The Model 9271
RS-232 Fiber Optic
Auto Powered Line Driver
features a standard DB9 interface for maximum performance and
reliability of data transmission over glass fiber, eliminating the
need for serial to nine-pin adapters. In addition, it brings
effective data communications to manufacturing environments. It can
be installed in applications requiring very high data transmission
rates, offers resistance to Electromagnetic Interference (EMI), and
isolation from lightning-induced current surges and ground loops.
The unit employs an RS-232 data interface, can achieve 115.2 kbps
asynchronously and operates in either half- or full-duplex modes
over dual fibers up to 2 km in length.
The Model 9271's ability to take/direct data from/to this interface
without any conversion eases implementation. A highly flexible
solution, the Model 9271 has been optimized for 62/125 fiber cables,
and is compatible with other sizes as well. It features
industry-standard ST cable port connectors, plus a DTE/DCE switch to
reverse Pins 2 and 3 of the RS-232 connector to accommodate
equipment with different data output configurations.
Operating current for the Model 9271 is derived from the transmit
data line, with a power budget of 12 dB when using 62/125 cable. For
applications requiring a dedicated power source, the unit can be
ordered with a wall AC-DC power supply (available as the Model
The Model 9271 incorporates clips in the outer casing so that the
unit can be securely attached to a DIN rail, wall, table or desk in
an organized manner.
