C-CORP 1310 Optical Transmitter Direct Modulation

C-CORP 1310 Optical Transmitter Direct Modulation is a strong technical professional equipment, its installation and commissioning must be carried out by professional and technical personnel and carefully read the manual before operation, so as not to damage the equipment due to wrong operation, or cause accidental injury to the operator.

C-CORP 1310 Optical Transmitter is designed according to CATV standard. It modulates CATV RF amplitude signal into 1310nm optical signal and then transmits it to optical node in HFC network through single-mode optical fiber. It is mainly used for TV signal medium-sized network transmission.

When the device works, the optical fiber adapter which is located in the rear panel cannot be visible in the optical fiber adapter. The optical signal output port is not aligned with the human body, and the optical output port cannot be looked directly at the eye, so as to avoid permanent damage to the human body and the human eye (the laser can cause blindness)!!!

Before setting up the equipment, the operator should ensure that the system rack and power sockets grounding terminal has a reliable grounding (grounding resistance should be less than 4Ω), in order to avoid damage to the static laser devices and to prevent the body from electricity shock.

In order to ensure long-term stable operation of the equipment, it is recommended for the user to configure a dedicated AC regulated power supply. It is recommended that this is to be used with uninterrupted power supply (UPS) system (equipment ideal working environment temperature is 25 degrees Celsius) and it is recommended that there a good air-conditioning to improve the working environment of the equipment.

1.）Product Structure

Product Overview This C-CORP 1310 Optical Transmitter Direct Modulation is designed to meet the requirements of a front-end computer room equipment intensive installation, development and design of a CATV integrated node. The double power supply hot backup structure feature is dedicated to the server and can effectively improve the reliability of the system with the intelligent temperature control system controlled by the microcomputer. The device is equipped with a standard RJ45 network communication interface (built-in responder), 10/100Mbps adaptive rate, can easily achieve remote network management centralized monitoring, is to build a high-performance two-way HFC broadband network of the first choice. Can be equipped with modules: dual module combination or single module independence.
Product Feature
* Compact design, 1U rack can be achieved dual module integration.
* Configuration flexible, on-demand collocation.

4.）Maintenance and Troubleshooting

This C-CORP 1310 Optical Transmitter Direct Modulation has been tested at the factory with careful commissioning. Please check the following table when the control is not working properly, if found with machine malfunctions, please contact our sales department or sales department. Do not reboot to repair, otherwise the warranty will be void.

Issue	Cause	Solution
After the device powered on, the front panel display and lights are off.	Switching power supply does not start normally.	Replace Power supply
RJ45 network cable network after the access barrier, a network connection is not on.	Transponder IP address and IP address of the computer is not connected to a network segment.	Read the instructions carefully NMS NMS transponder will change the IP address and computer IP addresses in a network without IP address.
