Multi-mode Fiber: Fibers that support many propagation paths or transverse
modes are called multi-mode fibers, generally have a wider core diameter and
are used for short-distance communication links and for applications where
high power must be transmitted.
Single-mode Fiber: Fiber that support a single mode are called single-mode
fibers. Single-mode fibers are used for most communication links longer than
1,000 meters (3,300 ft).
SFP: Small form-factor pluggable , is a compact, hot-pluggable network
interface module used for both telecommunication and data communications
applications.
Optical Fiber Connector: Terminates the end of an optical fiber, and enables
quicker connection and disconnection than splicing. The connectors
mechanically couple and align the cores of fibers so light can pass. 4 most
common types of optical fiber connectors are SC, FC, LC,ST.
SC: (Subscriber Connector), also known as the square connector was also
created by the Japanese company Nippon Telegraph and Telephone. SC is a
push-pull coupling type of connector and has a 2.5mm diameter. Nowadays, it is
used mostly in single mode fiber optic patch cords, analog, GBIC, and CATV. SC
is one of the most popular options, as its simplicity in design comes along
with great durability and affordable prices.
LC(Lucent Connector) is a small factor connector (uses only a 1.25mm ferrule
diameter) that has a snap coupling mechanism. Because of its small dimensions,
it is the perfect fit for high-density connections, XFP, SFP, and SFP+
transceivers.
FC: (Ferrule Connector) is a screw type connector with a 2.5mm ferrule. FC is
a round shaped threaded fiber optic connector,mostly used on Datacom, telecom,
measurement equipment, single-mode laser.
ST: (Straight Tip) was invented by AT&T and uses a bayonet mount along with a
long spring-loaded ferrule to support the fiber.
USB: Universal Serial Bus is a standard that was developed in the mid-1990s
that defines cables, connectors and communication protocols. This technology
is designed to allow a connection, communication and power supply for
peripheral devices and computers.

the world created by the National Television Standards Committee in the 1950s.
NTSC utilizes an interlaced video signals.
PAL: Phase Alternate Line. A television standard in which the phase of the
colour carrier is alternated from line to line. It takes four full images (8
fields) for the colour-to-horizontalimages (8 fields) for the colour-to-
horizontal phase relationship to return to the reference point. This
alternation helps cancel out phase errors. For this reason, the hue control is
not needed on a PAL TV set. PAL, is widely used in needed on a PAL TV set.
PAL, is widely used in Western Europe, Australia, Africa, the Middle East, and
Micronesia. PAL uses 625-line, 50-field (25 fps) composite colour transmission

sound synthesizers, computers, and multimedia devices for musical performance
or show control. As with XML and JSON, the OSC protocol allows sharing data.
OSC is transported via UDP packets between devices connected on an Ethernet.
Brightness: Usually refers to the amount or intensity of video light produced
on a screen without regard to colour. Sometimes called black level.
Contrast Ratio: The ratio of the high light output level divided by the low light output level. In theory, the contrast ratio of the television system should be at least 100:1, if not 300:1. In reality, there are several limitations. Well-controlled viewing conditions should yield a practical contrast ratio of 30:1 to 50:1.
Colour Temperature: The colour quality, expressed in degrees Kelvin (K), of a
light source. The higher the colour temperature, the bluer the light. The
lower the temperature, the redder the light. Benchmark colour temperature for
the A/V industry include 5000°K, 6500°K, and 9000° K.
Saturation: Chroma, Chroma gain. The intensity of the colour, or the extent to
which a given colour in any image is free from white. The less white in a
colour, the truer the colour or the greater its saturation. Saturation is the
amount of pigment in a colour, and not the intensity.
Gamma: The light output of a CRT is not linear with respect to the voltage input. The difference between what you should have and what is actually output is known as gamma.

Frame: In interlaced video, a frame is one complete image.A video frame is
made up of two fields, or two sets of interlaced lines. In a film, a frame is
one still image of a series that makes up a motion image.
Genlock: Allows synchronisation of otherwise video devices. A signal generator
provides a signal pulses which connected devices can reference. Also see Black
Burst and Color Burst.
Blackburst: The video waveform without the video elements.It includes the
vertical sync, horizontal sync, and the Chroma burst information. Blackburst
is used to synchronize video equipment to align the video output.
Colour Burst: In colour TV systems, a burst of subcarrier frequency located on
the back part of the composite video signal. This serves as a colour
synchronizing signal to establish a frequency and phase reference for the
Chroma signal. Colour burst is 3.58 MHz for NTSC and 4.43 MHz for PAL.
Colour Bars: A standard test pattern of several basic colours (white, yellow,
cyan, green, magenta, red, blue, and black) as a reference for system
alignment and testing. In NTSC video, the most commonly used colour bars are
the SMPTE standard colour bars. In PAL video, the most commonly used colour
bars are eight full field bars. On computer monitors the most commonly used
colour bars are two rows of reversed colour bars.
Seamless Switching: A feature found on many video switchers. This feature
causes the switcher to wait until the vertical interval to switch. This avoids
a glitch (temporary scrambling) which often is seen when switching between
sources.
Scaling: A conversion of a video or computer graphic signal from a starting
resolution to a new resolution. Scaling from one resolution to another is
typically done to optimize the signal for input to an image processor,
transmission path or to improve its quality when presented on a particular
display.
PIP: Picture-In-Picture. A small image within a larger image created by
scaling down one of image to make it smaller. Other forms of PIP displays
include Picture-By-Picture (PBP) and Picture- With-Picture (PWP), which are
commonly used with 16:9 aspect display devices. PBP and PWP image formats
require a separate scaler for each video window .
HDR: is a high dynamic range (HDR) technique used in imaging and photography
to reproduce a greater dynamic range of luminosity than what is possible with
standard digital imaging or photographic techniques. The aim is to present a
similar range of luminance to that experienced through the human visual
system.

UHD: Standing for Ultra High Definition and comprising 4K and 8K television
standards with a
16:9 ratio, UHD follows the 2K HDTV standard. A UHD 4K display has a physical
resolution of 3840×2160 which is four times the area and twice both the width
and height of a HDTV/FullHD (1920 x1080) video signal.
EDID: Extended Display Identification Data. EDID is a data structure used to communicate video display information, including native resolution and vertical interval refresh rate requirements, to a source device. The source device will then output the provided EDID data, ensuring proper video image quality.
