Gbps (Gb/s, Gbit/s) is the speed with which information is transmitted. It is normally used to measure the speed information in the ADSL/fiber addresses transmitted.

• 1 Gb/s is equivalent to 1,000,000,000 b/s.
• 1 Gb/s is equivalent to 1000000 kb/s.
• 1Gb/s equals 1000 Mb/s.

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.

The case MMF multimode fibers is when the core optical fiber is larger than the coating and it happens that a ray of light propagates through the fiber as multiple beams or modes. So the input and output have differences, this is also because many of the rays lose energy becoming heat. In multimode fibers the time dispersion and attenuation is greater than on other dand fiber. We show you a table for variations in multimode fiber.
