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.
