1. What was the planned strategy of Level 3 Communications in the late 1990s? Ans. To offer low-priced fiber-optic network that covers connections to major cities in the US focusing on the internet traffic for service providers and corporations. The plan starting from gathering funding from investors to build up a high capacity fiber-optic network that linked major cities in the US‚ then cut prices to attract major users of the networks including corporations‚ Internet service providers like AOL

R & D to deliver with innovative technology that continually put Corning in the driver seat as the lead supplier in new glass products. In the late 1990’s and early 2000’s Corning started to have some serious success with telecommunications fiber optics. With a new CEO‚ who was obsessed with growth‚ the company decided to spin off some of their other ventures to focus on what they believed to be the areas that held the most potential for growth. This led to the sale of the medical services‚ which

A PON reduces the amount of fiber and central office equipment required compared with point-to-point architectures. A passive optical network is a form of fiber-optic access network. In most cases‚ downstream signals are broadcast to all premises sharing multiple fibers. Encryption can prevent eavesdropping. Upstream signals are combined using a multiple access protocol‚ usually time division multiple ac

broadband does appear to be trending in a particular direction. Right now one of the biggest future trends in broadband is a service which is being offered by Verizon. This new service is called Fios. Fios is touted to be the latest in fiber optic technology. It delivers laser generated pulses of light‚ riding on hair thin strands of glass fiber‚ all the way to your front door(Verizon.com). Verizon has already begun to install this system in parts of California‚ Florida‚ and Texas. Along

Case Analysis: Optical Fiber Corporation Introduction Optical Fiber Corporation (OFC) is a financially successful‚ albeit relatively small manufacturer of multimode optical fibers. The company was founded in 1990. The founders were able to enter the market largely on the basis of acquiring patent licenses from larger optical fiber firms. These licenses restricted competition between the entities and provided OFC with instant access to optical fiber technology. In return‚ OFC’s customer

Dense wavelength division multiplexing (DWDM) is a technology that puts data from different sources together on an optical fiber‚ with each signal carried at the same time on its own separate light wavelength. Using DWDM‚ up to 80 (and theoretically more) separate wavelengths or channels of data can be multiplexed into a light stream transmitted on a single optical fiber. Each channel carries a time division multiplexed (TDM) signal. In a system with each channel carrying 2.5 Gbps (billion bits per
