Installing the OP-131Tx Optical Transmitter
4.1 Receiving and Inspecting
As you unpack your unit, inspect the shipping container and equipment for damage. Save the
shipping material for future use. If the container or the equipment is damaged, notify both the
freight carrier and us.
CAUTION: To protect yourself from potential injury and to protect the
equipment from further damage, do not perform any
operational tests if the equipment appears to be damaged.
4.2 Precautions
Heed the following precautions when working with the OP-131Tx.
Warning
Read the installation instructions before connecting the
system to the power source.
Warning
The plug-socket combination must be accessible at all
times, because it serves as the main disconnecting device.

4.3 Mounting the OP-131Tx
4.3.1 Mount the OP-131Tx in a cabinet
To mount the OP-131Tx in a standard 19-inch equipment cabinet:
1. Place the unit in the cabinet.
2. Use four mounting screws to attach the mounting ears on the front panel to the cabinet.
3. Reliably ground the equipment, the ground terminal is on the rear panel.
4. Visually inspect each key (button) on the front panel to ensure that it is not trapped under
the edge of its hole. If a key is trapped, tap the key to enable it to move freely.
4.3.2 Connecting the RF Cables
Verify the type of RF input F connector according to the ordering information, and then
connect with the matched RF cable.
4.3.3 Connecting the Optical Fiber Cables
OP-131Tx has one output optical connector.
DANGER: The fiber carries invisible laser radiation. AVOID DIRECT
EXPOSURE TO BEAM. Never operate the unit with a
broken fiber or with a fiber connector disconnected.
1. Verify the optical fiber connector type is matched with OP-131Tx according to the ordering
information.
2. Verify that the fiber cable connector has been cleaned properly. If the fiber cable connector
needs to be cleaned, follow the cleaning procedure outlined in “Cleaning Patch Cord or
Pigtail Fiber Optical Connectors”.
3. Verify that the OP-131Tx optical connector has not been exposed to any contamination.
NOTE: Any contamination of the optical connector can significantly
degrade optical link performance. This degradation will most
likely manifest itself as poor signal-to-noise (SNR) performance.
4. Note the key characteristics of the mating connectors and align them accordingly.

4.3.4 Connecting the Ethernet Cable
You can connect the OP-131Tx to your TCP/IP network in order to monitor and control the
transmitter remotely. After you complete the installation procedures described in this chapter,
you can use a network management system (NMS) to monitor and control the OP-131Tx.
To connect the OP-131Tx, you must use a shielded and grounded Category 5 Ethernet cable.
To connect the Ethernet cable:
1. Connect an Ethernet cable to the transmitter’s RJ-45 Ethernet port and to your TCP/IP
network. The Ethernet port is on the built-in transponder of transmitter.
2. Verify that the green Link LED is illuminated, indicating that there is a connection.
4.3.5 Connecting Power
OP-131Tx uses AC220V power supply. Follow the power connection procedure below.
It can equip two 220V power supplies that require input voltage from 110 to 265 VAC, at 50
to 60Hz single phase. The AC power plug is located on the rear panel.
Connect the power; it takes about 60 seconds for all systems to operate.

IP address of 0.0.0.0 and 255.255.255.255 don’t exist. SNMP Trap does not send to these two
addresses.
community
This command configures the read-only group name and read-write group name. “Group
name” is the concept of SNMP agreement like the password. Use the command “community
ro” to configure the read-only, and “community rw” for the read-write. For example, input
“community rw public”, “public” is the read-write group name. The group name for read-
only and read-write are both “public” as the equipment default setting from factory.

5.4 Remote Monitoring: SNMP
LAN communication interface
Adopt RJ45 standard connector, the pin definitions as follow:
1: TX+
2: TX-
3: RX+
4: No Connect
5: No Connect
6: RX-
7: No Connect
8: No Connect
A: Green indicator flashing means that the LAN port is sending data.
B: Yellow indicator means that the network connection is normal.
SNMP basic background
Simple Network Management Protocol (SNMP) is an application layer protocol. It
makes the management information between network devices exchange easier. It is part of
the TCP / IP protocol group. SNMP enables the end-users to manage network performance,
find and solve network problems, and arrange for future network upgrades.
Management Information Base (MIB) is the organized hierarchical information set. Use
SNMP to visit these MIB. They are composed of manageable information, and identified by
the object identifier.
SNMP
Transmitter configuration of network communication
When the transmitter initial work, the IP address and gateway are in the default state,
you need to configure them. The configuration of initial state can be achieved through the
RS-232 interface or the front panel keys. Other configurations see our <Network
Management Instructions>.

6.0 Maintenance and Troubleshooting
6.1 Cleaning Fiber Optic Connectors
DANGER: The fiber optic connector carries invisible laser radiation
while working, so should avoid charged operation.
Dirty optical connectors are the leading source of poor performance in a broadband optical
fiber network. Dirty optical connectors lead to optical signal loss and reflections, which in
turn can seriously degrade signal-to-noise (SNR) performance and, in some cases, distortion
performance. We recommend that you clean all mating fiber connectors before connecting
them to an optical transmitter.
In addition, if you suspect that the optical connector of OP-131Tx may have been exposed to
contamination (by a dirty fiber cable connector, for example), you should properly clean the
optical connector before connecting the optical fiber.
CAUTION: Improper cleaning of an optical connector can do more
harm than good. Never spray a clean-air product onto the
surface of an optical connector. Spraying air onto an
optical connector can cause condensation on the connector
surface, leaving water spots and trapping dust. Failing to
wipe a connector on dry lens paper immediately after
wiping on paper wet with isopropyl alcohol can also lead
to condensation on the connector. Using low-grade
cleaning paper or other cloth to wipe an optical connector
can leave microscopic fibers on the optical connector
Surface.
6.1.1 Cleaning Patch Cord or Pigtail Fiber Optical Connectors
To clean optical connectors, we recommend using a fiber optic connector cleaning cartridge
(such as NTT Cletop). If a cleaning cartridge is not available, follow these steps.
To clean the optical connector of a patch cord or pigtail:
1. Fold a piece of unused dry lens cleaning paper twice, for a four-ply thickness.
2. Use a drop of high-grade isopropyl alcohol to wet part of the paper.
3. Lay the connector on the lens cleaning paper with the tip touching the paper.
4. In one continuous motion, pull the connector from the wet part of the paper to the dry part.
