What is gain in amplifier?

What is gain in amplifier?

Gain. Gain is the ratio of output voltage to input voltage of an amplifier, where VIN1 and VIN2 are two inputs, subtracted. In a real circuit, the gain will be frequency dependent, but let us start with consideration of the gain in an ideal amplifier.

Does fiber cable need to be grounded?

A fiber-optic cable including non-current-carrying metallic components, such as armor or metallic strength members, is deemed conductive, according to NEC Article 770. This is why, according to NEC Article 770.100, conductive fiber-optic cables must be joined and grounded.

How did splicers become splicers?

Remnants of Rapture's human population, Splicers are the result of ADAM use, which skyrocketed during the violence of the Rapture Civil War. During the conflict, and the chaotic days that followed, most of the city's citizens fell victim to the Splicers or abused ADAM to the point of becoming Splicers themselves.

What is the longest cable in the world?

SEA-ME-WE3 or South-East Asia - Middle East - Western Europe 3 is an optical submarine telecommunications cable linking those regions and is the longest in the world.

What dBi means?

The symbol is an abbreviation for "decibels relative to isotropic." The dBi specification is based on the decibel , a logarithm ic measure of relative power .

What is a power ratio?

Power ratio shows how much revenue a broadcast media company earns compared to how much it would be expected to earn given its market share. It is calculated as follows: Company Revenue / (Audience Share * Total Market Revenue)

Is the optical detector used in OTDR?

An OTDR combines a laser source and a detector to provide an inside view of the fiber link. The laser source sends a signal into the fiber where the detector receives the light reflected from the different elements of the link.

What is coherent OTDR?

The Coherent OTDR (C-OTDR) MW90010A is a measuring instrument for detecting faults in ultra-long optical submarine cables of up to 12,000 km including multiple repeaters (EDFAs). It is the ideal solution for evaluating new cables at service deployment as well as for troubleshooting in-service faults.

How do I become a splicer technician?

Cable Splicer: IndustryApplicants are eligible once they have completed two years of work experience in the medium voltage shielded power cable industry. According to the experts at NCSCB, medium voltage cable splicing certification includes a written and performance exam in which splicing competency is assessed.

Why do we splice?

Splicing is generally used to terminate singlemode fibers by splicing preterminated pigtails onto each fiber. It can be also used to mix numbers of different types of fiber cables like connecting a 48 fiber cables to six 8 fiber cables going to different places.
