How DWDM System Components Work Together with DWDM Technology?
As DWDM system is composed of these five components, how do they work together?
1. The transponder accepts input in the form of a standard single-mode or multimode laser pulse. The input can come from different physical media and different protocols and traffic types.
2. The wavelength of the transponder input signal is mapped to a DWDM wavelength.
3. DWDM wavelengths from the transponder are multiplexed with signals from the direct interface to form a composite optical signal which is launched into the fiber.
4. A post-amplifier (booster amplifier) boosts the strength of the optical signal as it leaves the multiplexer.
5. An OADM is used at a remote location to drop and add bitstreams of a specific wavelength.
6. Additional optical amplifiers can be used along the fiber span (in-line amplifier) as needed.
7. A pre-amplifier boosts the signal before it enters the d e muliplexer.
8. The incoming signal is demultiplexed into individual DWDM wavelengths.
9. The individual DWDM lambdas are either mapped to the required output type through the transponder or they are passed directly to client-side equipment.
Applications
DWDM has capability to expand capacity and can serve as backup bandwidth without a need to install new fibers, thus it is ready made for long distance telecommunication services.
DWDM can also be used in various networks like sensor networks, remote radar networks, tele spectroscopic process control network and many more networks.
By the use of only two fibers, 100% protected ring with 16 separate communication signals can be constructed deploying DWDM terminals as these are self healing rings.
In order to meet the demand in fast growing industrial base, DWDM system can be used for existing thin fiber plants as these plants cannot support high bit rates.
Benefits
1. Transparency—Because DWDM is a physical layer architecture, it can transparently support both TDM and data formats such as ATM, Gigabit Ethernet, ESCON, and Fibre Channel with open interfaces over a common physical layer.
2. Scalability—DWDM can leverage the abundance of dark fiber in many metropolitan area and enterprise networks to quickly meet demand for capacity on point-to-point links and on spans of existing SONET/SDH rings.
3. Dynamic provisioning—Fast, simple, and dynamic provisioning of network connections give providers the ability to provide high-bandwidth services in days rather than months.
