Fiber T1 Modem (and Ethernet Extender)

The FTM is the industry's most advanced and cost effective fiber-optic T1 modem. Installed in pairs, it extends a T1 link over a distance of up to 91 miles (!) or, if short of fibers up to 25 miles over a single-fiber-strand. However the main advantage of the FTM over virtually any other product available is the Fast Ethernet connectivity that it provides over the same link, allowing the user to connect its IP traffic (at full bandwidth!) over the same infrastructure- at no additional cost at all.
