TOS2000TOC series 1550nm auto-tracking internally modulated optical transmitter module is a module that WDM insertion system is added based on 1550nm internally modulated transmitter, which can support up to 32 IPQAM frequency points insertion. The module multiplexes the local optical signal and the main optical signal through the built-in WDM, sets the optical value difference between the local optical signal and the main optical signal according to the value of the main optical signal, and realizes the whole automatic adjustment of the insertion system through the full-automatic electric optical attenuator (VOA). The product is mainly applied to the insertion of local value-added services in the secondary service area (sub head-end), providing a high-quality and low-cost solution for the 1550nm optical fiber network system of all-optical relay system.

　　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.Excellent RF adjustment function. In order to meet the different input level requirements of users, the manual gain (MGC) function is added to change the OMI by adjusting the gain manually to ensure the device operating in the best condition.

2.It adopts original low chirp and high linearity DFB laser as signal source. 3.The perfect pre-distortion circuit ensures perfect performance of CTB and CSO in high standard CNR value.

4.Low( No) optical input, the device will turn off automatically.

5.Different networks can be optimized by OMI adjustment.

6.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.
