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.

Closed circuit television, or CCTV (stands for closed circuit television) surveillance is a technology designed to monitor a variety of environments and activities. It is called closed, that, contrary to what happens with the media, all components are linked. In addition, unlike conventional television, this is a security system designed to

LSHF Cable (Low Smoke Halogen Free Cable) or also called LSZH (Low Smoke Zero Halogen) is a type of international classification that is used to cover the wires in the cable industry both steel and other types. LSHZ has a thermoplastic coating that propagate little heat sources. Another carasterística do not emit toxic gases or fumes when exposed to flame. You have to take into account that surfacertas facilities may be required by the competent authority using these cables.
