Carriers of a Fiber Optic

 Wholesale customers worldwide rely on fiber optic solutions for international transport in order to meet the growing communication needs. With the advent of 10 Gigabit Ethernet network also known as 10GbE, physical limitations and also the properties of the fiber optic carrier facing new challenges. The network designer must take into account all these aspects before designing a perfect network. As the speed increases in these networks, the effects of the fiber as the intermodal polarization and chromatic dispersions have become an important factor. This is in addition to the considerations of the network designer that he or she needs to understand and overcome in order to build a network adecuada.Hay different types of classifications carrying optical fibers, such as OC-1, OC-3, OC-12, etc. The OC-1 is the optical carrier that is used for a SONET line and has a speed of about 51.84Mbits / sec. The OC-3 is the optical carrier that is used in the normal line of the network and having a bit rate of 1552.52 m / sec. The optical carrier can also be compared with the SDH in which case the OC-3 may be represented as level electrical STS-3.
