Full vs Half Duplex …
In the world of digital communication, full-duplex means that a system or circuit is capable of both transmitting and receiving data at the same time. In contrast, half-duplex means that communication can only go in one direction at a time.
A good analogy is comparing telephones to walkie-talkies; phones are full-duplex, and walkie-talkies are half-duplex.
RoHS is an environmental protection regulation that has been enacted by the countries of the European Union and widely referred by to by other countries. The regulation prohibits the use of certain toxic chemicals in the manufacture of electrical and electronic devices. Tiny amounts of lead, mercury, cadmium, and other chemicals have been used in the past to build circuit boards and other electronic components.
Now, manufacturers are switching to greener, less dangerous materials and processes in order to comply with the new regulation. CABLExpress is vigilant to make sure that our products adhere to the RoHS standards.
In what is both an informative and interesting special edition of Cable Talk. Josh Taylor Sr. Product Manager uses the Skinny-Trunk™ harnesses and Z-Mount brackets to cable up (3) 48 port 10G blades on the Cisco 7000.
This unique solution allows you to manage the density of cables in an attractive, highly manageable and time saving way. Check it out I think you will be impressed.
The LC connector is a Small Form Factor (SFF) connector for fiber optic cables.
Developed by Lucent (LC stands for Lucent Connector), it has gained wide acceptance by manufacturers of 10 / 100 Gigabit optical transceivers. LC connectors have a squarish shape, and are usually held together in a duplex configuration by a plastic clip.
An S-video signal is made up of two parts—luminance and chrominance.
The luminance signal (usually abbreviated as “Y”) carries greyscale brightness information, which is basically black-and-white video.
The chrominance signal (abbreviated as “C”), carries color detail information.
Because the two lines are separate, more bandwidth is available and S-video provides a better picture than composite video, where all information is carried on one conductor.
What’s the maximum distance that a VGA signal can travel?
There’s not a firm, exact answer to that question. Much depends on other factors, such as the quality of the source & display, the installation environment, the preferences of the audience, and the quality of the cable.
For long runs (50 feet and longer), a booster is recommended to compensate for the distance.
Did you know how small the glass core is in a fiber optic cable? Singlemode fiber cables have a glass core diameter of 9 microns, or 9 millionths of a meter.
By comparison, the copper conductors used in most network cables (24 AWG wire) is over 500 microns thick, and the thinnest human hair (blonde, by the way) is about 20 microns thick.
The material used to make up a coaxial cable’s dielectric does have an effect on performance. The insulating material of a dielectric affects the velocity of propagation, or how fast the signal travels down the wire. Also, a dielectric should be stiff enough to hold its shape when bent or flexed.
Any deformity in the shape of a coaxial cable’s dielectric affects impedance, which can create return loss.
Quality cable assures you will have the signal level you need when you need it. All cables do not have the same performance qualities.
