Features

The TC1901 "Quick-Talk" Fiber Optic Phone/Analog Extender can turn a fiber optic network into a voice network simply by plugging in a telephone set.

Quick-Talk is typically used to extend phone service or 2/4-Wire analog 600 Ohm links to remote sites over a fiber optic circuit. For example, a user can extend a secured phone link (for telephone, fax or dial-up modem) to a remote site via the fiber optic up to 80 Km away.
