OLT1000D series is a high-index, multi-functional 1550nm internally modulated optical transmitter in top level. It adopts high linear DFB laser, with built-in pre-distortion compensation and AGC, APC, ATC control, which greatly improves the comprehensive index of the system.

　　OLT1000D 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 signal, digital TV signal, telephone signal and data (or compressed data) signal. It is a high-quality but low-cost solution to realize triple play and FTTx network transmission systems.

1.It adopts original low chirp and high linearity DFB laser as signal source.

2.The perfect pre-distortion circuit ensures 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 starts to work when case temperature reaches 30 ℃.

6.Built-in dual standby power supply,  hot plug in/out and automatic switching supported.

7.The operating parameters of the whole machine are controlled by  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 operating 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.
