W1310F Optical fiber transmitter

I. Introduction

The W1310F series optical transmitters use DFB lasers as the light source to convert the wired television RF amplitude modulation signal (AM-VSB) into optical signals. These optical signals are then transmitted via optical fibers and converted back into RF signals by the OR860/1000M series optical receivers, which are then distributed to users. The main purposes are as follows:

1. Front-end program playback

2. Program exchange between front ends

3. Transmission of video and audio signals in hybrid fiber coaxial HFC (Hybrid Fiber Coaxial) network systems To ensure that this system can operate at its best efficiency and gain the trust of users, the characteristics, functions, and operation procedures are detailed in each chapter. We hope to meet the requirements of users and provide a high-quality service.

II. Performance Features

1. 19" 1U standard chassis, with LCD display on the front panel;

2. Downlink bandwidth of 45 - 870 MHz / 1000 MHz, multiple optical output power (2 - 24 mW);

3. Low RF input;

4. Pre-distortion correction circuit;

5. Automatic gain control (AGC) circuit;

6. Automatic power control (APC) and automatic temperature control (ATC) circuits;

7. RS232 interface for communication with the upper computer to achieve real-time upload of optical transmitter working status parameters and upper computer adjustment of electrical parameters for network management functions; equipped with upper computer network management software.

Internal temperature control setting, no need for fan cooling, to improve the reliability and stability of the entire machine.
