INTRODUCTION TO BANDWIDTH

Communication over large distances happened through landline telephones. In a landline telephone, analogue signals, are converted to data bytes, transferred through terrestrial telephone cables, and then, reconverted to analogue signals. Today, people use the ubiquitous cell phone to fulfill the same purpose. In this case, the sound bytes are transferred to the other end by optical fiber cables laid below the ground level. These are then, connected to cell phone towers, acting as receivers and reflectors of signals. Each optical fiber cable can transfer traffic based on its bandwidth. Our internet also works on the same principle. However, in this case, there is transfer of data, which includes pictures, statistics, video clippings, etc. The, larger the bandwidth of the optical fiber cable, more is the speed of transfer of data. It is analogous to the transfer of water through a pipe. Fiber optics is a technology that uses glass (or plastic) threads (fibers) to transmit data packets. A fiber optic cable contains a bundle of glass threads, each of which is capable of transferring messages modulated onto light waves.

OC-3 DEMYSTIFIED

OC-3 is an abbreviated term for Optical Carrier Level 3, and is used to specify the speed of data transfer through optical fiber cables over SONET (Synchronous Optical Network). More explicitly, SONET includes a set of signal rate multiples for transmitting digital signals on optical fiber. Here OC stands for Optical Carrier and the number following it signifies the speed at which data transfer occurs, conforming to SONET standard. The base rate of OC-1 is 51.84 Mbps, so that of OC-3 would be 155Mbps. This only means that this cable is capable of taking, synchronizing, and transferring data and voice at the speed of 155 Mbps, without any hindrances. Thus, an OC-3 is equivalent to 84 T1’s or 3 DS3’s/T3’s. In other words, an OC-3 circuit is capable of 2,000 simultaneous voice transmissions, along with variable data types alongside the voice packets.

WHY OC-3

It can meet the strict requirements, with regard to latency and line quality. It gives a complete end-to-end monitoring of bit errors, and it is a dedicated cable for our usage. With an OC-3 bandwidth solution, one’s network can deliver optimum speed and load for any large-scale voice/data application requirements that one may have, with reliable and secure digital technology performance. One important benefit of OC-3 bandwidth, is that it is burstable, thus allowing for future increase in bandwidth needs. A burstable OC-3 is an ideal solution for a business, seeking ultra fast connectivity and possibility for future increase in bandwidth requirements. Additionally, an OC-3 bandwidth provides with low cost and flexible pricing plans. Another benefit of OC-3 bandwidth is that if the primary connection is unable to pass data packets, then the internet dedicated OC-3 shadow connector automatically takes over the IP traffic. Border Gateway Protocol (BGP) handles this change in traffic flow, thus, obviating the need for a manual configuration change.
