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 ...

There Is No Universal Winner Between 200G and 400G 200G and 400G Ethernet serve different roles in data center networks. The right choice depends on the workload, topology, installed base, traffic profile, available fibre, port density, power and cooling envelope, host-platform support, budget, and ...

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...

PAM4 Is a Signalling Method, Not a Complete Link Design PAM4, short for four-level pulse-amplitude modulation, represents information by using four signal levels. In an ideal mapping, each symbol can represent two bits of information. This makes PAM4 an important technique in higher-rate electrical ...

25G SFP28 AOCs in context A 25G SFP28 active optical cable (AOC) is a direct-attach fiber assembly with SFP28 connectors permanently fitted to both ends. It is often a practical choice for short-reach 25GbE Ethernet links between servers, top-of-rack switches, and neighboring racks. An AOC is a comp...

Why 25GbE planning starts with the workload 25 Gigabit Ethernet is a single-lane Ethernet technology used widely for server access, storage connectivity, and high-performance computing networks. IEEE’s 25 Gb/s Ethernet task force completed its work with the approval of IEEE Std 802.3by-2016, and lat...

What OM5 wideband multimode fiber is designed to do OM5 is a 50/125 µm wideband multimode-fiber category developed for short-wavelength wavelength-division multiplexing (SWDM) applications. It extends specified effective modal bandwidth beyond the traditional 850 nm point used by earlier multimode c...

What a 400G QSFP-DD DAC Is Designed For A 400G QSFP-DD direct-attach copper cable, often called a DAC, provides a fixed copper connection between compatible high-speed ports. It is commonly considered for short-reach interconnects within a rack or between nearby racks because it removes the need for...
