Raman Amplification in Storage Area Networking
by Per B. Hansen - Director, Business Development, Optical Solutions ADVA Optical Networking - Friday, 22 September 2006.
The cost savings to be realized in reducing or eliminating amplifier hut sites should not be underestimated. CAPEX, EFI&T and OAM burden all stand to be cut. Consider, too, that leased office space may run an enterprise as much as $1,000 to $2,000 per month when power and air conditioning are included. Elimination of just a single mid-span amplification site along a 200-kilometer link could save the enterprise up to $100,000 over a five-year period. The economic argument for Raman amplification in enterprise networking is strong.
In context of storage services, the ability to lengthen the distance between data vaults rates is an even more compelling benefit. To gain the protection they want (and governments more and more frequently require), enterprises must be able to put more distance between their primary and backup data centers. Raman amplification cost-effectively delivers that capability.
