Overview
FCW-1550H series1550nm Erbium ytterbium co-doped fiber amplifier has advantages of low noise, high gain, wide bandwidth, efficient pump and stable working condition, etc. It is used on CATV system widely.
As the transmitting nodes in the CATV system increase constantly, fiber to the home (FTTH) and fiber to the building (FTTB) are popular. When the EDFA is used to cascaded amplification in the CATV system, the C/N deterioration is serious, so the EDFA must have high saturated output power, low distortion, while the saturated output power of EDFA is usually between 13dBm and 23dBm, output power limit is about 27dBm. In addition, the gain fiber of EDFA is single-mode and single-clad fiber, pump is directly coupled into fiber core, while fiber core is very small, it is required the pump is single-mode. The output power of single-mode semi-conductor laser is just several hundreds mW, and it is limited by pump area, high power pump can’t be coupled, thus it has a serious effect on the output of fiber laser.
Fetures
1.High quality: adopt multimode large power pump laser, power is optimized reasonably by software, and can most unlimited reduce NF of EDFA, it is comparable with EDFA. The feature can make system achieve excellent CNR.
2. Reliability: The 19 "1U standard rack, built-in high-performance plug-in dual power supply, it can work at 85~265Vac City Network Voltage, As well as an optional DC48V power supply (reservations required); chassis cooling can be automatic control by temperature.
3. Intuition: The pump laser is the most expensive machine components, machine equipped with microprocessor monitors the working state of the laser, the panel LCD window displays the operating parameters.
4. Network type: Select All-piece status monitoring transponder guarantees to meet the national standard and be compatible with the SCTE HMS standard, it enables network management to monitor capabilities.
5.Integrated WDM, more concise in using of GPON/EPON.
