WAN, which is also known as wide area network is a network that consists of several private computers or organizations. Today with the speed that is in LANs is no longer necessary to use WAN

As network cables, fiber optic cables have their international standards. In this instance they are divided into OM1, OM2, OM3 and OM4. The difference between them is based on differences in bandwidth, speed, inside diameter as seen in the table below. To help clarify some concepts, would 9/125 (inside diameter/outside diameter). In the bandwidth can be 850nm, 1350nm or one550nm (nanometers). In the case of application we have put a guidance to help understand the concept, but actually it can be used in many areas.

ABS material (acrylonitrile butadiene styrene) is a type of thermoplastic that is very resistant to impact or shock.

Its applications are several, for example is a material widely used in the manufacture of interiors or components of cars such as moldings, as well as in products for domestic use such as toys, tools, housings of electrical devices etc.

One of its most important characteristics is its great tenacidad in almost all types of temperatures.

Being a very hard material has good chemical resistance, low water absorption and high resistance to abrasion, where other types of plastics would be more brittle.

This type of material is becoming very famous in the particular field and widely used due to the great growth in the sales of domestic 3D printers, the main printing raw material.next to the PLA.

Identification of ABS
Parts that are made of ABS material must be marked in accordance with ISO 11469 (DIN 58840).
