Network Cabling Pathways for Your Data Center

29 Aug 2019

Used for running and routing cables, network cabling pathways come in various types. Below are the five kinds that are typically used.




  1. Conduits

  2. Fiber troughs

  3. Raceways

  4. Runways

  5. Trays


Conduits


Perhaps the most popular pathway is the cable conduit, commonly used for runs from the wiring closet to work areas. They are made of plastic or metal and come in various sizes to accommodate the type and number of cables utilized. They can be either flexible or rigid for horizontal or backbone cabling.



Fiber Troughs


Fiber troughs come in several capacity options to meet the increasing demand for fiber cabling. Splicing is made simpler and faster through fast splice accessories that come with pre-fitted screws. Cable installation, maintenance, and troubleshooting are also made easier via a tool-less cover removal allowing easy access, and security can be provided by bolting. All-steel construction provides robust cable protection, which can be earthed properly for the elimination of EMI and reduction of attenuation and noise. Steel also has several advantages over plastic, which is typically heavier and needs more supports for long runs. Lighter with greater rigidity, steel decreases deflection and requires 50% less supports, shortening installation times.



Raceways


Raceways make cable installations appear professional and aesthetic. They are often used to conceal cables where it is difficult to install them within walls. Utilized for surface-mounting horizontal cables, raceways are typically assembled using a modular approach. Connectors provided by the manufacturer ensure that a raceway does not exceed the minimum bend radius. They are manufactured from metal, plastic, or rubber. Mounting types include desk, floor, overhead, outdoor, and wall.



Runways


Cable runways are designed for Ethernet and low-voltage cables. They are also called ladder racks because they appear to have rungs like ladders. This design makes them very light in weight and provides complete visibility to the installed cabling, which eases maintenance and troubleshooting.



Trays


Composed of wires, cable trays are used for managing, supporting, and running numerous horizontal runs. They are known for making cable installation, maintenance and troubleshooting easier because of excellent accessibility.

How to Ensure Data Security at the Physical Layer – Part 2

21 Aug 2019

As discussed in Part 1, commercial building networks are becoming increasingly integrated with all aspects of an enterprise, and the physical layer is becoming a bigger target for cybercrime. Part 2 will discuss Recommendations for Implementation in the following topics below.



Monitoring & Detection


AIM (Automated Infrastructure Management) systems are capable of real-time monitoring and mapping of changes to the physical layer, whether they are authorized or unauthorized. Intelligent cabling, patch panels, and connectors enable the automatic detection and recording of changes. IT personnel will also be alerted to unauthorized connections, such as an intruder’s laptop plugged into the company’s network. In addition, AIM and intrusion detection systems can work together to identify and communicate the exact location of an intrusion.



On-Premises Wireless


The WPA2 security protocol of a Wi-Fi system can be exploited because of the unsecured handshake between WPA2 access points, allowing intruders to breach encrypted connections. Fortunately, the more secure WPA3 became more widely available last year. In addition, the Wi-Fi Alliance expects the new and more robust 802.11ax Wi-Fi standard to be released in late 2019.



Security Monitoring


Greater connectivity in smart buildings and facilities will enable networks of IP security cameras and occupancy sensors for the detection of intruders. Well-planned structured cabling infrastructure will allow the installation of these PoE (Power over Ethernet) devices in a multitude of locations, resulting in optimum coverage and enhanced security.



Powered Fiber & PoE


Networks equipped with powered fiber or PoE can utilize switches for providing electricity to connected devices. Typically, their power supply will be backed up by UPS generators and batteries. The centralized nature of this power arrangement provides greater resiliency and security. In the event of a power outage impacting the building or facility, the AIM system and every security device connected will continue working.
