4.11 ENGINEERING DWDM SYSTEMS

Engineering a DWDM system begins with a market investigation to understand the business opportunities and how the "to be built" system fits the communications market and the business portfolio. There are two golden rules to be met (that market research experts know well) for the success of new product: the "to be built" system must differ from any other product on the market, and it must offer a measurable benefit to the customer that no other previous product offers; that is, it has found a niche in the communications equipment space offering a solution to a known problem. When these rules are met, a tedious iterative process begins that involves the interplay of cost/benefit modeling, engineering, and market interaction. When this interplay is fine-tuned, the design process begins.

4.11.1 Parameters That Influence Optical Design

In this section, we do not address the market differentiator or the potential market opportunities present at different network layers, but we focus only on the engineering process that impacts the design of a DWDM system and the quality of signal and service. First, however, we examine the key parameters that influence the design of a DWDM system and a network. These...

Products & Services
Fiber Optic Connectors
Fiber optic connectors are used to align and join two or more fibers together to provide a means for attaching to, or decoupling from, a transmitter, receiver, or other fiber optic device.
Fiber Optic Receivers
Fiber optic receivers are instruments that convert light into electrical signals. They contain a photodiode semiconductor, signal conditioning circuitry, and an amplifier.
Lasers
Lasers are devices that produce intense beams of monochromatic, coherent radiation. The word "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation.
Diode Lasers
Diode lasers use light-emitting diodes to produce stimulated emissions in the form of coherent light output. They are also known as laser diodes.
