Thinking about rolling up your sleeves and designing a CWDM or DWDM network? You probably understand the basics of wavelength division multiplexing and its great potential to provide capacity expansion and flexibility at a cost you can afford. Now you need to know where to start.

The first step in the network design process is assessing both your current requirements and the need for additional bandwidth as your network grows. Next, there are some important factors to consider before you can design and build the network. Here’s a step-by-step guide, with practical considerations and recommendations, to help you get the best fiber optic network for your specific needs.

Amplification boosts the signal in the transceiver so that it can overcome the attenuation, i.e. it increases the distance over which the data between two sites can be transmitted.

Calculating the optical link budget in an embedded WDM network
When designing a complete embedded WDM solution, the most important task is calculating what is commonly referred to as the optical link budget. It starts off with the transceiver power budget but also considers all the potential losses from the transmitter side, through the multiplexers, patch panels and dark fiber to the receiver side of the system. Simply put, the link budget determines whether the selected transceiver will be powerful enough to transmit the signal across the fiber despite the losses on the way

Embedded xWDM solutions – As easy as 1-2-3

The simplest way to create a wavelength division multiplexing (WDM) network is using an embedded xWDM solution. In an embedded solution, a CWDM or DWDM transceiver is connected directly into a SAN or IP switch. Each signal that comes from the different transceivers is then connected to a multiplexer, which gathers them together and transports them over a single optical fiber link.

Optimizing the use of fiber with multiplexer

A WDM multiplexer, sometimes referred to as a mux, is the key to optimizing, or maximizing, the use of the fiber. The multiplexer lies at the heart of the operation, gathering all the data streams together to be transported simultaneously over a single fiber. It does this by taking multiple input signals and combining – multiplexing – them together on to a single, common line output. The multiplexed signal can now be transmitted on a single fiber or fiber pair over the optical network. At the other end of the fiber, the streams are demultiplexed, i.e. separated into different channels again.

Of all the methods available for corporate data centers and campuses to connect traffic and replicate data between sites, the majority depend on the availability of a dark fiber network. If a fiber is available (either owned or leased) it’s possible to run a private network to connect sites together.
