Overview Optical Fiber Amplifier From Fiberstore

Posted on by FS.COM

The Optical Amplifiers are devices that direct the amplified light signal, without the need to first convert it into an electrical signal. Prior to this, the transmission signal amplification to achieve the photoelectric conversion and electro-optical conversion, i.e., O / E / O converting. With the optical amplifier can achieve optical signal amplification. The successful development of the optical amplifier and its industrialization is a very important achievement in the optical fiber communication technology, it has greatly contributed to the development of optical multiplexing, optical soliton communication and all-optical network.

Fiber amplifier will not only directly amplifying optical signals, and also offers real-time, high gain, broadband, online, low noise, low loss optical zoom function is the key components of a new generation of optical fiber communication systems essential. The Fiber Amplifier Usually by the gain medium, the pumping light input-output coupling structure and composition. Fiber amplifier mainly erbium-doped fiber amplifier, semiconductor optical amplifiers and three optical fiber Raman amplifier according to the position and the role of the fiber amplifier in the optical fiber line relay amplification, generally divided into three pre-amplification and power amplification.

Optical Fiber Amplifier (OFA) is used in optical fiber communication lines, to achieve a new all-optical signal amplification amplifier. Erbium-doped fiber amplifier (EDFA), semiconductor optical amplifier (SOA) and optical fiber Raman amplifier (FRA), erbium-doped fiber amplifier with its superior performance in practical fiber amplifier is now widely used in long distance, high-capacity, high-speed optical fiber communication systems, access networks, optical fiber CATV networks, military systems (radar multi-channel data multiplexing, data transmission, guidance, etc.) in areas such as power amplifiers, repeaters amplifier and preamplifier.

CATV-EDFA

Coexistence of CATV network for hybrid fiber / coax structure of a variety of systems, the erbium-doped fiber amplifier is increasingly able to get attention, especially the front-end centralized system, point-to-multipoint light wave structure and long-distance trunk transmission system especially. For CATV designers most commonly tree distribution network, the efficiency of the system is determined by the cost per user. CATV amplifier is a electronic device that accept a varying input signal and produce an output signal that varies in the same way as the input, but has larger amplitude.Therefore, the use of erbium-doped fiber amplifier to increase the optical power on the basis of the original transmitting equipment, services for more users, thereby reducing the cost of the transmitter units of milliwatts. In addition, in recent years, including erbium-doped fiber amplifier 1550nm light emitting device can be the cheapest fiber to the curb and fiber to the building. All in all, CATV fiber trunk transmission and power distribution system as well as the progressive realization of the “triple play” of voice, video, data path transmission for the ultimate realization of broadband integrated services digital network, erbium-doped fiber amplifier will play an invaluable role.
