If you only want 1gig, then if the SP provides it, won't it be cheaper to simply get a 1gig circuit from them that hands off to you on a GigE port rather than pay for all the various higher spec equipment that you'd otherwise require? Paul.
Yes, a carrier provided lit service (wavelength, EoMPLS) would obviously be less expensive than leasing dark for a single 1GE channel (especially for longer spans), but I'm assuming OP has already considered this and is going with a dark fiber option for one of the following reasons: A) Expected rapid growth in transfer volume, wherein a dark fiber solution provides the OP with the flexibility to rapidly upgrade to either a multi-channel xWDM 1GE, single channel 10GE, or xWDM 10GE solution immediately, as opposed to a lit solution where he would be restricted by the provisioning time line of the carrier (dark quickly becomes a more attractive solution than lit services as bandwidth needs increase) B) Specific business requirements (ie security concerns) that preclude the usage of 3rd party's network/transmission gear from carrying traffic deemed 'sensitive', 'confidential', etc. You fill in the blanks. The idea is laughable to many operators, but sometimes a board's ideal model of data security is not exactly in line with business and technical realities (Usually this means money in your pocket). -- Cheers, Kevin ================================================================ :: :: Kevin Hodle | http://www.linkedin.com/in/kevinhodle PGP Key ID | fingerprint 0x803F24BE | 1094 FB06 837F 2FAB C86B E4BE 4680 3679 803F 24BE "Elegance is not a dispensable luxury but a factor that decides between success and failure.
