The Model TC1680, T3/E3 Fiber Optic Modem provides a point to point high speed data link between two DS-3 conforming devices. The distance between adapters can be extended up to 30 km with a laser transmitter option. The T3/E3 Model TC1680 adapter is especially valuable for extending your DS-3 circuits to another building on the premises.
Besides distance, a fiber optic link offers more advantages than coax for DS-3 Data. A fiber cable has a characteristics of high bandwidth, low loss, less signal distortion, and high noise immunity. It can provide user with a clean, secure link and helps eliminate problems associated with coax cable such as noise, crosstalk and power surges.
The Model TC1680 also is a repeater for DS-3 data. Signals received from both fiber and coax port inputs are retimed and reconstructed to reduce jitter and distortion.

Typical Application (Application Questions)
The TC1680 is ideal for most T3/E3 connectivity applications up to distances of 100km. Typical applications include replacing coaxial cable with fiber, extending the point of presence from Telco demarcation points and ATM nodes, transmitting digitized video or linking T3/E3 multiplexers.
