| Correspond by letter the technique the trend that develop in recent years, especially the super-speed development of network of IP data give originally possessed of deliver the net the pressure, wave that brought bigness the emergence for dividing using technique than goodly resolved on originally possessed the fiber-optic net the smooth permit the ground problem. The information ages requests the capacity more and more big deliver network. Therefore, development the fiber optic deliver the potential of the information capacity, and increase current fiber optic of utilization, solve the antinomy of the fiber optic lack from the technique angle, and is a kind of method to get extensive approbation.The DWDM technique is a correspondence technique of a kind of fiber optic of forerunner comparison, and opposite mature. Its quick development makes us come in sight of an according to including of wave-length business the light deliver, the light exchange the whole light in inside the network will appear. Deliver the net capacity to increase at the same time, and deliver the net' s construction too gradually complicated. The safety condition that deliver the net affects the transmission safety of all business of its loading, and how to can satisfy the customer's need at the same time, and can still guarantee the stability that deliver. How to is better to resolve this problem. This design therefore enhance the network maintenance, and guarantee the network circulate is basis, primarily include the DWDM foundation the principle, system the test to request and wave for LUCENT DWDM equipments for involving brief introduction, primarily relating the actual gearing the process inside counting testing and trying circulating supporting, further tally upping having the actual meaning system maintenance method. Hope to perfect need, offering towards deliver the net' s safety management, satisfy loading on the light deliver net various business safety, dependable, efficiently of service. |
