TOS2000TBT series 1550nm internally modulated optical transmitter module 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. It is the core device for the construction of CATV transmission network, mainly used for the 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 of the 1550nm network transmission systems.

　　The product has the characteristics of small size and compact structure, and can be used with TOS2000TEL power supply and TOS2000TJK optical platform to form an optical transmission system with excellent performance.

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.The built-in microprocessor monitors all the operating status parameters of DFB laser and transmits them to the platform through the bus. The platform can monitor and display its operating status through LCD screen. The intelligent function of the platform provides a good internal operating environment for the module, so that the excellence of the module can be brought into play, with high reliability and stability.
