From both technical and economic perspectives, the ability to provide potentially unlimited transmission capacity is the most obvious advantage of DWDM technology. The current investment in fiber plant can not only be preserved, but optimized by a factor of at least 32. As demands change, more capacity can be added, either by simple equipment upgrades or by increasing the number of lambdas on the fiber, without expensive upgrades. Capacity can be obtained for the cost of the equipment, and existing fiber plant investment is retained.

Bandwidth aside, DWDM’s most compelling technical advantages can be summarized as follows:

• 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.

• 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.

• Dynamic provisioning—Fast, simple, and dynamic provisioning of network connections give

providers the ability to provide high-bandwidth services in days rather than months.

In the following sections we discuss some additional advantages, including migration from SONET and reliability

Optical fiber communication technology is now one of the important modern information transmission technologies. It has been applied in a general sense under the current information society background. When the global communication field and related industries are in a very downturn, optical fiber communication technology is still There has been some development. According to my country’s current development model in the field of communication technology, the application of optical fiber communication technology will replace all other information transmission methods, and become the mainstream technology in the future development of the communication field, leading mankind into the all-optical era.

HTF will join hands with you all to make our own contribution to the communications industry.
