OLT6000D series 1550nm auto-tracking internally modulated optical transmitter is a device that WDM insertion system is added based on 1550nm internally modulated transmitter, which can support up to 32 IPQAM frequency points insertion. The device 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.

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 can be worked as two types of device. It can be used as normal internally modulated optical transmitter through front panel operation,  SNMP or WEB manager.

3.It adopts original low chirp and high linearity DFB laser as signal source. 4.The perfect pre-distortion circuit ensures perfect performance of CTB and CSO in high standard CNR value.

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

6.Different networks can be optimized by OMI adjustment.

7.Fully automatic case temperature control, intelligent fans, the fans starts to work when case temperature reaches 30 ℃.

8. Built -in dual standby power supply,  hot plug and automatic switching supported.

9. 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.

10.Standard RJ45 interface provided, supporting remote network management of SNMP and WEB.
