Attack of the Drones - Part 2
When speaking of drone attacks, most people think first about risky encounters between remote-controlled drones and commercial aircraft (/node/215376) or drones used for malicious airborne snooping and pen-testing (/node/175608). However, businesses exploring commercial drone applications face a completely different challenge: keeping those remote-controlled business drones safe.
Earlier this month at DEFCON, attendees learned about two new drone attacks.

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.

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.
