Fiber Optic Modem

9PFLST, 232FLST

These port-powered ﬁber optic modem allows two RS-232 serial devices

to communicate transparently over longer distances and with greater

reliability. The inherent immunity of ﬁber optic protects data from line

surges, spikes and ground loops.

They transmit RS-232 data, full or half duplex, over two ﬁbers at distances

up to 4 km (2.5 mi) and data rates up to 115.2 kbps.They have a DCE

female serial connector and multi-mode ST ﬁber connectors. TD, RD, and

RTS/CTS handshake lines are supported.

The modem is powered from the RS-232 data and handshake lines. A

power jack is provided for connecting an optional +12 VDC supply (not

included) for use with low powered ports such as laptops and PCs.

Fiber Optic Benefits

Fiber optic cable carries serial data up to 4 kilometers (2.5 miles), much farther

and reliably than conventional copper lines.

Power surges, spikes and groupd loops are created by electrical equipment,

by nearby lightning strikes, and from other sources. They are easily picked

up by copper data lines and transmitted to connected devices, garbling data

communications and damaging equipment.

However, fiber optic data transmission uses light in glass fiber cable as a

communication medium. Being inherently non-electric, fiber optic cable will

notpickupnoiseandprovidesthemostreliablesystempossible–ideal

for spanning areas with severe interference, such as near heavy electrical

equipment, welding or radio transmissions. It does not transmit power spikes

or surges and prevents ground loops by not providing a conductive path for the

ground.
