SX LX CX what do these mean?

: Fast Ethernet running on two pairs of Category 5 twisted pair wires;

Fast Ethernet running on fiber, which can be singlemode or multimode;

Short-distance links for multimode fibers up to 550 meters.

For the link of single-mode or multimode fiber, the maximum distance of single-mode fiber is 10 km, and the distance of multimode fiber is 550 m.

1000m Ethernet running on coaxial cable.

SX stands for 1000Base-SX, which means a single-fiber 1000Mbps baseband transmission system, which can only use multimode fiber.

LX is a physical layer specification defined in 1000BASE-LX, for fiber cabling Gigabit Ethernet. The lx in 1000BASE-LX stands for long wavelength, and the main fibers used are: multimode fiber, 50 m multimode fiber, and 9 m single-mode fiber.

CX is 1000Base-CX and is suitable for connections between switches, especially for short-distance connections between backbone switches and primary servers.

The 1000BASE-CX corresponds to the standard and uses 150 Balanced Shielded Twisted Pair (STP).

SX and LX refer to the model of optical module, SX is a short-distance optical module, which is generally suitable for multi-mode optical fiber, and the transmission distance is < 10 km; LX is generally suitable for single-mode fiber, with a transmission distance of < 25 km; LH generally refers to ultra-long-distance optical modules, the transmission distance is 25-70 kilometers, if the distance is less than 25 kilometers, then an attenuator should be added between the LH to prevent damage to the LH module.

What is TX, FX, SX, LX, CX?

100BASE-TX: Fast Ethernet running on two pairs of Category 5 twisted pair wires;

100BASE-FX: Fast Ethernet running over fiber, which can be singlemode or multimode;

1000BASE-CX: 1000M Ethernet running over coaxial cable.

: Fast Ethernet running on two pairs of Category 5 twisted pair wires;

Fast Ethernet running on fiber, which can be singlemode or multimode;

Short-distance links for multimode fibers up to 550 meters: Links for single-mode or multimode fibers up to 10 km for single-mode fibers and 550 meters for multimode fibers.

1000m Ethernet running on coaxial cable.

SX is short for mathematics.

mathematics [English: mathematics, from the ancient Greek máthēma); Often abbreviated as math or maths], it is a discipline that studies concepts such as quantity, structure, change, space, and information.

Mathematics is a general means for humans to strictly describe the abstract structure and pattern of things, and can be applied to any problem in the real world, and all mathematical objects are inherently artificially defined. In this sense, mathematics belongs to the formal sciences.

And not natural science. Different mathematicians and philosophers have a range of opinions on the exact scope and definition of mathematics.

in the history of mankind.

Mathematics plays an irreplaceable role in development and social life, and it is also an indispensable basic tool for learning and researching modern science and technology.

Structures: Many mathematical objects such as numbers, functions, geometry, etc., reflect the internal structure that defines the continuous operations or relationships within them. Mathematics is the study of the properties of these structures, such as:

Number theory is the study of how integers are represented in arithmetic operations. In addition, it is not uncommon for different knots to reconstruct but have similar properties, which makes it possible to describe their state by further abstraction and then by axioms on a class of structures, and the study is to find the structures that satisfy these axioms among all the structures.

Thus, we can learn about groups, rings, domains, and other abstract systems. Taking these studies (through structures defined by algebraic operations) can form abstract algebra.

of the field. Due to its great versatility, abstract algebra can often be applied to seemingly unrelated problems, such as the drawing of ancient rulers.

The problem was finally solved using the Galois theory, which involved domain theory and group theory.

Another example of a front-miss in algebraic theory is linear algebra.

It is a vector space that has quantity and directionality to its elements.

A general study was made. These phenomena show that geometry and algebra, which were previously thought to be unrelated, actually have a strong correlation.

Combinatorics is the study of methods for enumerating number objects that satisfy a given structure.

SX means an acronym or pinyin abbreviation for some simple languages.

Generally speaking, SX has not yet been found to have a specific meaning in the field of professional training and rock industry, but it is not excluded that it has a specific meaning in the language of the Internet. For example, it can be an abbreviation of SCENIX, SHOPSTIX, STATICX, or a symphony representing X in the field. In the field of physics, sx can refer to subluxation, and the above is inferred through English abbreviations.

In addition, sx can also be regarded as an abbreviation of Chinese Pinyin, which is also a way of communication derived from the network environment. For example, Shaanxi, the rest, and the realization can all be the meaning of sx. If you want to accurately understand the meaning of SX, you need to experience and analyze it in a specific context.

SX has multiple meanings

Starting from the meaning of SX, it can be found that this abbreviation often occurs in the process of people communicating now, which is also a network language that is used more frequently. With the continuous acceleration of the development of the Internet, most of the communication between people is on the network information platform, so they can only contact each other by typing.

For the sake of convenience, it is easy to derive an abbreviation like sx to express or represent a specific meaning. In addition, a similar phenomenon can occur in many specific cultural circles, especially in entertainment cultural circles, where pinyin letters are often used instead in order to extract and emphasize a certain meaning.
