OP-OR124RJ Four-way Return Path Optical Receiver
1. Summary
OP-OR124RJ type is the upgrade product of OP-OR124R type. Can automatically
set or manually adjust the input signal on/off function (RFOG), greatly curb the
overall network noise. Add optical AGC function, keep the output constant when the
signal changed in a wide range; and add microcomputer condition monitoring circuit
and front panel display screen, support standard class II network management
transponder.
2. Features
Optimized circuit design, SMT process production, optimized signal path, make
the photoelectric signal transmission more smooth.
SCM control working status, LCD displays the parameters, convenience and
intuitive operation, and stable performance.
Excellent AGC characteristic, keep stable output level in the received optical
power range -10～0dBm.
Can switch to burst mode, greatly reduced the link aggregation noise; with single
way RF shut off function, the localization diagnosis of ingress noise is easy.
Support dual power supply hot backup mode and four-way mixed output mode.
Reserved data communication interface, can connect with class II network
management responder, access to network management system.

Working Mode
Description
Normal：AGC/MGC
1. Normal is the general working mode.AGC or MGC optional.
2. Select AGC: turn on the optical AGC function, the output level will not vary
with the change of received optical power, its adjustable range is 10dB.
3. Select MGC: turn off the optical AGC function, the output level will vary with
the change of received optical power, its adjustable range is 30dB.
RF OutPut SWx：ON/OFF
Under the Normal mode, can forcedly shut off the RF signal by RF OutPut
SWx：ON/OFF menu. There is no this menu under the RFOG mode.
RFOG
1. RFOG is the burst working mode. Automatic turn off the optical AGC
function.
2. Under the RFOG mode, there is RF signal output only when input the return
optical signal; otherwise, there is no RF signal output.

8. NMS setup instructions
If users configured the network management responder, need to do the following
settings:
Responder IPsetup instruction:
Network management directly modify:
1. Default IP is 192.168.1.168，default gateway is 192.168.1.1，default subnet
mask is 255.255.255.0
2. Connect the computer and responder (can be direct connected), and change the
computer IP to 192.168.1.XXX (XXX is any number from 0 to 255 except
168); start upper computer network management software, then search the
device and log in.
3. Right-click device icon and choose modify the device IP.
4. Enter new IP address, gateway and subnet mask.
5. Click modify，then exit, it is done. There will show new IP address and
gateway on operational logbook.
6. Reboot the responder, the new IP take effect (Click the reboot button in the
network management software or power on again)

9. Clean and maintenance method of the optical fiber active
connector
In many times, we misjudge the decline of the optical power or the reduce of
optical receiver output level as the equipment faults, but actually it may be caused by
the incorrect connection of the optical fiber connector or the optical fiber connector
has been polluted by the dust or dirt.
Now introduce some common clean and maintenance methods of the optical
fiber active connector.
1. Carefully pull off the optical fiber active connector from the adapter. The optical
fiber active connector should not aim at the human body or the naked eyes to
avoid accidental injury.
2. Wash carefully with good quality lens wiping paper or medical degrease alcohol
cotton. If use the medical degrease alcohol cotton, still need to wait 1~2 minutes
after wash, let the connector surface dry in the air.
3. The cleaned optical fiber active connector should be connected to optical power
meter to measure output optical power to affirm whether it has been cleaned up.
4. When connect the cleaned optical fiber active connector back to adapter, should
notice to make the force appropriate to avoid the ceramic tube in the adapter
crack.
5. If the output optical power is not normal after cleaning, should pull off the
adapter and clean the other connector. If the optical power still low after cleaning,
the adapter may be polluted, clean it. (Note: Be carefully when pull off the
adapter to avoid hurting inside fiber.)
6. Use the dedicated compressed air or degrease alcohol cotton bar to clean the
adapter. When use the compressed air, the muzzle of the compressed air tank
should aims at the ceramic tube of the adapter, clean the ceramic tube with
compressed air. When use degrease alcohol cotton bar, carefully insert the
alcohol cotton bar into the ceramic tube to clean. The insert direction should be
consistent, otherwise can not reach ideal cleaning effect.
