Dual Power Suplly for 32 Port Wdm EDFA with Pon

1.Production Description
1.1 Introduction
FWAP-1550H series EYDFA optical amplifier combiner is the latest equipment of optical transmitting system for PON+CATV FTTH/FTTP. It realizes the combination function of OLT PON and CATV 1550nm after the optical signal is amplified. In detail, there is one way CATV input plus 16/32/64 routes PON signal in and the 16/32/64 routes which have 1490+1310+1550nm combined output 1550nm with 30 to 45dBm total power. This equipment is well compatible with the OLT/ONU of HUAWEI, ZTE, FiberHome, etc, and no data lost which owns high-cost performance.
Ordinary erbium-doped fiber amplifier (EDFA) has advantages of low noise, high gain, wider bandwidth, high 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 coupling into 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 milliwatt of output power and it is limited by the area of pump which makes high power pump optic cannot be coupling. It consequently causes serious output power of the optical laser. In case, it develops double-cladding fiber internationally and solves the problem of listed weakness of single packed fiber which improves 1 to 2 level for output power. It then drives the development of high power optical amplifier. After several years' research, our company overcome multiple technical difficulties, high power ytterbium-erbium co-doped double-cladding fiber amplifier was developed for CATV system to fit the requirement of FTTH and FTTB after conquer many technical difficulty.
This serious product adopts JDSU, LUMENTUM, etc multimode high power pump laser as pump source and American OFS closed beam splitter as double-cladding synthesizer. Built-in stable optical power circuit and laser thermoelectricity freezer guarantees best performance and long life cycle operating. Microprocessor software monitors operating status of laser which shows on LCD. Once operating parameter of laser deviate from the range of set value, microprocessor will cut power supply of laser automatically and red light turn will turn on with alarm (prompting fault cause on LCD).Please refer to the following "Operation Instruction" for detailed report of equipment parameters.

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 system get superior CNR through power optimize balancing techniques.
1.2.2 Reliability: adoption of 19″2U standard case, built-in high performance external modular switching power supply, operating under AC90 to 255V, 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: Microprocessor monitors operating status of pump laser which is the most valuable part of the equipment, operating parameters show on LCD display.
1.2.4 Network Management: Optional type status monitoring transponder certainly satisfy national, SCTE, HMS, WEB standard, it realizes network management monitoring function.
1.2.5 Adjustable Output Power: The equipment is advanced designed which satisfies bigger range of adjustment from lower to -2dBm (special offer).
1.2.6 High Power Output: Combined output power has maximum to 30~45dBm and multiple output configuration is available for users requirement.
1.2.7 WDM Insertion: It is available to integrate FWDM module if user need which is convenient when combines GPON, 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.
1.2.9 Built in optical path selector(customized): CATV optical signal has two way as A and B optical switch input,(OPT SWTTCH):auto(prefer)or manual(force) mode,auto mode uses path A in rule and switch to B as A is not satisfied followed path priority.
