CHAPTER 1
DESCRIPTIONAND SPECIFICATION
1.1 INTRODUCTION
Phoenix Digital’s family of RockwellAllen-Bradley Data Highway Plus and Remote I/O
(DH+/RIO) fiber optic modules provide the most advanced, comprehensive, state-of-the-art
fiber optic communication capabilities on the market today. Phoenix Digital’s DH+/RIO fiber
optic modules are available as standalone, panelmount modules with integral 120/220 VAC, 24
VDC, or 125 VDC power supplies (Optical Communication Modules... OCMs), 1771 plug-in
modules (Optical Communication Modules... OCMs), 1746 plug-in modules (Optical Link Cou-
plers... OLCs), and 1756 plug-in modules (Optical ControlLogix Modules... OCXs). These
fiber optic modules translate hardwire networks into an optical network medium, transparent to
the communication protocol and configurable for distribution by the user in ring, bus, star, tree,
or point-to-point network installations. Fiber optic network options include features not found
in even the most expensive communication network installations; on-line diagnostic monitoring
with high speed self healing communication recovery around points of failure (Fault Tolerant),
in-line signal strength monitoring with annunciation of impending communication failures (Fault
Predictive), interactive diagnostics to locate fault and impending fault conditions (accessible by
the user program), and wavelength selection for matching fiber media characteristics. Phoenix
Digital makes all of this possible through application of its patented self healing communication
switch and advanced optical measurement technologies.
The following table provides correspondence between Phoenix Digital fiber optic module Model
Numbers and RockwellAllen-Bradley network compatibility. The user should check the Model
Number label located on the side of the fiber optic module cover to verify network interface
compatibility.

The ultra-high speed, self healing communication technology on each fiber optic module will auto-
matically redirect network traffic around points of failure (wrapback communication). In a failed
condition the fiber optic communication network will self heal around a fault by redirecting data
communications around the point of failure. This is accomplished by wrapping back network com-
munications at the communication nodes on either side of the point of failure, through the use of a
high-speed, combinational wrapback communication switch (hardware pass-thru, non-software in-
teractive) built into the front-end optical interface of each Phoenix Digital fiber optic module.
Figure2 illustratesatypical fiberoptic DH+fault tolerantring networkconfiguration. Inthis configu-
ration, the fiber optic modules must be connected ChATransmit to ChAReceive, ChATransmit to
ChAReceive, etc., around the ring (counter-clockwise in Figure 2); and Ch B Transmit to Ch B
Receive, Ch BTransmit to Ch B Receive, etc., around the ring (clockwise in Figure 2). Diagnostic
monitoringcircuitry ateach modulewillcontinuously monitorthe integrityof thecommunication car-
riers present at the receive data inputs of each communication channel. This high speed combina-
tionaldiagnosticmonitoring circuitry willmonitor and detectcommunication failures incarrier sym-
metry, jitter, amplitude, and babble. In the event a fault condition is diagnosed on the network
(Figure 2: Node 2/Channel B receiver and Node 3/ChannelAreceiver) the fiber modules detecting
the failure (Nodes 2 and 3) will immediately redirect communication around the point of failure, the
opposite way around the ring. Essentially, the network dynamically reconfigures to form a new
communication path from Node 2 to Node 3, away from the point of failure (the long way around the
network),thus insuringcommunication networkcontinuity andfault isolaton. Inaddition toproviding
networkfault tolerance, PhoenixDigital’sfiberoptic modulesenable maintenancepersonnel tolocate
faultconditions(remote statusmonitoring), add/delete nodes,and splice/terminate/replace mediaon-
line,without disruptingnetwork communications.
Communication continuity will be unconditionally maintained by the fiber optic modules in the
event of either node or media failure. When the source of the network failure is corrected, the
fiber optic modules will automatically restore the communication network to its original traffic pat-
terns.

