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.
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.
