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.
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.
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.

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.
