OLA1200 series 1550nm RF EDFA is combination of a self-tracking internally modulated optical transmitter and an EDFA. Through the built-in WDM, the optical local inserted line and the optical main line are multiplexed. The mixed signal amplified after the full-automatic electronic dimming attenuator (VOA) is used to realize the automatic adjustment of the whole insertion system according to the value difference of optical local line and optical main line. 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 device core components adopts the world's top brand laser, pump laser and erbium-doped fiber. The optimized optical design and production process ensure the best optical performance. The perfect electronic controlled modes of APC (automatic power control), ACC (automatic current control) and ATC (automatic temperature control) circuits are adopted to ensure high stability and reliability of the output power, at the same time, it also guarantees excellent optical path index.

　　MPU (microprocessor) with high stability and precision is adopted in the system. The optimized thermal structure design , good ventilation and heat dissipation design ensure the long life and high reliability of the equipment. Based on the powerful network management function of TCP / IP protocol, network monitoring and head-end management can be carried out for the status of multiple node equipment through RJ45 network management interface, supporting multiple power redundancy configurations , which improved the practicability and reliability of the device.

1.Built-in optical attenuator (VOA) can automatically adjust the local inserted optical signal according to the value of the main optical signal.

2.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 working in the best condition.

3.It adopts  low-chirp &high linearity DFB laser of famous brand as laser source.

4.It adopts the world's top brand pump laser and erbium-doped fiber

5. Perfect APC, ACC and ATC optical circuit design to ensure low noise, high output and high reliability of the device in the whole operating  band (1530 ~ 1563nm).

6.There are two operating mode for choice under the condition of no input or low input in main line:1. Automatically shut down  2. Operate as only 1550nm internally modulated optical transmitter.

7.Max output reaches 27dBm

8.Built-in dual power supply, automatically switched and hot plug in/out supported.

9.The operating parameters of the whole device 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 is provided, supporting SNMP and WEB remote network management.
