Help! My Copper Cabling Link Failed
You’ve just finished a copper cabling installation for a customer, your DSX-5000 CableAnalyzer is properly configured and you’re ready to start testing. With a press of the “TEST” button, you’re off and running.
Link after link, the tester displays a “Pass” and you’re feeling really good about the quality workmanship of your installation.

Angriff der Drohnen - Teil 1
Im Februar haben wir überlegt, ob 2015 das Jahr der Drohnen würde:
Sechs Monate später scheint die Antwort ein klares „Ja“zu sein. Fast-Zusammenstöße zwischen Verkehrsflugzeugen und ferngesteuerten Drohnen machen mit einer alarmierenden Rate weiterhin Schlagzeilen.

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.
