TC1680
T3/E3 Fiber Optic Modem (Rackmount & Standalone)

The TC1680 T3/E3 Fiber Optic Modem connects two DS3 or G.703 conforming devices. User benefits include built-in self/link test, easy installation & troubleshooting, high reliability, low power consumption (less than 5 Watts), virtually no jitter (because the signal is re-timed at the remote end) and overall small size (1.4" X 7.1" X 9.8").

The TC1680 is ideal for 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 metallic media T3/E3 multiplexers.

It transmits standard T3 (44.736M) or E3 (34.368M), is compatible with B3ZS (T3) and HDB3 (E3) coded data streams and conforms to applicable standards including ANSI T1.102-1993, TR-TSY-000499 and CCITT G.703.
