1550NM 32-Port 22DB + WDM Optical Fiber Amplifier EDFA Fiber Optic Amplifier FTTH Accessory

1550NM 32-Port 22DB + WDM Optical Fiber Amplifier EDFA Fiber Optic Amplifier FTTH Accessory

Description:
This product is a high stability output HPEDFA. The core device adopts high-reliability Pump laser, and adopts unique APC (automatic power control) and ATC (automatic temperature control) circuits, which make the output power stable and reliable; the unique optical path ensures excellent optical path indicators; high-stability and high-precision MPU (microprocessor) system is easy to adjust, display; reliable and intelligent to use.

HPEDFA boasts low noise, high gain, large bandwidth, high pumping efficiency and stable performance, widely used in CATV systems. Due to the sharp increase of CATV network users, excessive use of EDFA will increase power dissipation power and excessive series connection will cause system C/N degradation. In recent years, a new type of double-clad optical fiber has been developed internationally. The use of cladding pumping technology overcomes the above-mentioned shortcomings of single-clad fibers, increases the output power by 1 to 2 orders of magnitude, and greatly promotes the development of high-power fiber amplifiers.

Features:
- High quality: The pre-pump adopts 980nm as small signal amplification, and a dedicated pulse width constant temperature cooling chip. The rear stage adopts imported high-power multi-mode pump, the power is precisely controlled by hardware circuit APC, AGC, and dual-pump hot backup design, which minimizes the NF of HP EDFA, which is comparable to conventional EDFA. The system can obtain excellent CNR.
- Flexibility: Adjustable range of output optical power (-3 to -6dB), users need to specify when ordering. Multi-port low power, reasonable distribution of output power. The demultiplexer required for 1310/1490/1550nm EPON and GPON can also be integrated inside, which greatly facilitates network applications with EPON.
- Intuitiveness: The built-in microprocessor of the machine monitors the working state of the pump laser. At the same time, the panel LCD can display the working parameters.
- Network management type: The optional status monitoring transponder is compatible with the SCTE HMS standard, which can realize network management monitoring.
- Power plug-in type: The plug-in type switching power supply adopts aluminum profile structure, which is conducive to heat dissipation and replacement. And dual power hot and cold backup.
- With EMC, LVD, and CE certification.
- Intelligent pump over-temperature protection. When the pump temperature exceeds 50℃, the pump is automatically turned off. When the temperature is lower than 50℃, the pump will automatically start to work.

Precautions:
- Please read the following carefully before installing and using. We are not responsible for any loss caused by breach of safety matters.
- The output of the laser and erb-mirror co-doped fiber amplifier is high-power invisible laser radiation. When the equipment is working, please not look directly at the end face of its connector to avoid burning eyes and skin.
- The device contains precision optical components, in order to avoid serious impact damage to it, please avoid severe vibration and collision. Fiber pigtails are easy to break, please handle with care.
- The device contains electrostatic sensitive devices, please handle with care, and ensure that the grounding is good and the power supply is normal.

Special Precautions for Fiber End Face:
1. Be sure to keep the end faces of the input and output pigtails clean before use. When there is dirt on the output end face, it is easy to burn the end face of the output pigtail and reduce the output power. When cleaning the fiber end face or inserting optical jumpers, please turn off the input light first.
2. The correct order of plugging and unplugging the optical port is: Plug: first insert the optical jumper of the output port and then insert the optical jumper of the port; Unplug: first unplug the optical jumper of the input port, and then unplug the optical jumper of the output port.
3. The HPEDFA is a product with high precision and high stability. In order to make the output power have high stability, please use the optical jumper with good quality and the interface matching with the device to connect the output port. In principle, the shorter the jumper, the better. Please not let the jumper move freely.
