Why Cable Pros Select Fiber Optic Over Copper Cabling

cable,cabling,installation ,Washington DCDuring your consideration of the kind of cable that should be selected for your IT network, several factors come into play. One of the decisions you will need to make is whether to use copper or fiber optic cabling.


Copper certainly has plusses. It is already installed in numerous sites and is less costly for connecting network components. Although fiber optic cabling has a higher price tag, it has key advantages that make it more attractive than copper for creating structured cabling infrastructure.


The following are five reasons why most cable professionals select fiber optic over copper cabling.



Durability


Fiber optic cables have longer service lives than copper, decreasing maintenance costs and downtimes from replacements. Although fiber optic wires are made of glass, copper wires are more susceptible to being damaged.



Fiber Optic is Faster


When evaluating the transmission of copper wire to that of fiber optic, the contest can be simplified to the comparison of the speed of electrons to the speed of photons. Although C transmissions do not move at the speed of light, they are still extremely fast by moving just 31% slower than the speed of light!



Low Attenuation


Over long distances, fiber optic cables will undergo much less signal loss than copper. This quality is termed “low attenuation.” Due to attenuation, copper cables are capable of transmitting information up to a maximum of 9,328 ft, when it then loses power. In contrast, fiber optic cables are capable of transmissions up to 24.8 miles.



Resistance to EMI (Electromagnetic Interference)


If improperly installed, copper cables will generate electromagnetic currents that result in EMI inside nearby wires, which can cause serious problems throughout a network. On the other hand, fiber optic cables are not conductors of electricity.



Safer


Fiber optic cabling is safer because it won’t be a fire hazard. The reason is no electrical current travels through fiber optic cables.

Ethernet Crossover Cable Basics

24 Jan 2018

Cable Installation, Cabling, Washington D.C.The crossover cable connects two Ethernet network devices to each other. They were invented for temporarily supporting host-to-host networking when a network router or another intermediary device is not available. Although crossover cables appear the same as a standard straight-through (patch) Ethernet cable, their internal wiring structures are different.



Straight Through vs. Crossover


A straight-through cable is used for connecting two different kinds of devices, such as a network switch to a computer. In contrast, a crossover cable is for connecting two devices that are identical.


The straight-through cable’s ends can be wired in any manner, but both ends must be identical. This is different from the crossover cable’s internal wiring, which reverses the signals for receiving and transmitting. The first and third wires and the second and sixth wires are crossed.


High-quality Ethernet crossover cables have special markings which allow users to distinguish them from straight-through cables. They are often red in color and the word "crossover" will appear on its casing and packaging.



Crossover Cable Needs


Crossover cables came into use during the 1990s and 2000s because the most common types of Ethernet were unable to support direct cable connections between hosts. Intended for using specific wires for both receiving and transmitting signals, the original and Fast Ethernet standards required the communication of two endpoints through an intermediary device to avoid conflicts.


The Ethernet feature MDI-X has auto-detection for the prevention of signal conflicts, enabling the Ethernet interface to automatically determine and negotiate the expected signaling convention of the device at the other end of the cable. The majority of home broadband routers and Gigabit Ethernet adopted MDI-X.


As a result, crossover cables are only necessary for the connection of two Ethernet client devices if they are not configured for Gigabit Ethernet. Nowadays, Ethernet devices are compatible with crossover cables because they can automatically detect them.



Ethernet Crossover Cables Usage


Crossover cable usage should be limited to direct network connections. When a user tries connecting a computer to an antiquated router or network switch via a crossover cable rather than a standard cable, the link can be prevented from working.
