Future-Proofing with Cat6a

August 8, 2019 at 8:00 AM

 

There is no telling what technological breakthroughs await us in the future. But one thing no one wants, is to have to re-cable an entire network because the existing cabling can’t meet the speed and bandwidth needed to support future technology. Re-cabling consumes time, money and a lot of resources. So what is one to do to future-proof their cabling? For many, Cat6a is the answer.

 

Cat6a cables are high-tech cables with advanced performance standards for twisted pair cable systems that offer features surpassing other category cables. They offer more power, faster speeds, tighter twists, further distances, better shielding and greater assurance that they’ll be able to keep up with today’s technology and future advancements. Cat6a cables are able to support upcoming advances in technologies such as Power over Ethernet (PoE), bandwidth-intensive applications and data transfers up to 10 Gbps. With 23-gauge twisted pair, they can transmit those 10 Gbps speeds over distances of up to 100m. Cat6a cables also feature shielding to control interference and crosstalk, which improves performance and increases operational bandwidth. While the extra shielding might add bulk to the cabling, the benefits of Cat6a far outweigh the increased costs that go along with a heavier cable.

 

In addition to PoE, there is a long list of technology coming to market that will continue to increase the need for speed and power. For example, next generation Wave 2 Wi-Fi devices will require 4 Gbps speeds in the near future. Enterprise businesses upgrading to this technology will be able to count on Cat6a to provide the speeds needed. HDBaseT is another emerging technology that would require Cat6a capabilities to transmit full, high definition video, audio and data files over 100 meters. Plus, Cat6a cables can manage the data load needed to support IP convergence, which is beneficial to enterprise networking applications.

 

Overall, Cat6a might cost a bit more than Cat5e or Cat6, but investing in Cat6a now and its ability to keep up with the changing demands of new technology will save money in the long run. Check out our extensive selection of Cat6a cable assemblies.

802.3bu - Power Over Data Lines (PoDL)

October 25, 2018 at 8:00 AM

 

In the realm of IEEE standards, 802.3 has some pretty good tricks up its sleeve. There is 802.3bt which expanded the capabilities of Power over Ethernet (PoE), 802.3bv brought you Power over Plastic Optical Fiber (POF) and 802.3bz which delivers 2.5 Gbps and 5 Gbps speeds data over copper. Now, the IEEE has unveiled 802.3bu – a standard for Power over Data Lines (PoDL).

 

Initially, single-pair Ethernet was created to help meet a demand in the automotive industry for Ethernet connectivity in vehicles. 802.3bu defines the specifications and standards for delivering power over single twisted-pair to connect Data Terminal Equipment (DTE) with IEEE 803.2 interfaces. This standard also extends the wattage range to up to 60 Watts of power, which is more power over a single cable than the PoE standards 802.3af and 803.2bt. With this PoDL standard, the most recent physical layers of single twisted-pair Ethernet are supported, including 100BASE-T1 and 1000BASE-T1, while using unshielded twisted-pair cables. This results in a lower cost and lighter weight solution, which is always good news. It is targeted for use in automotive, industrial automation, air and rail transportation, and other applications that use 100BASE-T1, 1000BASE-T1 or any single-pair data or non-data entity protocol. The IEEE 802.3bu standard also opens itself up for the possibility of additional applications across a variety of industries in need of solutions to adapt to the Internet of Things (IoT) expansion.

 

The goal of the 802.3bu standard is to specify a power distribution technique for use over a single twisted-pair cable that will allow for operation if data is not present. This standard is designed to deliver power that supports multiple voltages and classes of power at each voltage level. Plus, it has the capability of fault protection and detection to identify device signatures and communicate directly with devices to ensure precise and safe power delivery. PoDL supports fast startup operation with predetermined voltage configurations and the option of operation with run-time voltage configuration. It ensures compatibility with the IEEE 802.3bp standard. However, it is not compatible with Ethernet applications that operate over 2 or 4-pairs of twisted-pair cable.

 

With the introduction of 802.3bu PoDL, not only is the wattage delivery increased and intuitive, the possibilities of power delivery are increased as well.

Next Generation PoE - What You Need to Know

August 23, 2018 at 8:00 AM

 
What’s better than Power over Ethernet? More Power over Ethernet (PoE), of course – and that is exactly what PoE++ is delivering. PoE++ expands upon the traditional PoE benefits of delivering data and power over a single Ethernet cable, it increases power capabilities and extends PoE’s reach into new industries and applications. Here, we’ll tell you exactly what gives PoE++ those two extras plus signs.
 
First, let’s look at a numbers comparison. The first ratified PoE standard 802.3af supports 15.44 watts of power, but power dissipation usually lowers that number to a reliable 12.95 watts. Then PoE+ was introduced and bolstered power to 30.8 watts with the 802.3at standard, though power dissipation usually takes its toll and lowers power to 25.5 watts. PoE++ (the 802.3bt standard) will be capable of supplying more than 3 times the power of PoE+ with up to 100 watts (Type 4) of DC power and the ability to support 10 Gbps connections.
 
Traditionally, PoE has been used in networking applications. With PoE++, the technology’s reach is extended to include healthcare, point of sale, financial and surveillance industry applications. PoE++ utilizes all four twisted pairs of an Ethernet cable for optimal power transmission. It consists of Mode A and Mode B, and combines them to reach higher voltage levels. Mode A is also referred to as Type A, Type 3 or 4-pair PoE. It is specified for 60W, 50W reliable, and is able to support technology such as access controls, point of sale readers, IP cameras and nurse call devices. Mode B is also known as Type B, Type 4 or higher-power PoE. It is designed for 100 watts of power, 80 watts after power dissipation, and increases the capabilities to also include support of videoconferencing systems, laptops, desktops and televisions.
 
PoE++ is slated to bring more power, more conveniently to more devices than ever before. With all of the speed, convenience and capabilities that this new technology offers, it’s no wonder that PoE++ earned those extra plus marks.
