NEW YORK -- Metromedia Fiber Network, Inc. (MFN) (Nasdaq:MFNX), the leader in deployment of optical IP Internet infrastructure within key metropolitan areas domestically and internationally, together with its subsidiary AboveNet Communications, Inc., can now offer customers their own dedicated, dark fiber network infrastructure connecting them to the Internet.

Called Virtual ISX, this is the first optical Internet connection to leverage the virtually unlimited bandwidth and fixed cost of dark fiber with a scaleable IP backbone, eliminating the bandwidth constraints typically encountered with traditional networks. Virtual ISX uses Wavelength Division Multiplexing (WDM) technology over dark fiber so customers can grow and scale their Internet bandwidth on demand. Virtual ISX supports multiple-gigabit-per-second connections without the need to change the infrastructure, and dark fiber can accommodate up to multi-terabit-per-second capacity for future needs.
