The basic configuration of an erbium-doped fiber amplifier
is shown in Figure 2.
com), a leading developer and manufacturer of Intelligent Optical Engines (IOEs), today announced that it has released the IOE 11330C and 11340C Erbium-doped Fiber Amplifiers
The SmartAmpTM integrates high power erbium-doped fiber amplifiers
, wavelength multiplexing/demultiplexing as well as power and dispersion control.
The HPU 42000 series Raman amplifiers, which feature built-in automatic gain control (AGC) function, offer ease of system implementation and excellent noise characteristics, which, in combination with erbium-doped fiber amplifiers
(EDFAs), improves optical signal to noise ratio (OSNR) as well as compensates for optical loss resulting from optical transmission lines and optical components.
Erbium-doped Fiber Amplifiers
, Principles and Applications.
Thyagarajan (Indian Institute of Technology) and Ghatak (Disah Academy) then explain the role of lasers, photodetectors, erbium-doped fiber amplifiers
, Raman fiber amplifiers, fiber Bragg gratings, couplers, isolators, external modulators, and thin-film devices in fiber optic communication systems.
According to the company, the portfolio of products distributed by AMS includes transmitters, receivers, erbium-doped fiber amplifiers
(EDFAs), transponders, transceivers and the recently released range of tunable laser-based devices.
As with al l of NP Photonics' amplifier products, the Scorpion Amplet MMP-HP7020 is based on the company's proprietary Erbium Micro Fiber (EMF) technology in which erbium-doped glass produces high optical gain over just a few centimeters of fiber, rather than over many meters, as with traditional erbium-doped fiber amplifiers
Earlier, overshadowed by erbium-doped fiber amplifiers
(EDFA), the technology is relatively immature and the markets are in their early stages.
The second innovation in this area has been the commercialization of erbium-doped fiber amplifiers
FAMILY OF ERBIUM-DOPED FIBER AMPLIFIERS (EDFA) offers a wide operating wavelength range, and is pumped with high-reliability 980 nm diode lasers.
The new optical spectrum analyzers perform spectral measurements between 600 and 1700 nm on light-emitting diodes (LEDs), Fabry-Perot lasers, distributed feedback lasers and erbium-doped fiber amplifiers
