Product Description


FWA-1550H series EYDFA optical amplifier

Product Description

FWA-1550H series EYDFA optical amplifier is the latest equipment of optical transmitting system for CATV FTTH/FTTP. In detail, there is one way CATV inputoutput 1550nm with 30 to 40dBm total power.
Ordinary erbium-doped fiber amplifier (EDFA) has the advantages of low noise, high gain, wider bandwidth, highly efficient pumping, and stable operating, which is widely used in CATV systems. However, along with the implementation of fiber to the house (FTTH), system C/N will be worse significantly when EDFA uses as cascade amplification. Therefore, EDFA is required to produce high saturation output power and low distortion as shown as 13dBm to 23dBm (approximate. 27dBm limited) for EDFA saturated output power. Moreover, the gain fiber of EDFA is single-mode and single-packed fiber. The optic of the pump is directly coupled to the fiber but the diameter of the fiber is very small therefore it requires a single mode of pump optic. The semiconductor of single mode only supports hundreds of milliwatts of output power and it is limited by the area of the pump which makes high-power pump optic cannot coupling. It consequently causes serious output power of the optical laser. In case, it develops double-cladding fiber internationally and solves the problem of the listed weakness of single-packed fiber which improves 1 to 2 levels for output power. It then drives the development of high-power optical amplifiers. After three years of research, high-power ytterbium-erbium co-doped double-cladding fiber amplifier was developed to fit the requirement of FTTH and FTTB after conquering many technical difficulties.
This series product adopts LUMENTUM, IPG, etc multimode high power pump laser as the pump source, and American OFS closed beam splitter as the double-cladding synthesizer. Built-in stable optical power circuit and laser thermoelectricity freezer guarantee the best performance and long life cycle operating. Microprocessor software monitors the operating status of the laser which shows on the LCD. Once the operating parameter of the laser deviates from the range of the set value, the microprocessor will cut the power supply of the laser automatically and the red light turn will turn on with an alarm (prompting a fault caused on LCD).

1.2 Features
1.2.1 High Quality: Adoption of multimode high power pump laser and power is optimized by software which maximizes lower NF of EDFA rival to normal EDFA. It makes the system get superior CNR through power optimize balancing technique.
1.2.2 Reliability: adoption of 19″2U standard case, built-in high-performance external modular switching power supply, operating under AC90 to 265V, optional DC48V power supply (pre-order) hot-plugging supported, automatic temperature control case heat dissipation with dual power cold&hot backup.
1.2.3 Intuitive: The microprocessor monitors the operating status of the pump laser which is the most valuable part of the equipment, operating parameters show on the LCD display.
1.2.4 Network Management: Optional type status monitoring transponder certainly satisfy national, SCTE, HMS, and WEB standard, it realizes network management monitoring function.
1.2.5 Adjustable Output Power: The equipment is advanced designed which satisfies a bigger range of adjustment from lower to -2dBm (special offer).
1.2.6 High Power Output: Combined output power has a maximum of 30~45dBm and multiple output configuration is available for users' requirement.
1.2.7 WDM Insertion: It is available to integrate the FWDM module if the user needs which is convenient when combining GPON, and EPON.
1.2.8 Connecting Safety Mode: To prevent the optical patch cord end face from being burnt when the optical output is connected, enable this mode to reduce the output power direct to 19dBm during connection. Once turn off this mode, it returns to the original set power.
