Specifications

Description
1. SNP7500 (I), SNP8600 (I) Series 1310nm CATV Laser Transmitter is an important equipment to build CATV HFC network. It is mainly used for long-distance optical fiber transmission of television image signal, digital TV signal, telephone voice signal and data (or compressed data) signal.
2. The High-performance DFB lasers, we select famous brand from the international market for our products as light source. RF power digital automatic processing technology developed and operated by ourselves and RF pre-distortion circuit are used in the part of RF drive. Microcomputer automatic control system is built in it to ensure excellent performance machine.
3. Since 1997, we successfully developed the first 1310nmCATV laser transmitter, there are continue Innovation of product technology and improvement of line structure and quality indicators. We launched SNP Series 1310nmCATV laser transmitter currently. Its line technology is in the leading position in China, and its process quality is as good as imports. We have developed wide machine to solve the problem that indoor room can not be built in some remote areas based on engineering practice needed by customers.

 
 
Feature
1. The High-performance DFB lasers with narrow lines, good linear and high output power (the highest output power up to 30mw),we select famous brand from the  international market for our products.
2. RF power digital automatic processing technology developed and operated by ourselves is used in the part of RF drive. It automatically adjusts the RF drive power according to the input RF signal level and channel number (15 ~ 84Channels) to ensure CSO, CTB and C / N index in the best value and overall system performance.
3. Advanced multi-frequency RF pre-distortion technology with the latest full RF GaAs Device improve the CTB and CSO target the major target of CATV system and the C / N index  get the maximum  promotion.
4. Built-in perfect microcomputer automatic control circuit, monitor a variety of working conditions of output power and laser in real time, to make sure the optical output power is steady and extend the working life of the laser.
5. Blue VFD Display displaying the operating parameters and fault information are built in 19” 1U High-standard Rack.
6. There are IEEE802.3 10Base-T standard Ethernet network interface and RS-232 Interface supporting (Specification of equipment management system for HFC network), So that the network management monitoring can be easily achieved.

Special Notice:
The performance parameters of this manual according to GY/T 143-2000 <Specifications and methods of measurement on AM optical transmitter and receiver used in CATV system> .We get it under the following testing environment.
 
Testing Environment:
Together with Standard 1550nm External Modulation Optical Transmitter, 10km standard optical fiber and optical passive attenuator make the testing circuit .Set with 59 PAL-D analog TV channel signal at range of 550MHZ in the fix index loss of circuit, transmit digital TV signal at rang of 550MHZ~862MHZ, the electricity (8 MHZ bandwidth) digital signal is 10dB lower than analog signal of carrier electricity level. When the input of optical receiver is -1dBm, measure C/CTB, C/CSO, C/N. 

Ordering Guide
1. Please check the optical interface of the equipment when ordering. The defaulted interface is FC/APC interface. If you have other special requirements, please tell us when ordering.
2. When customer some special requirement on key components such as lasers please tell us when ordering.
