Optic modem for T3 extensions
Optically Extend T3
This is the
solution for the Telco Demark in the wrong place or even the wrong building.
When you need to tie building communications together at the T3 - DS3 level
the T3 DS3 Fiber Optic modems will let you extend D3 T3 Demark .
Model TC1680 T3 Fiber Optic modem
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.
The TC1680 T3 E3 Fiber Optic Modem provides a high speed point-to-point data link between two DS3 or G.703 conforming devices. User benefits include easy installation and 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 transmits standard T3 (44.736M) or E3 (34.368M) signals at distances up to 100km. It 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.
Diagnostics include built-in self test, link verification test (local and remote loopback), and a dry contact for remote alarm. Sixteen LEDs are provided to help installation and troubleshooting. These LEDs indicate power, alarm status, T3/E3 signal loss and optical status. Four DIP switches, accessible from the front panel, control settings for the built-in signal generator, local & remote loopback, and general alarm.
Power redundancy is standard, optical redundancy is optional. Both power and optical redundancy systems include an automatic switchover feature to insure virtually uninterrupted operation. The TC1680 is available multimode (1300nm) or single mode (1300/1550nm) and in rackmount (TC1680R) or stand alone (TC1680S) versions. The TC1680R PC card version fits into TCRM191 and TCRM195 card cages.
The TC1680 is compatible with all popular types and sizes of fiber optic cable. Fiber optic connectors are ST or FC. The electrical connector is BNC. Input power is 12VDC, optional 24VDC, -48VDC or 115/230VAC with an external power cube. An extreme temperature version (-20ºC to 70ºC), Model TC1680T, is also available.
