Applications
Typical applications include linking remote
terminals or printers to host computers, tail circuits to existing
multiplexers and extending data communications links. Fiber optic modems
are also ideal for connecting data communications devices in harsh
manufacturing or outdoor environments where EMI or RFI interference,
ground loops and lightning are prevalent.

Description
Pocket Rocket modems are designed for local
and campus networks up to distances of approximately 5 km multimode and 30
km single mode. Distances can vary depending on the size and type of fiber
optic cable, number of connections and type of fiber optic connectivity
device(s) used in a given network.
The TC1000 is low in price and high in
reliability. It is plug compatible with RS-232 interfaces and will
transmit asynchronous data at speeds up to 19.2 Kbps. It supports both
single mode (1300/1550nm) and multimode (850/1300nm) formats. Fiber optic
connectors are ST or FC. An extreme temperature version (-20°C to 70°C),
Model TC1000T, is also available.
Electrical connectors are DB25 female. It
is DCE/DTE switchable. For most applications, the TC1000 derives power
though any of the standard EIA control signals (pins 4, 8, 20) or positive
voltage line (pin 9). An external power supply (115/230VAC) may be
required when signal power is not adequate to drive the TC1000.
