Earlier this year Fluke Networks introduced the MicroScanner POE, capable of doing everything the original MicroScanner does but also adds POE testing up to the new 802.3bt 90W standard.
Do you know why the new MicroScanner POE will serve you better than the old MicroScanner? Years ago, someone came up with the idea of combining power and data communications in a twisted pair cable and Power over Ethernet (PoE) was born. In the intervening years, a huge array of devices that source and consume power and data through the same cable have been launched with more coming online all the time. The first PoE standard, 802.3af, was adopted in 2003 and sourced up to 15.4 watts of power over two pairs. Adopted in 2005, 802.3at (also known as “PoE+”) supported up to 30W. Cisco developed their “Universal PoE” UPOE using all four pairs, pushing the maximum power to 60W.
In September 2018, the IEEE approved 802.3bt, pushing the sourced power to 90W. PoE provides substantial cost, efficiency and flexibility benefits, sparking an explosion of powered devices such as cameras, access points, and displays, along with switches to support them. Unfortunately, the term “PoE” is not defined by any standard and a wide variety of standardized and somewhat-standardized implementations are available. Even more confusing, multiple standards, multiple power levels, a variety of non-standardized names such as “PoE+”, “PoE++”, and other designators are used. The result is that it’s difficult even for experts to know what devices will work together. The Ethernet Alliance launched a certification program to end this confusion.
Power levels and requirements are designated by a number from zero to eight indicating the amount (or “class”) of power sourced or required. Technicians need to simply ensure that the class number of the source is equal to or greater than the class of the powered device. When connected to a PoE switch, the MicroScanner PoE will display the maximum power class indicated by the switch, making it easy for the tech to know if the switch and device are compatible. Fluke Networks’ MicroScanner PoE was designed to solve this problem and save the tech hours of frustration. Simply plug the MicroScanner PoE into the cable, and if it’s connected to a PSE, it will display the class (0-8) of power available on the link.
The tech can then compare that to the requirements of the PD and know if the power required will be available. The MicroScanner PoE also provides a complete set of tools for the technician installing PoE and non-PoE devices. Cable wiremapping, a built-in toner, and distance-to-fault indicators can track down cabling problems quickly. When connected to a live switch port, the unit displays the speed of the port up to 10 Gbps, especially useful for troubleshooting slow access points. Cable identifiers can be used to track which cable goes where.

Are network infrastructure manufacturers and distributors doing enough to reduce the amount of plastic used in the packaging of their products? Can working with companies that operate sustainably help installers and integrators win business, and are end users seeking out evidence of environmental credentials when selecting supply chain partners?
As a distributor, our environmental responsibilities and what is achievable is closely coupled to our manufacturing partners, especially regarding packaging and the reduction of plastic. Since it was only relatively recent in our industry that this received widespread coverage, it is to be congratulated that one of the major UK distributors have grasped the nettle of plastic reduction and publicised their achievements. Comms Centre is also making big strides on this, working with our suppliers as part of a much wider initiative on sustainability of which plastic packaging reduction and re-use is just one part. We have a task team selected from across the business reporting directly to the board, looking at the packaging, product staging and end-to-end sustainability including end-of-life disposal. This covers not only packaging but the products themselves which are largely made of plastic, especially cable and how it is managed at end-of-life. It is a major undertaking but in relation to plastic packaging, we estimate that we will soon exceed a realistic goal of a 50% reduction in plastic packaging.
One element of the strategy is our product pre-configuring initiative where we have worked with customers to consolidate and assemble products at our new facility. This not only reduces the time to deploy and waste on site, but enables us to maintain control of re-cycling, ensuring that we reduce all packaging and maximise its re-use. Taking a humble 48 port loaded fibre patch panel, for example, Comms Centre has worked with suppliers to create a rack-ready product and reduced the number of plastic bags from over 50 to just 2. This is just one of many initiatives taking place across all industries. Taken alone it’s not much but collectively we, as an industry can make a significant impact on pollution. Companies need to share their good ideas as it should be seen as a civic duty, not just something to gain a competitive edge.
