Using a few LEDs and really cheap fiber optics, I made this dead sexy, illuminated fiber optic rose.
Fiber Optics. They’re not just for humans anymore. When GeekBrief.tv star Cali Lewis visited the My Home 2.0 Lair, Techno-Guru Alison made electronic fashion for a podcaster’s best friend.

Great gift for all kinds of celebrations, including Christmas Day, Halloween, etc. This blinking Fiber Optic Wand with plastic handle can be used in the night for fairy/enchanted themes. Powered by 3 AG13 batteries which are included.
By twisting fiber optic strands into helical shapes, researchers have created unique structures that can precisely filter, polarize or scatter light. Compatible with standard fiber optic lines, these hair-like structures may replace bulky components in sensors, gyroscopes and other devices.
While researchers are still probing the unusual properties of the new fibers, tests show the strands impart a chiral, or "handed," character to light by polarizing photons according to certain physical properties.
In conventional optical fibers, light is transmitted from one end to the other through a round core housed within a concentric outer cladding. But, because a circular core does not develop handedness when twisted, the research team wound rectangular-core fibers to create a double helix.
When the team tested the twisted fiber, they discovered that some photons left the core and entered the cladding. Photons with the same handedness as the fiber entered the cladding whereas photons with handedness opposite that of the fiber remained in the core.
This research was funded both NSF and the National Institute of Standards and Technology Advanced Technology Program.

“Cuba’s Internet connectivity is speeding into the future thanks to a 995-mile long fiber optic cable from Venezuela. The $70 million cable project, expected to be fully operational by July, will give Cuba a data transmission speed of 640 gigabytes...”
Cuba is getting an underwater high-speed fiber optic cable connecting it to Venezuela. The cable will make Internet access in the country 3,000 times faster. But according to the BBC, not everyone will get access.
“Access is restricted and available only with government permission - although since 2009 Cubans have been able to use Internet cafes, mostly in hotels, and there is a strong black market for Internet connections.”
The BBC also reports officials in Cuba have blamed its slow connection on the U.S. trade embargo. Many media outlets are reporting the underwater cable breaks that trade embargo, but it will still stand.
An analyst with Podcast 404 hopes the new connectivity will increase the effectiveness of government opposition.
“We know in the past the Internet has served as a great tool for nations and people to unite against the oppressive government ... Hopefully justice will be strengthened by this new cable link.”
Euronews reports several Cubans have already been keeping blogs. The network talked with Yoani Sanchez -- who criticizes daily life in Cuba on her blog Generation Y. She has a strong international audience, and her blog is now available in Cuba.
“The Cuban government unblocked access to Sanchez’s blog on Tuesday. She described the new cable as being the umbilical cord to freedom.”
A ZDNet blogger sees that as a positive sign - change could be coming to Cuba.
“...it does signal a possible regime or policy change to allow greater freedom of speech in the country. … It is becoming clear that steps are being taken to align the country to modernity from a third-world country to at very least a second.”
Next stop: Jamaica. Plans are in the works to run the cable from Cuba to Jamaica.

This is a high performance cleaver thats made for field termination of fiber optic cables. The easy two step system allows for terminating properly. Order online.
Optimized design for field connectorization. Suitable for loose tube and tight-buffered fiber optic cables. Metal cabinet construction. Jumper routing guides and jumper strain-relief point. Optional field-installable lock kit. Includes bracket for buffer tube fan-out kits.
The Silicon ZOOM II / Dual OWL 850 Test Kit is ideal for LAN managers and installers who need to do simple attenuation tests on their multimode networks.
The Silicon ZOOM II (Zeroed Output Optical Meter) is an economical fiber optic power meter designed to provide accurate testing of multimode fiber cables at 850nm wavelength. The 4-digit 7-segment LCD display shows power readings with a resolution of 0.01dB, power units in dBm, dB, or uW, and battery power level. The Silicon ZOOM II comes configured with a 2.5mm universal port for connection to SC, ST, and other connector types that have a 2.5mm ferrule. The Dual OWL 850 is an 850nm NIST traceable multimode light source. Its 850nm output is temperature-stabilized for accurate measurements. The Dual OWL 850 has two connector options: ST or SC.

This video is part of the Fiber Optic Communications course which starts from the basics of communication and then logically and quickly provides a comprehensive knowledge base in this essential communication technology. Training discussions include all aspects of fiber optic systems, including the business case, the technical fundamentals, deployment fiber optic systems and the latest advances.
As a result of taking this Fiber Optic Communications online training, you will be able to:
• Define basic terminology and concepts and take the lead in fiber optic discussions.
• Compare and contrast the features, functions, benefits and challenges of fiber optic communications with other wireline and wireless solutions.
• Match communication requirements with practical fiber optic systems.
• Specify optical fibers, cables, connectors, splices, and other transmission equipment.
• Participate in or manage all aspects of the fiber optic system life cycle from planning through design, installation, maintenance, upgrading and troubleshooting.
• Identify when and how to test fiber optic systems by use of power meters and OTDRs.
• Monitor fiber optics evolution to higher performance and greater market penetration.
