Fluke Networks honored by Cabling Installation & Maintenance 2015 Innovators Awards Program
Last week at the opening of the BICSI Conference in Las Vegas, the editors of Cabling Business Magazine announced that Versiv and LinkWare Live have each won the Cabling Installation and Maintenance Innovator’s Award. These awards recognize the most innovative projects and products in the structured cabling industry. The judging panel consisted of cabling and communications system specifiers, designers, integrators and managers with vast professional experience.

Attack of the Drones - Part 1
In February, we pondered whether 2015 would be the year of the drones:
Six months later, the answer appears to be a resounding “yes.” Near-miss encounters between commercial aircraft and remote-controlled drones continue to make headlines at an alarming rate.

Tier 1 Testing using an OTDR on Installed Fiber Cabling?
The Telecommunications Industry Association (TIA) is committed, by formal consensus, to develop standards for the benefit of industry and is represented by hundreds of companies. While participating companies cooperate to develop standards, each have their commercial business interests to protect. Sometimes, these companies over-reach to meet their business goals. Fortunately, the TIA voting and balloting process works well as a means to check and balance sometimes rogue proposals.

Testing Installed Fiber Cabling Terminated with MPO Connectors
Several published standards describe how to perform attenuation measurements on installed fiber optic cabling. However, no standard exists that provides guidance for testing installed fiber optic cabling terminated with MPO connectors. Currently, a technical report (TR) is being drafted that provides such testing guidance.

What You Need to Know About Testing BIMMF
Developed for use in data centers and enterprise network applications with a very tight loss budget, bend insensitive multimode fiber (BIMMF) is able to withstand tighter bends with substantially less signal loss than non-BIMMF.
A BIMMF design tightly confines the higher-order modes that are more likely to escape the fiber core during bending. The design achieves this by adding a specially engineered optical “trench” between the fiber core and cladding.

HOML as a Source Qualification Test
TIA adopted IEC 61280-4-1, the standard defining attenuation measurements of installed multimode fiber cabling, as ANSI/TIA 526-14-C.
In IEC 61280-4-1, the encircled flux launch is defined as normative (required) for these cases and there is no intention to change requirements in the next edition:
Case 1 - 50 μm core fiber at 850 nm,
Case 2 - 50 μm core fiber at 1300 nm,
Case 3 - 62.5 μm core fiber at 850 nm,
Case 4 - 62.5 μm core fiber at 1300 nm.

Revision to IEC 61280-4-1 Ed 2.0, Fibre-optic communication subsystem test procedure – Part 4-1: Installed cable plant – Multimode attenuation measurement
This primary international standard provides guidance for measurement of attenuation using power meters, light sources and OTDRs on 50/125 µm and 62.5 µm multimode fiber cabling that may include connectors, adapters and splices. Various test methods and cabling configurations are described. This report gives important information regarding upcoming changes for anyone needing to specify testing. Architects, Consultants and Engineers may use this information to learn of changes in IEC, anticipate customer concerns and gain insight to cabling testing trends.

Standards Update: The Four A’s of Harmonization
With ANSI/TIA being a North American standards body and ISO/IEC considered international, some often question why we need both, especially considering the similarities between the two.
But there are also plenty of differences—from terminology and spelling, to policy and codes. The good news is that with technology having made our world a much smaller place, TIA and IEC are fast at work harmonizing standards.
