Enterprise Links

2. Enterprises links face an increasing need for a number of high bandwidth connection between their site.
Many Enterprises maintain two data centers that separated by few km. All transactions are mirrored at both sites. This allows the enterprise to recover quickly from disaster where one of the centers fails
Lower real estate costs at the cheaper site. The large mainframes at these data enters need to be interconnected by several hundred channels each at up to a few hundred Mb/s.
IBM Mainframes communicate using 100s of ESCON channels

3. WDM in Enterprises Network
WDM is attractive for Enterprise Links because the data center tend to be located in dense metropolitan areas where most of the installed fiber is already in use & these network use a large variety of protocols and bits rate
WDM system are being installed in large Enterprises networks in United States & all over Europe
Links are short so no need to use optical amplifier or generator
