1. Introduction
OR303 optical receiver mainly used in trunk and lateral optical fiber network, it can supply high quality Videos and data service. It is full-featured product, has excellent index and high reliability, and is a high-performance low-cost optical receiver., with excellent CNR,CSO, CTB index, as well as efficient photoelectric conversion box matching functions to ensure high quality signal transmission, can for network upgrades at any time
This product adopts steel cable hoisting type die-casting waterproof shell, it has good sealing quality and good heat dispersing performance, as well as completely shield against electromagnetic interference effects, it can be used in various occasions.
We have three optical modules that make up three different models
ORNU1004:-15~0dBm optical control AGC, output level keeps unchanged.100dbuv
ORNU1005:-10~0dBm optical control AGC, output level keeps unchanged.106dbuv
ORNU1006: without optical control AGC,-2dBm input power output level more than 102dbuv
2. Characteristic
-Use high efficiency, wide voltage switching power supply
-RF channel operating bandwidth can be extended to 1002Mhz/1218Mhz..
-Real-time monitoring of optical input power, with LED status indicator
-Three optical modules optional can be wide range of optical power input

6. Installation and Operation
1) Installation
Installation consists of splicing the service fiber cable to the transportation fiber, installing the housing and electronics on the messenger strand, applying power, and placing the unit in service.
It is recommended that the equipment has been correctly configured, and tested on the bench.
Splicing Fiber
The service cable can be spliced to the transportation cable at any time during the node installation. Splicing does not need to coincide with the installation of the housing.
Fusion splicing is recommended because it has low insertion loss and is the most reliable method. The splicing should be done by a technician experienced in splicing fiber.
Warning! To avoid possible injury to personnel or damage to the equipment, remove 60/220Vac power from the system before you install the node.
2) Operation
Test output level using a signal level meter:
-For 0dBm input, tap output:
The receiver output (output1) is above 98dBuV; output2 is 12dB less than output1.
-For splitter output, output1 & output2 are both above 94dBu.
Troubleshooting
Only the following steps are allowed for users to solve simple failure. If the fault remains, please contact our company or the supplier. Do not repair the equipment or open the case privately by yourself.

Trouble
|
Settlement
|
|
RF output level is low.
|
1. Test input power of receiver, and appropriately increase input level of transmitter.
2. Clean terminal surface of FC/APC connector. 3. Test the voltage of amplifier modules, it should be 24±0.3V. |
|
Television image has snowflakes, but output level is normal.
|
Increase input level of transmitter, or improve signal quality.
|
|
Television image has twills.
|
Reduce input level of transmitter, or improve signal quality.
|
|
Having no RF output signal.
|
1. Make sure if the power supply works correctly.
2. Make sure if any plug of the power supply is loose. 3. Measure input (receiving) power of the receiver. |
