Are you Ready for 40G and 100G?
Core and edge higher-speed Ethernet equipment from Cisco, Force10, Brocade, and numerous other vendors is on the market today; by 2015, 25% of network equipment ports are projected to be 40G and 100G. Create a simple, cost-effective migration path by installing a structured cabling system that can support your future 40/100G networking needs. (Leviton) |

An Overview of Macrobending and Microbending of Optical Fibers
Bending can increase the attenuation of an optical fiber by two mechanisms: macrobending and microbending. Some bending is of course unavoidable, e.g., shipping and storage, optical cable manufacturing and installation as well as fiber termination and deployment. Understanding the fundamental nature of attenuation increase with bending enables development of products and usage conditions to maintain the initial superior attenuation of fiber. |

Designing a Reliable Cabling Infrastructure for Healthcare Facilities
Hospitals and other medical facilities face daunting new IT challenges as every facet of care increasingly relies on networked electronics. Berk-Tek and Legrand | Ortronics highlight key trends and opportunities to address these changes through structured cabling best practices. (Berk-Tek, a Nexans Company) |

Structured Cabling Verification to Vendor Specifications: Marketing Hype or Better for Your Network?
Many structured cabling vendors submit their products to third-party verification programs that perform testing to TIA-568. Some go a step further and have independent verification to their own specifications that are commonly better than the minimum requirements from TIA. This paper will explain why this is important and how this will affect your network. The difference between channel and component testing and why you need both will also be discussed.

RoHS/WEEE Overview and Recommendations
The increasing global awareness of the impact that products and the manufacturing processes used to make them has on the ecology has prompted efforts to control and ameliorate this impact. There have been efforts that focus on pursuing consensus to reduce both emissions and material consumption. Other efforts have been targeted at improving processes with the goal of reducing global repercussions. Recently, the European Union has implemented a set of requirements for a specific family of products and materials. The intent is to reduce and eventually eliminate their future ecological impact. These requirements, colloquially known as RoHS and WEEE, have been referenced or adopted into the legislation of many nations that are moving toward increased ecological responsiveness. Increasingly, this means that compliance to the requirements of RoHS and/or WEEE may well be mandated outside of the European Union in the near future. (Berk-Tek, a Nexans Company) |

Field Testing Installed Optical Fiber Cabling
This joint white paper prepared by Legrand | Ortronics and Fluke Networks reviews best practices for the technician performing field tests on installed optical fiber cabling. As traffic over networks expands and expectations of reliability increase, testing optical fiber cabling after installation is more important than ever before to assure the end-user that the installation was done properly and that the cabling will support Local Area Networks (LAN) into the future.

Encircled Flux ? The New Standard in Multimode Testing Accuracy
Have you ever tested a multimode fiber optic link with light sources from two different equipment vendors? By simply using a different light source you may notice that the loss measurement is different by as much as 50%! Ever wonder why this happens? Without proper controls, multimode light sources will inject light into multimode fiber over variable paths, or “modes”. “Modal power distribution” is a way of explaining how many modes are supported by a multimode fiber; typically, multimode fiber supports hundreds of modes while a singlemode fiber supports one mode. This modal power distribution is commonly referred to as a “launch condition”. When light sources operate under different launch conditions, link-loss measurements will vary proportionately, resulting in different and confusing test results.

Fiber Best Practice: Fiber Plant Characterization and Troubleshooting (Tier 2 Certification)
The Fiber Best Practice Series was designed by Fluke Networks to educate about important optical fiber best practices, including:
(Tier 2 certification) This white paper details the best practice of loss-length (tier 1) fiber certification. With 40 G/100 G infrastructure deployments in the datacenter becoming reality, the shrinking loss budgets of optical fiber cabling due to increasing bandwidth demands mean that reliable and efficient initial installations are now more important than ever. To minimize costly installer/contractor callbacks, network technician troubleshooting time, and unnecessary network downtimes, fiber-handling best practices should always be followed.
