ABSTRACT:

The present technology in computing and communications lead to develop most secured netwroks in internet technology.To compremise these secuirty measures thousands of malicious codes are been developed and its counter measures are been created.Network plays a most important role which can be explained with the following diagram.

(Source: Case Study)

In this type of fiber the network which has been created should be redesigned and a new network is formed.here in this we will be creating a new network with the given ip address and the following subnets will be created by using the VLSM.Now we will create the communication in the network and also fasten the communication by using the latest technology.this will be further used in the companies for their future requirements.for the future requirements we will create the new network by using this fiber.

A large core photonic crystal fiber for transmitting radiation having a core comprising a substantially transparent core material and having a core diameter of at least 5.the fiber also comprises a cladding region surrounding the length of core material,where in the cladding region comprises a first substantially transperent cladding material having a first refractive index and where in the first substancially transperent cladding material has embedded along its length a substancially periodic array of holes where in the holes are filled with a second refractive index less than first refractive index,such that radiation input to the optical fibre is transmitted along the length of the core material in a single mode of propagation.in a preffered embodiment,the core diameter may be atleast 20 and may as large as 50.the fiber is capable of transmitting higher power radiationthen convention fibre whist maintaining propogation in single mode.

OPTICAL FIBER:

(source:google images)

Single mode fibre optic cable has a small diameter core (9/125 microns) that allows only one mode of light to travel (propagate).The number of light reflections created as the light passes through the core decreases, lowering attenuation and creating the ability for the signal to travel faster, further. This Communication is mainly used in long distance; higher bandwidth runs by Telco’s, CATV companies, and Colleges and Universities. Single mode fibre is usually 9/125 in construction.  This means that the core to cladding diameter ratio is 9 microns to 125 microns.
