Using Safety Precautions

Before installing and using this product, please read the following carefully. The Company does not assume any responsibility for any loss due to security breaches caused.
Lasers and erbium-doped fiber amplifier output power laser radiation is not visible, can not look directly at the device connector end when it works to avoid burning eyes and skin.
Equipment includes precision optics, in order to avoid damage to the severe impact of its constitution, please avoid excessive vibration and impact. Pigtail easily sacrificed, so be careful.
Equipment containing electrostatic sensitive devices, handle it carefully and make sure the ground is good, the power supply is normal.
Attention of optic fiber end face:

1. Before using, please be sure to keep the input and output end face of the optic fiber clean, especially if the output end face is dirt, then it is easy to make the output end face burned and the output power will be decreasing. When cleaning the optical fiber end face or insert patch cords, please turn off the input light first.
2. The correct order of plugging optical port is:
   Inserting: first insert optical patch cord of output port, then insert optical patch cord of input port.
   Pulling out: first pull optical patch cord of input port, then pull optical patch cord of output port.
3. This kind amplifier is a high precision and high stability product, in order to have high stability output power, please use optical patch cord with good quality and which connectors are match with the device to connect with the output port. In principle, the optical patch cord should be as short as possible, and do not let it voluntary movement.

If there are any questions, please contact our company. Do not disassemble the module, otherwise it will cause irreparable damage

Description
The product is high output power C-Band Er-Yb co-doped double cladding optical fiber amplifier.
The key components of the product are high reliability multimode PUMP laser and the double cladding optical fiber. A proprietary ATC (Automatic Temperature Control) and APC (Automatic Power Control) circuit insures the high stability and reliability output power, the unique optical circuit design ensures the excellent optical performance. The high stability and high precision MPU system to ensure the control, adjustment and display are intelligent and easy.
This amplifier employ double cladding Erbium Ytterbium co-doped fiber, and employ the high power multimode pump, with a 10 times Conversion efficiency higher than the single mode general technology, and therefore have a lower relative cost and more compact size and lower power consumption, in particular, for FTTH or FTTB or other large distribution system applications.
Employ intelligent temperature control system: (1)Adopt special temperature control circuit，heat radiating and power consumption can be reduced 30%, (2)The professional air flow design can also ensure the best temperature stability, at the same time powerful fan will start when the case temperature is over 45 , meanwhile it will stop as the temperature is under 40 .The technology makes sure the thermal stability of system and fan’s long life. Intelligent network management system. Perfectly network interface: Ethernet network，and the open network management interface ensure the connectivity with all other network management system.
These products are widely used in CATV transmission system and the high power distributing system FTTH requirement. It can be used for CATV analog/digital signal distribution, or match with PON system to construction the triple network integration. (Triple wavelength WDM is optional)
