Warning
UNINTENDED EQUIPMENT OPERATION Do not connect a 140 NRP 312 01
single-mode fiber converter module to a 140 NRP 312 00 multi-mode
fiber converter module. Failure to follow these instructions can
result in death, serious injury, or equipment damage.
140 NRP 312 00/01 fiber converter modules are an alternative method
to using a dual-ring switch
(DRS) to provide fiber optic communications in a Quantum EIO
system. You can install 140 NRP 312 00/01 modules on Quantum local
and RIO drops to:
l extend the total length of the Quantum EIO network (RIO drops in
separate areas of a factory that are more than 100 m apart)
l improve noise immunity
l resolve possible grounding issues when using different grounding
methods is required between 2 buildings You can connect a 140 NRP
312 00/01 module to any 100Mbps-based Ethernet module on a Quantum
rack to extend the transmission distance. Examples:
l You can connect a 140 NRP 312 00/01 module to a 140 CRP 312 00
RIO head module or a 140 CRA 312 0• RIO adapter module in a Quantum
EIO system.
l You can connect a 140 NRP 312 00/01 module to a 140 NOC 780 00
DIO head module to manage DIO devices. There are 2 models of fiber
converter modules, each supporting one type of fiber cable:
l 140 NRP 312 00 supports multi-mode fiber cable.
l 140 NRP 312 01 supports single-mode fiber cable.
For details on other fiber converter modules and how they operate
within Quantum and M340 networks, refer to the 140 NRP 954 00/01C
Fiber Optic Repeater Modules User Guide and the BMX NRP 0200/01
Fiber Converter Module User Guide.
Introduction
140 NRP 312 00/01 fiber converter modules have 2 copper ports and 2
fiber ports. The fiber ports, in both multi-mode and single-mode
modules, use LC-type connectors. One fiber port is used as the
transmitter signal (Tx), and the other fiber port is used as the
receiver signal (Rx). There are 2 models of fiber converter
modules, each supporting one type of fiber cable: 140 NRP 312 00
supports multi-mode fiber cable. 140 NRP 312 01 supports
single-mode fiber cable.
