Enjoy Great Bandwidth with Optical Fiber Cable

Fiber Optics hold the future of communication because of tremendous capacity to handle high speed data transfer with very little noise factor. In addition, the power loss in the optical fiber cable is very low making it an ideal device for carrying signals over a very long distance without significant distortion or requirement of amplifiers of repeaters. Optical fiber cables consist of one or more optical fibers bundled together with a thick protective covering giving fibers the form of cable.

Fiber Optics consists of essentially two layers of core and cladding to make communication through an optical fiber possible. The inner layer is called as core while the outer one is called as cladding. The basic idea is to have two different media with different refractive index to allow the light to refract as it moves along the fiber optic cable. As the signal, which is in the form of light, travels from denser to rarer medium bend away from the normal and are ultimately reflected back due to a phenomenon known as total internal reflection that is the base for optical fiber communication. Optical fibers are made of glass and are very thin of the order of nano-meters in diameter. Thus they are very delicate and needs a thick protective layer.

Role of passive devices and passive networks in any communication including optical fiber communication cannot be taken for granted. Passive Optical networks commonly abbreviated as PON refers to a meaningful interconnection of optical fiber cable and other passive networks that cannot generate any power on their own. There are many key elements of a PON including splitters and gepon onu. Splitters as the name suggest splits the beam of light into several beams travelling through an optical fiber. It is one of the main parts of passive optical networks. There are various types of splitters available including Fused Biconical Taper (FBT) splitter and Planar Lightwave Circuit (PLC) splitters.

PLC splitter is the latest additions to the world of splitters. It offers much better control on splitting the lighy with precise control over intensity and distribution of light. EPON and GEPON are two types of passive optical networks related to optical communication. Gepon onu is another in the series of passive devices of optical networks. You can connect a huge number of devices using the same and that too without any undue leakage of power. All these devices are very compact making them perfect for optical fiber communication.

Fiber Media converter and Other Essential Components of Optical Fiber Communication

Fiber Optic Communication is the most advanced technique for wired communication and offers many advantages like extremely low loss, low power requirement, high bandwidth and many more. However, traditional cables and systems that make use of copper wires cannot be replaced with optical fibers as it is a gradual process and it takes time to replace the old systems completely.

For the time being we are into the stage of transformation and often there is need to interconnect the fiber optic cable to a traditional cable like twisted wire or co-axial cable. It is not possible to connect the two different media directly as their operating characteristics are totally different. This is where Fiber Media Converter comes so handy and allows easy interconnection of optical fiber cable to any other cable. A fiber optic media is basically a networking device allows the engineers to establish connection between the copper based structured cabling system and fiber optic cabling based systems. There are many more devices and components that are required for optical fiber based networking systems like fiber optic patch cord, SPF etc.

Overview on Optical Fiber Patch Cord

Unlike normal twisted wire, it is not possible to connect fiber optic cables to the devices unless you have proper connecters, plugs and caps at the ends. A fiber optical-based patch cord is like any other patch cord. Patch cord refers to a piece of wire with suitable connectors at each end that allows transfer of signals or power from one system to another or simply interconnects two systems. fiber optic patch cord is small section of optical fiber cable with connectors at each end to enable the cord to connect to variety of optical fiber networking devices like optical switch, CATV cable and other telecommunication equipments.

SPF in fiber optic communication stands for small form- factor pluggable which is a trans-receiver device that is capable of both transmitting and receiving the signals. SPF is particularly a fiber optic plug that acts as an interface between a network device’s motherboard and a fiber optic cable or traditional copper cable. SPF is a perfect component especially designed for the optical fiber communication. It has an extremely small size, which enables it to be used with optical fiber cables and support high-speed data rate. They are commonly found at the back of the networking devices like routers, Ethernet switches, firewalls, network interface cards, motherboards etc.
