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.

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.

SFP transceiver, English small form-factor pluggable transceiver (in Spanish transceiver small form factor pluggable) or, in English, SFP transceiver and abbreviated known as SFP, it is a compact, hot-pluggable transceiver used for data communications applications and telecommunications. They are designed to support SONET, Fibre Channel, Gigabit Ethernet and other common standardsications.

A Gigabit Interface Converter (GBIC, for short) is a module that is available in many forms, depending on the model and manufacturer of the brand. Each has the same function which is to increase the speed of data transfer through a network. Companies that need to transfer large amounts of data quickly, sometimes using a GBIC module for greater control and profitability. A GBIC moduleIt allows users to reconfigure fiber links, set costs of adapting the receptor and link distances network topologies and requirements established. Used in an optical fiber or Ethernet system, the GBIC modules can update, change or connect without turning off the computer. This flexibility eliminates the need to replace the entire network system together.

One hertz is one cycle per second, meaning repeating cycle as an event. For example, hertz is applied physics measuring the number of times for a second wave (either acoustic or electromagnetic) is repeated or can be applied, among other uses, to ocean waves that reach the Beach vibrations per second or a solid. The quantity that measures the frequency hertz is called,in this regard, the inverse of the period. One hertz is an oscillation frequency of suffering a particle over a period of one second.
