Overview        TOA1000F erbium yterbium-doped fiber is used optical fiber transmission system of 1550nm wavelength working window with low noise, high gain, structural optimization and high reliability etc.The built-in microprocessor can monitor the pump working status and input/output optical power on real-time.When abnormal optical amplifier work, it will output the corresponding alarm information, when the input optical signal is too low or no input optical signals, it will automatically shutoff the pump laser to protect the optical amplifier.
       Amplifier with small in size, high reliability, easy to operate, support English interface, power supply can backup and hot plug, the output optical power is adjustable,network management using national standard management protocol, can monitor status and fault diagnosis through Ethernet directly.
       Optical fiber amplifier (OFA) is the key component to realize the optical fiber communication .Because it is easy to integration, high gain, low noise and wide bandwidth and be widely used.In recent years, as people's increasing requirement for the communication business diversification, information and communication technology obtained the rapid development. new technology puts forward higher requirements on the performance of the optical fiber amplifier.In DWDM system (Dense Waveguide Division Multiplex, DWDM), cable TV network (Community can Antenna Television be used, CATV) and optical Fiber To The Home (FTTH) high power distribution system, it requires the optical Fiber amplifier has higher saturated output power.Erbium-doped fiber is unable to provide a bigger pump absorption when through short fiber,and complex structure, the efficiency is low. So Erbium ytterbium codoping fiber is an effective method of implementation.
       FTTH has become a technical scheme and trend for two-way cable operators network construction and transformation.
       1. With the rapid development of FTTH network, FTTH network need to multiply optical node, greater amounts of optical power to cover
       2. The traditional 1310nm optical transmitter and optical fiber amplifier performance is low,and is difficult to meet those needs.
       Based on the above consideration,we propose to use 1550nm erbium ytterbium superhigh power amplification techniques for building FTTH network, on the one hand can substantially reduce the number of equipment, less investment, with the best performance/cost ratio, at the same time it can save floor space, effectively protect the precious computer resources, on the other hand, it can realize erbium yterbium-doped fiber 1+1 hot backup, full protection to key device to ensure the reliability and availability of FTTH network.
       It adopts the design of 1 u high density, simple structure, appearance with darkgrey color, mirror sticker on the front panel Features         ● 1.1 U high density design, compared with 2 U device it can save space, reduce housing construction
        ● 2.user can raise output optical power 0.5dBm, or cut 3dBm in accordance with the requirements of the link needs,more convenient and more flexible.
        ● 3.In English menu, simple easy to operate.
        ● 4.Network management port satisfy network management of international standard, it can support WEB page access,user can manege equipment remotely
        ● 5.Support dual hot backup power supply, power supply support in signal detection.
        ● 6.Useing the low power DC-DC chip, greatly reduce the power loss.
        ● 7.Temperature control fan can lower power consumption, reduce noise, and fan can be teared of installed online. Technical Specifications
