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.

Inclusive prosperity

JAYCOR is a proudly South African business and is deeply committed to B-BBEE, economic growth, social and skills development and the people of Africa’s transformation for the prosperity of all. We have for many years been supporters of communities and families inside and outside of our organisation and are currently engaged in an exciting process to promote inclusive ownership in JAYCOR. Our family is becoming bigger and more diverse.

Celebrating three decades

It is with immense pride that JAYCOR celebrates three decades in business and we thank and acknowledge all our staff and stakeholders who have been a part of the journey. The goal is to support and deliver innovation and transformation across the continent into the next 30 years and beyond.

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.

Are Category Cables Sufficient for HDBaseT?

New discoveries have been made about HDBaseT™ signals over the past couple of years, impacting the types of cables that are best suited to transport these new signals.

Recent test results indicate, category cables – which are optimized for Ethernet traffic – often battle with the HDBaseT signal. The characteristics of category cables are often overkill for HDBaseT applications; other times, category cable characteristics are not sufficient to guarantee a great signal. HDBaseT is a dissimilar type of signal, and 4K video is jolting that threshold even further.

To better understand the capabilities of category cables when it comes to HDBaseT, we want to share the outcome of Belden’s in-house cable testing. But, first, it’s vital  to know what standard we tested to.

Switching to M12 L-coded Power Connectors and what it Signifies for You

As multiple factory machines are connected through the Industrial Internet of Things (IIoT), companies could soon bolt into a major problem. have you felt this shift: the promise of refined productivity from these connected machines producing more data demands additional power and space on your factory floor.

That is why the M12 L-coded Power Connectors have been selected by the PROFINET User Organization as the new standard for 24-volt power supply systems used in PROFINET devices. In the current PROFINET guideline “PROFINET Cabling and Interconnection Technology,” two round connectors with screw connections are specified for the 24-volt power supply, in addition to a push-pull rectangular connector.

This new guideline, scheduled for publication in April 2017, will replace these two variants with the L-coded M12 Power Connectors.  M12 L-coded Power Connectors are an extension of the current IEC standards. The most important thing  about these connectors is that they are smaller than the common market-standard of 7/8”, while delivering more power.
