Enterprise networks face a condition called fiber exhaust when the demand for backbone fiber exceeds the availability of installed fiber strands. The most obvious and expensive solution to fiber exhaust is to install more fiber. However, it’s a costly proposition. It is estimated at about $70,000 per mile, most of which is the cost of permits and construction rather than the fiber itself. There is another solution to solve fiber exhaust is to increase the bit rate of existing systems. Using TDM, data is now routinely transmitted at 2.5 Gbps and, increasingly, at 10 Gbps. Recent advances have resulted in speeds of 40 Gbps and 100 Gbps. The electronic circuitry that makes this possible, however, is complex and costly, both to purchase and to maintain. DWDM Gives the Most Cost-effective Solution for Fiber Exhaust Since two solutions mentioned above are not cost-effective enough, how to solve this problem? In fact, there is a third solution that is to...
