16-Port 1550NM Optical Fiber Amplifier Wavelength Division Multiplexing for CATV Cable TV FTTH (without Network Management)

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.
- 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.
