Understanding TSN? Understand Its Role in Future Ethernet Networks

Following new trends and technologies, you’ve possibly been hearing a lot about time sensitive networking (TSN). It’s a relatively new technology, have you been wondering, “what is TSN?” and “why does it concern my company?”

As you may have read in this previous post about TSN, this new technology transforms standard Ethernet from an “I’ll get it there as soon as I can” communications technology to one that provides timing assurance for mission-critical applications. Now, you can achieve an entirely new level of determinism in IEEE 802.1 and IEEE 802.3 Ethernet networks.

3 Ways Data Centers Can Use CFD Modeling

You might of heard about computational fluid dynamics (CFD) modeling when it comes to the design of high-performance Formula 1 racecars. By using CFD modeling to maximize down-flow forces while minimizing friction – for the racecar body and smaller “wings and struts” – Formula 1 produces a winning combination.

In a similar manner, CFD can be utilised in today’s data centers during design, capacity planning, troubleshooting and day-to-day operations. It can be used to properly develop the best design and operations solutions throughout the entire data center ecosystem, from the micro environment (chips) to enclosure environments (cabinets and containment) to the macro environment (computer white space and the entire data center hall).

Here are three ways in which your data center ecosystem can benefit from CFD.

Minimize Complexity with Port Monitoring: A substitute to Port Replication

IT managers frequently face new challenges as they have no choice but to migrate to next-generation, faster networking infrastructure.

Managing fiber infrastructure has become a mundane undertaking as fiber counts increase. Connectivity agility needs to be brought about from Day One to support future network reconfiguration and upgrade cycles.

 

What is Port Replication?

In many mission-critical applications, a backup link is required in addition to the primary link to ensure high service availability.

Port replication on active networking gear can provide highly reliable networking service that allows fast troubleshooting for connection issues and minimizes system downtime. In this scenario, the system has 100% redundancy; server and switch port usage is reduced to 50%. Additional cable and floor space can add to overall system costs.

Reduce Alien Crosstalk: Differential Mode and Common Mode Signals

If you have been perusing our blog for some time, then it’s no mystery to you: Many components make up the infrastructure that supports your network – from cables to connectors – and they all have to follow relevant standards, be well designed and be properly installed in order for your network to function like you need it to.

Cable imbalance, which can lower immunity to interference – can increase alien crosstalk between adjacent cables to levels that are beyond recommendations, negatively impacting network performance. Every component of a cabling system has the potential to effect alien crosstalk performance and compromise cabling system quality. The cables and how they are connected can have a major impact on data transmission. It’s one of several reasons why it is crucial to use the appropriate cables and connectors.

Bending Loss – The Risks of Reusing Installed Fiber Cable

Due to its ultra-high data transmission capacity, ultra-low loss and installation flexibility, glass optical fiber is the most engery-efficient data transmission media available today. Optical fiber cables have been distributed worldwide to connect people and “things” together.

Stated by CRU’s Optical Fibre and Cable Monitor, last year, the global optical cable demand reached 318 million kilometers in the first three quarters of 2016.

As we mentioned in a previous blog, two types of optical fiber are available for different network environments and link distances:

  • Multimode fiber (MMF) for short-reach links up to a few hundred meters, typically used in data centers environments
  • Singlemode fiber (SMF) for long-reach links, such as in LANs, access networks, metro/transport networks and hyperscale data centers

JAYCOR Celebrates 30 Years in Business

JAYCOR Celebrates 30 Years in Business!

From humble beginnings and a family tradition, JAYCOR has over the years grown into a dynamic and multi-faceted connectivity solutions provider, representing world-leading brands in the cables, connectors, network infrastructure and allied industries.

Humble beginnings

JAYCOR founder, Jeff Pokroy, grew up with the cable business in his blood, from Saturday mornings as a young boy licking stamps at his father Simon’s cable business that dated back to 1954, to formally joining the business in 1974.  After the business was sold to a large corporate, Jeff left to start his own business, JAYCOR International, in April 1987.  Operating without much capital, Jeff relied on the support of long-standing, loyal suppliers who placed stock on consignment to help JAYCOR out of the starting gates. The company now features an extensive customer base, world-leading suppliers, deep expertise, and a commitment and passion for the industry from second and third generation family members as well as top-notch independent professional management.

Times change

JAYCOR started as a traditional cable distributor, however, as technology changed, so did the business.   JAYCOR diversified its portfolio of products and value added services across a number of verticals and now takes pride in having become a multi-faceted connectivity solutions provider of specialized and often application-specific cables, connectors, network infrastructure and allied connectivity products and services.

In 2000 JAYCOR became the Sub-Saharan Africa distributors for Belden  Cables, a global leader in cable manufacture, and in 2008 exclusive distributor for LEMO, a world leader in connector technology and manufacture.  JAYCOR remains a strong proponent of local manufacture and suppliers alike, offering an extensive range and various options to best suit the needs of its customers.

Over the past three decades JAYCOR has witnessed globalization and the enormous step-change in the evolution of technology and the impact it has had on businesses and consumers. And within that change, connecting technology has provided the essential pillars to support an interconnected world, through the Internet of Things (IoT) and the Industrial Internet of Things (IIoT). Today’s cabling and connector technologies are pivotal to the advancements of big data, renewable energy, automation and the many other mission critical technologies that shape our present and future.

Cable Plugs Matter More than One Thinks

The wireless access points, cameras and alternative devices being mounted on our ceilings or high up on walls are connecting to our networks – but not all use standard faceplate, jack and patch-cord configurations to do so. Instead, a direct-attachment system is being used, which terminates horizontal cable with a field cable plug that plugs directly into devices.

There are two cable plug options for Category 5e, Category 6 and Category 6A twisted-pair cabling:

  1. Crimp-on plug types
  2. PCB plug types

Crimp-on plug types require preciseness; cabling wires, contacts and plug components must correspond correctly to achieve appropriate electrical performance. A crimp-on plug must be designed for each cable’s geometric differences. A PCB cable plug, for that matter, does not take cabling configuration into account. Installing a PCB cable plug is just like putting on a jack: You terminate the cable onto IDCs and place the plug housing on top. This disassociates the characteristics of the cable and plug when connecting them.

Attaining Wireless via DAS Networks for IoT

While attending an industry conference on Internet of Things (IoT), I came across a comment made by a panelist. A numver of them compared and contrasted the competitive landscape from various perspectives (commercial, industrial, residential and utilities), but one popped up when he spoke about the importance of focusing on infrastructure.

The panelist advised us about the nature of the sometimes-uncertain and/or shifting infrastructure capabilities of platforms, devices and software we rely on. Infrastructure is recommended for communication and a functional IoT. Further, he went on to advise that more awareness should be paid to infrastructure to hinder IoT growth from being impeded because our “things” can not communicate with each other.