1.2.2 FAULT PREDICTIVE COMMUNICATION (850 nm and 1300 nm
MULTIMODE ONLY)
Phoenix Digital’s Fault Predictive CommunicationTechnology provides diagnostic monitoring and
detectionof impendingcommunication failuresresultingfrom gradualdegradation ofthe communica-
tionlink itself. Phoenix Digital’sfiber opticmodules monitor impendingfault conditionsby continu-
ously measuring the actual in-line signal strength (optical power) of the data comunications at each
receive input on the module. The fiber modules continuously compare these actual in-line measure-
ments to preset optical power reference thresholds, which are normalized to power levels where
valid network communications will still be assured, but impending communication failures can be
accurately predicted. If the actual in-line data communication signal strength degrades below these
power thresholds (resulting from one or more sources of link degradation) the fiber modules will
automaticallydetect andannunciate theimpending failureconditionsviavisualindicators onthe front
of the module. Phoenix Digital’s fiber optic modules also provide User ProgramAccessible, Inter-
activeDiagnostics(1771, 1746,and 1756 Plug-InFiber Modules) andHardwired Diagnostic Ouputs
(Standalone, Panelmount Fiber Modules) for remote monitoring, detecting, and locating of impend-
ing fault conditions (remote status monitoring). In addition, the fiber optic modules provide a linear
DC voltage representation (analog) of the actual in-line signal strength (normalized for a 0 to +3.5
VDCrange)for moreprecisemonitoring ofcommunicationlink status(on-lineoptical powermeter-
ing). Thus,communication linkstatus iscontinuouslymonitoredandimpending failureconditions are
annunciatedby the fibermodules beforethecommunication failureactually occurs,enablingmainte-
nance personnel to perform Predictive Maintenance on the fiber optic communication network at-
large. (The Impending Fault Monitoring feature is available only on 850 nm or 1300 nm
multimode fiber optic modules with the “-D” Diagnostic Option.)
1.2.3 WAVELENGTH SELECTION
Phoenix Digital’s fiber optic modules provide five options for wavelength selection. The
economical 850 nanometer multimode wavelength may be selected for data communication
networks with less than 12,000 feet (3,650 meters) between communication nodes. The higher
performance 1300 and 1550 nanometer multimode wavelengths may be selected for longer
distance applications, extending communication distances between nodes to over 6 miles (10
kilometers). For maximum distance, the ultra-high performance 1300 and 1550 nanometer
singlemode wavelengths may be selected, extending communication distances to over 16 miles
(25 kilometers) between communication nodes!

(1) J1 Connector Orientation on the front of the OCM module is top to bottom, Pin #s 1 thru 8 respectively.
(All unused J1 connector screw terminals should be fully seated.) See Figures 3 and 4 for J1 Connector
Designations.
(2) ChannelAand Channel B RSS provide DC voltage outputs proportional to the optical receive signal strength
of fiber optic channelsAand B respectively. (Available only on fiber optic modules operating on the 850nm
or 1300 nm multimode wavelengths. See Interactive Diagnostics in Section 1.3.3 for detailed information.)
(3) Each end of each hardwired DH+ or RIO network stub (wire connection made to the OCM J1 connector)
must be terminated with either an 82 ohm, 5%, 1/4 watt resistor (230 K baud and Remote I/O “Extended
Node” networks), or a 150 ohm, 5%, 1/4 watt resistor (57.6 K baud and 115.2 K baud networks, excluding
“Extended Node” RIO networks).
A150 ohm, 5%, 1/4 watt termination resistor is internally provided in every OCM module. This resistor is
connected across Serial 1 and Serial 2 by jumpering together pin #s 7 and 8 on the OCM J1 connector
(Factory Default). If the OCM is located on either end of the hardwired network stub (connected to the
OCM J1 connector), and a 150 ohm termination resistor is required, then a termination jumper must be
provided on the OCM J1 connector between pin #s 7 and 8. If a 150 ohm termination resistor is not required
at the OCM location then the jumper should not be installed. If an 82 ohm resistor is required at the OCM
location then this resistor must be installed externally, on the OCM J1 connector, across J1 connector
pin #s 6 and 7. In this case, J1 connector pin #s 7 and 8 should NOT be jumpered together. (An external 82
ohm resistor is provided with every OCM-DPR.)
If the OCM is used as a fiber optic repeater and is not connected to any Rockwell devices, then it should
have the J1 Connector Local Interface disabled. See Interactive Diagnostics in Section 1.3.3 for more
information.
(4) All of the DH+ and RIO devices on each hardwired nework stub must be interconnected Serial 1 to Serial 1
and Serial 2 to Serial 2. Cross-connecting Serial 1 to Serial 2 will cause communication failures. Consult
Rockwell DH+ and RIO Network Installation Guidelines for more information on correct network
installation and wiring procedures.
