Why wouldn’t I skip category 6 and go straight to optical fiber?

A:
You can certainly do that but will find that a fiber system is still very expensive. Ultimately, economics drive customer decisions, and today optical fiber together with optical transceivers is about twice as expensive as an equivalent system built ... more

Does Center for Sight have an optical shop?

A:
Center for Sight does not have an optical shop. During your visit, the doctor will determine the refractive state of your eyes and recommend an optical source suited to your needs and desires. ... more

How will out-of-control Process Restraint affect CD/DVD Optical burners?

A:
CD/DVD Burners typically don't use enough of the processor to be restrained, as they are usually waiting on disk or optical drive I/O. It is actually more likely that a buffer underrun would be prevented by Process Lasso because if you were in such a ... more

What is an Optical Time Domain Reflectometer, and Why is it Important in the Fiber Optic Industry?

A:
An optical time domain reflectometer or OTDR for short is a high tech tool used in the fiberoptic industry. An optical time domain reflectometer measures the time and intensity of light which is reflected through a fiberoptic cable. OTDRs can find fa ... more

Why interference doesnot occur in optical fibres?

A:
Fiber has a core and a cladding; light reflect on the transition surface between the core and the cladding Light is transmitted by total reflection inside the fiber, that means that no light is refracted, so the light keep inside the fiber. External ... more

How Are Optical Fibres Used In Tele-communication?

A:
Optical fibres are actually plastic or glass fibres that are designed in such a way that they confine light (as much as possible) in a form that is propagating. Optical fibres are widely used in telecommunications. Optical fibres are used in this rol ... more

Is the detection of optical activity in extraterrestrial samples a safe indicator for life?

A:
Since Pasteur's times it has been accepted that optical activity and life are intimately correlated with each other, i.e. the one could not exist without the other. This argument logically allows the following speculation related to interplanetary ex ... more

What is an optical buying group?

A:
The old adage of strength in numbers is true. An optical buying group brings together eyecare professionals to combine their purchasing power. Collectively, our members do a large volume of business, which allows HMI Buying Group to negotiate with ma ... more

What is the difference between optical archiving and data archiving?

A:
Optical archiving is an integration component for document and archive data storage. Optical archiving uses the ArchiveLink interface, which can be used for both the storage of documents and the storage of archive files. ... more

How does the Phantom Contour Projector compare with the Wendel Optical Projector?

A:
The two projectors are very similar in design except for the light source, housings and mounting techniques. Utilizing a 75-Watt MR16 lamp our custom lenses collect, condense and focus the light to levels exceeding the 150-Watt lamp used in the Wende ... more