Whilst single use plastics and their disposal have rightly gained a lot of publicity, it is equally important not to lose sight of other aspects of pollution. The fossil fuel usage and pollutants associated with transport are significant. As a distributor, we can also influence this directly. For example, energy use and CO2 in shipping from a European factory uses significantly less fossil fuel based energy than Far East locations, particularly Sulphur and particulates which are significant in sea transport. (Source: EcoTransIT World.)
Plastic pollutants are one of the most serious threats to our current and future health & wellbeing but strategies that take into consideration all aspects of a sustainable business should be adopted e.g. under the umbrella of ISO14001, the environmental standard. It makes good business sense and ensures that this is embedded into a company’s processes and procedures for the long term.
End users and installers though corporate governance will also play their part and increasingly select products that minimise single use plastic and make the supplier responsible for re-using and re-cycling responsibly.
When you purchase a cut length of fibre cable from your distributor you will likely to be thinking about the basic features you require. Top of the list will be the fundamentals such as transmission performance and compatibility with your optics. This usually comes down to Multimode OM3 / OM4 or single mode OS2 depending on the transmission distance and data speeds required.
Next will come fibre count which will include ‘lit’ circuits and dark fibre for future use. The environmental features will also be important to specify such as sheath type (Internal or external), overall diameter and possibly crush resistance. The bend radius is usually of importance to the specifier. There needs to be flex in the cable to be able to change direction within the confines of the cable containment whether being installed on a cable tray or in an external duct. External cables with PE sheathing or armouring will be significantly less flexible and may need duct pits where they need to be pulled into a duct, terminated or change direction. Tensile strength, if being pulled into ducts will also be a factor to be reviewed.
If the cable is being installed internally, other choices may need to be made such as the flammability rating and construction of the cable. Tight-buffered cable construction tends to be used more frequently for cabling inside buildings because it can be used in both vertical and horizontal cable pathway without additional measures. It can also be easier to prep / terminate than gel-filled loose tube types. However, it is limited in core count usually to 24 fibres and tends to be more expensive than loose tube. Loose tube or Unitube is where the fibres are contained within a semi-rigid plastic gel-filled tube. More recently a dry tube version has been introduced which eliminates messy gel and reduces the weight. Care must be taken with loose tube cable types if installing in the vertical plane e.g. building backbone. Loops will need to be added at intervals (typically every other floor) to avoid the risk of fibres breaking under tension and to prevent the gel from moving. The CPR flammability rating of cables has now precluded the use of universal cables (Internal/external) which were always loose tube type previously.
With so many attributes it goes without saying that there is a wide variety of fibre cables to choose from overall. Distributors generally stock fibre cable in 1km or 2 km drums which are very bulky so they may be selective as to which lines they keep in stock. This means that unless a customer can order a 2km drum and accept a long lead time, there may be no alternative but to select a cable that is not perfectly suited e.g. higher fibre count (and unnecessarily higher cost). In the past, with internal/ external cables this was less of a problem but now that they are not an option, distributors must ideally stock both internal and external cables. Networks Centre has one of the largest selections of LAN fibre cables in stock in the UK so customers can usually order the fibre cable they need without compromise.
With so many variables for a buyer to consider, one could be forgiven for overlooking the physical properties of the bare fibre itself. Whilst fibre is quite forgiving of bending, there can be issues caused by exceeding the specified bend radius e.g. if a cable is kinked. This is called macro bending and introduces unwanted losses. Bend-insensitive and bend tolerant fibre reduces this effect and therefore are more robust for handling and managing. Review of a manufacturer’s specification will reveal the specific type of fibre and whether it is bend insensitive. All Leviton Multimode OM3 and OM4 fibres are Bend Insensitive as standard as specified by IEC 60973. Single Mode OS2 fibre cable is also specified G657.A1 ( ITU-T, the Telecommunications recommendations body) which is Bend Tolerant on their internal Dry Loose Tube CPR compliant cables as standard. Both Bend Tolerant and Bend Insensitive Fibres give far better bending properties than non-bend insensitive types. Importantly, they are also backward compatible with non-bend insensitive fibres.
There are many reasons to choose to buy Leviton fibre cable from Networks Centre. Our extensive stock of 97 different types of fibre cable coupled with the superior specification are just two good reasons. The next time you need fibre cable call Networks Centre. We are fibre specialists and can provide advice to help you make the right choice.
