Product Description

Brief Descriptions

This transmitter is a high-index, multi-functional 1550nm internally modulated optical transmitter at the top level. It adopts a high linear DFB laser, with built-in pre-distortion compensation and AGC, APC, and ATC control, which greatly improves the comprehensive index of the system.

ST1550I series 1550nm internally modulated optical transmitter is the core device for the construction of CATV secondary transmission networks. It is mainly used for value-added services such as TV image signals, digital TV signals, telephone signals, and data (or compressed data) signals. It is a high-quality but low-cost solution to realize triple play and FTTx network transmission systems.
Functional Features

1. It adopts the original low chirp and high linearity DFB laser as a signal source.
2. The perfect pre-distortion circuit ensures the perfect performance of CTB and CSO in high standard CNR value.
3. Automatic gain (AGC) control enables stable output in different RF input levels.
4. Different networks can be optimized by OMI adjustment.
5. Fully automatic case temperature control, intelligent fans, the fans start to work when the case temperature reaches 30 ℃.
6. Built-in dual backup power supply, hot plug, and automatic switch supported.
7. The working parameters of the whole machine are controlled by the microprocessor and the LCD status display on the front panel has many functions such as laser status monitoring, parameter display, fault alarm, network management, etc.; once the working parameters of the laser deviate from the allowed range set by the software, the system will alarm promptly.
8. Standard RJ45 interface provided, supporting remote network management of SNMP and WEB.
