Over the years structured cabling systems have evolved significantly. Recently, the never-ending need for fast data transmission and efficient network performance is only second to the demand for server virtualization, converged data centers, cloud computing, and the advent of high-bandwidth applications like video-on-demand and social media. The predominant demand for high speed data transmission comes from the data center where high-bandwidth is a top requirement for switching, routing and aggregation points for service provider backbones, along with SAN and server interconnections. These drivers dictate keen planning to ensure enterprise networks and data centers are designed and run efficiently. These market dynamics require that IT managers today consider a migration path towards 10/40/100 Gbps Ethernet to meet future network requirements.
On July 16, 2012 the IEEE (Institute Electrical and Electronics Engineers) 802.3 approved the formation of a study group to develop objectives for the Next Generation Base-T (NGBase-T) application over balanced twisted pair cabling. The intent of the study group is to explore technical feasibility and market potential for speeds higher than 10Gb/sec over twisted pair cabling. Copper based twisted pair cabling continues to be the most popular media used for Ethernet networks.
This article highlights considerations that led to the decision to approve the IEEE study group for NGBase-T.
If we look at structured cabling system markets today we find a number of categories being used and offered by vendors. Although Category 5 products are no longer available for sale there are still customers using it in their premises. Category 5e, is a commodity product all over the world including emerging markets. Cat 6 is often a first choice for new cabling system installation across most continents with C6A as the next choice. There are higher category products available (cat 7 and C7A) but these, due to high cost, accounts for only a small percent of total sales. C6 and Cat 6A systems are the two most considered SCS by customers as first choice products, and the purpose of this document is to help businesses reach an objective decision as to which SCS to implement.
Business initiatives demand that IT look beyond supporting infrastructure, devices, and applications on the network to managing the services that are supported by these components. Additionally, this must be accomplished in an environment of optimizing costs and resources. This article discusses how the demand for IT Best-Practice Standards to achieve a more holistic view of the physical components can be fully enabled using Next Generation Intelligent Systems.
The Physical Layer, Layer 1 of the OSI model, is fundamental to the existence of any business yet ironically still often the most overlooked aspect when it comes to identifying crucial cost savings opportunities and improved efficiency targets. As both private and public organisations face flat budgets or even budget cuts within IT we are seeing more back to basics approaches to try and squeeze more out of existing infrastructures. This article discusses how advanced Physical Layer technology can work towards identifying and resolving these critical aspects within an organisation.
Installation of a cabling system in healthcare facilities involves consideration of many factors. The healthcare field provides one of the most demanding environments for a structured cabling system. Facilities are designed to operate for 50 years or longer. Adoption of 10GBase-T Ethernet is rapidly increasing and is expected to be the standard for the foreseeable future in healthcare facilities.
This article discusses the best solution for the modern day healthcare facilty.
Every element of a Physical Layer One Network infrastructure goes through a lifecycle from planning, design, installation, maintenance and ultimately, retirement. The concept of ‘Lifecycle Management’ ‘ is not new to the world of IT but it is a new concept to apply ‘Advanced Physcial Layer Lifecycle Management’ (APLLM) principals to structured cabling. Cabling infrastructure is all too often considered a necessary evil, a burden on pathways and spaces, a limiting factor in implementing change, and according to some industry experts a not so infrequent source of network outages. Along with power, cooling and weight, cabling infrastructure was also recently classified as one of the four biggest challenges facing data centres today by Ron Hughes of the California Data Center Design Group.
The need to deliver more user-friendly cabling networks has led to a change in the infrastructure model for structured cabling systems. This white paper examines some of the issues involved with the new architecture and provides guidance on design and testing of such systems to facilitate successful implementation.
It is a widely accepted statistic that 70% of LAN failure is attributed to cabling**. This does not mean organizations are purchasing faulty systems, on the contrary, modern cabling is a stable system which seldom fails and is backed in most cases by comprehensive long term 25 year warranties. Network failures attributed to cabling are effectively management failings in the form of poor control and documentation practices that must be addressed.
Linking commercial and residential buildings, college campuses and municipal buildings with high bandwidth trunks is as essential as it can be challenging. This article will focus on Free Space Optics (FSO), a bi-directional, point-to-point optical beam wireless technology that is an attractive, robust, and affordable high bandwidth option for true broadband campus connectivity.
