LAN Cabling: Going Beyond Standards to Improve Capacity

Blog Category: , , by

Cabling standards exist for a purpose – it assists you get the most out of your networks. Many cabling solutions are designed to execute beyond what the standards specify.

When standards for performance are set by groups like the Telecommunications Industry Association (TIA), the International Organization for Standardization (ISO/IEC) and the Institute of Electrical and Electronics Engineers (IEEE), why go beyond what they advise? Because cable performance which moves beyond standards can lead to a more reliable LAN connection for enterprises.

Bandwidth and Information Capacity

The standards spell out specifications for insertion loss and background noise levels (return loss, near-end crosstalk [NEXT], etc.). If the cable stays within the recommended parameters, the cabling system will function as intended in terms of signal to noise ratio, or information capacity.  For cabling, this is referred to as bandwidth.

How to Earn LEED Materials & Resources Points for Green Buildings

Blog Category: , , , by

LEED (Leadership in Energy and Environmental Design) is an ecology-oriented building certification program run under the auspices of the U.S. Green Building Council (USGBC)

When LEED v4 was launched in 2013, many changes came along with it. One of the major adjustments, in our opinion, has to do with an overhaul of the LEED Materials & Resources credits.

LEED v3 called on project crews to source building products based on a percentage of the total cost of materials that made up the LEED building project. It focused exclusively on single product attributes (such as recycled content) and materials costs.

LEED v4 instead places urgency on the importance of product lifecycle and transparency of product ingredients. LEED Materials & Resources credits now encourage project teams to invest in products and materials that disclose lifecycle information, track environmental impacts of products and reveal the chemical ingredients used in the product. Not only does this switch to the LEED Materials & Resources credits encourage project teams to spend time seeking out environmentally responsible products, but it also benefit manufacturers that produce products with improved (and verified) lifecycle impacts.

 

How to Earn LEED Materials & Resources Points

To gain points in the LEED Materials & Resources category, project teams will need to source 20 qualifying products sourced from five different qualifying manufacturers. These manufacturers, and the products they produce, that have environmental product declarations (EPDs) and either health product declarations (HPDs) or material health assessments (MHAs) can contribute to LEED points.

Even if you’re not currently pursuing a LEED project, paying attention to the building products you use – including cable – offers benefits. Products that can offer LEED Materials & Resources credits ensure that:

  • Products and materials have known hazards revealed
  • Products and materials have undergone processes to document their lifecycle and environmental impacts

2017 And Digital Buildings

What is a Digital Building?

A digital building is seamless in operation, thanks to its connected infrastructure. Building systems that have stood alone for years using a combination of twisted-pair cabling, AC power and video cable – voice, data, wireless, lighting, security, AV, etc. – can now be networked together using one common infrastructure. All of these devices, which use Internet protocol (IP) to send and receive data via the network, converge under one umbrella for cost savings, easier maintenance and better building control.

4 Ways to Reinforce Your Network with Digital Infrastructure

Blog Category: , , by

We have proclaimed 2017 to be “the year of the digital building.” A digital building operates its network to connect previously standalone building systems together using one common, connected digital infrastructure. Through Internet protocol (IP), these devices can send and receive data via the network.

Can we support this ubiquitous LAN (a phrase we coined in 2016 to describe bringing traditionally separate, standalone building systems together under one network) with our digital infrastructure? We’ve mentioned before that your digital infrastructure will make or break your network. The best, most high-performing building systems designed to connect via IP and transmit/receive data won’t do you any good if your digital infrastructure can not provide reliable uptime and fast speeds for data sharing and consumption.

The Advantages of High-Quality, Low-Loss Fiber Connectivity

Blog Category: , , , , by

Data centers and LANs are migrating effortlessly from 10G to 40G and 100G Ethernet to provide scalability and accommodate more bandwidth as future applications become reality; meanwhile, the imminent deployment requirements of next-generation 200G and 400G Ethernet speeds are already in range, mainly driven by cloud data centers and the wireless 5G ecosystem.

In previous blogs, we’ve discussed the differences between singlemode and multimode transceivers, and the differences between “fiber link budget” and “channel insertion loss” as they relate to this migration. When it comes to actual deployment, however, it’s crucial to note that a high-quality, low-loss fiber solution makes all the difference when it comes to reducing risk, avoiding performance errors and minimizing total cost of ownership.

Understanding TSN? Understand Its Role in Future Ethernet Networks

Blog Category: , , by

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.

Reduce Alien Crosstalk: Differential Mode and Common Mode Signals

Blog Category: by

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.

Cable Plugs Matter More than One Thinks

Blog Category: , , by

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.

Next-Gen Ethernet for LAN

Blog Category: , by

Around the past 36 years, Ethernet has become the most embraced and widely distributed protocol in our global network infrastructures. Fixed Ethernet connections offer secure, fast, stable and consistent speeds, and easily support the download of large files or high levels of content streaming.

Case in point: Last year, specified by Dell’Oro research, Ethernet switch shipment counts were at 484 million. High-end Ethernet router port shipment counts were at 5.9 million. What is powerinf this phenomenal momentum? Broad market acceptance and the diverse list of applications that Ethernet supports.
