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
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.
