this year. And by 2025, it’s predicted that the global da...

25G SFP28 Transceivers for Data Center and Enterprise Applications   With the rapid expansion of data centers, faster speed and higher bandwidth are required for better experience. To meet the demands, data center operators are now turning to 25G Ethernet technology. 25G SFP28 transceivers, as ...

Why Supplier Due Diligence Matters Enterprise hardware and infrastructure projects depend on more than the technical specification of a single item. The supplier relationship affects availability, compatibility, documentation, support, logistics, warranty handling, replacement strategy, and the abil...

What a Tunable DWDM SFP+ Module Does A tunable DWDM SFP+ module is an optical transceiver designed to operate on a selectable dense wavelength-division multiplexing channel within its supported tuning range. Instead of stocking a separate fixed-wavelength module for every approved channel, an operat...

Data-center cabling is an operating system for the physical layer As a data center grows, cabling stops being a simple connection task. The physical layer must support servers, switches, storage, management systems, monitoring, security, power-related controls, and planned migrations without creatin...

On September 4-7, 2019, the 21st China International Optoelectronic Exposition will be held in Shenzhen Convention and Exhibition Center. The exhibition covers optical communication, laser, infrared, precision optics, optoelectronic innovation, military-civilian integration, photoelectric sensing, d...

OM5 migration is an application decision, not a default upgrade OM5 wideband multimode fiber is intended to support short-wavelength wavelength-division multiplexing (SWDM) applications over a specified wavelength range beyond the traditional 850 nm reference point. That capability can be valuable i...

DWDM SFP+ deployment is a system-design task A tunable DWDM SFP+ module can reduce the number of wavelength-specific spare units required for a compatible 10G optical network, but it does not turn every SFP+ port and dark-fiber pair into a ready-to-use DWDM link. A successful deployment depends on t...

What a pluggable optical transceiver does A pluggable optical transceiver is the physical-layer device that connects electrical signals in a switch, router, server, or storage platform to an optical-fiber link. At a high level, it converts electrical signals from the host into modulated light for tr...

Infrastructure Priorities Begin with the Workload Data center infrastructure decisions should begin with the workloads and services the environment must support. Cloud applications, enterprise systems, analytics, AI workloads, storage platforms, collaboration services, and network functions can have...
