Safety instructions
∂The core part of OTX 1310-10 is a ESDlaser.
∂Please obey the operation rule strictly and carefully when disassemble and assemble. The wrist belt and
the union suit should be also grounded.
∂All electric power and optical transmitter should be given a good grounding connection.
∂The electric power of the optical transmitter should be 90…265VAC and a regulated AC power is
suggested.
∂The RF signal must not be connected until the optical transmitter arrives at it’s normal working point. The
amplitude of the RF signal should follow the instructions in the test report of the optical transmitter. An
abnormal RF signal power will overload and damage the laser.
∂The optical transmitter should be stored in a ESD protection environment (such as a ESD protection
container) and cannot be stored with corrosive cargo. The store temperature should be within -20℃ ～
+50℃.
∂Forced cooling should be added when multiple optical transmitters are mounted on the same rack.
∂Please don’t open or repair any part of the transmitter, otherwise the producer don’t pay the fiddler.
∂Eyes may be hurt if you watch the optical outputdirectly.
∂The heat elimination hole should not be blocked. The transmitter need good airing to work properly.
∂The optical output should be covered with our dust-proof if the transmitter don’t work for a long period.
∂When failure occurs,the transmitter should be sent to the producer in time. And please don’t open or
repair any part of the transmitter, otherwise the producer don’t pay the fiddler
Direct eye exposure to laser beam may cause physical damage

1. Description
The OTX 1310-10 is a high performance optical transmitter, based on ORTEL and AOI transmission
technology. The optical transmitter has following functions:
∂AGC/MGC mode
∂Low noise DFB laser
∂Adjustable OMI
∂SNMP (Simple Network Management Protocol) for administration and monitoring
∂
Furthermore, it has two redundant plug-in power supply modules.
OTX 1310-10 is used for long-distance optical fiber transmission of television TV signals. It uses a high-
performance DFB laser and RF power automatic processing technology, which assures excellent performance. It
can be used for large-scale HFC networks.

3. Installation
Check and make sure that the equipment, enclosure and electric power have a good grounding connection.
Check and make sure that the electric power is within 90…265VAC.
Connect the optical fibre with the optical output. Make sure the connection is cleanded before use.
Connect the electric power and turn on the power switch.
The power supply LEDs are displaying the working status.
Touch the display choice button, check the index such as the output laser power, the laser’s offset current,
temperature, cooling current, etc.
If the status is normal and the RF input level matches the requirements, connect the RF signal to the RF
input.

5. Troubleshooting
General Recovery Processing
Failure Phenomenon Reason Settle Method
LED does not work no electric power or fuse
burn out Power ON or Fuse replace
LED is black Temperature maybe too
high Force Cooling
The measurement of the
LED displays the status is normal,
but there is no laser output or the
output does not match the display
output laser power is not
correct.
Ring flange or test jumper
connection is dirty.
Change the output laser power sensor
Clean the connection
Change the test jumper
Test jumper connection
mismatches.
Both, the laser power of the
optical transmitter and receiver
are normal, but there is no RF
output signal at the receiver or the
output level is too low.
No input RF signal or RF
connection is not good.
Check the RF level and reconnect the
RF input.
If you checked everything mentioned above and the failure phenomenon still exists, the transmitter should be
shut down immediately. Please contact the producer directly.
