The EDFA optical amplifier units can be used in telecom and datacom (SONET/SDH/DWDM/Gigabit Ethernet) applications to change an electrical signal into an optical signal and vice versa.
This SMF fiber length is determined by the required optical signal power at the input of the optical amplifier, which is very important due to amplifier saturation effect, especially when using a SOA.
To address these constraints, especially in upstream bursts(2), Fujitsu and Fujitsu Laboratories have developed a burst-mode optical amplifier technology with a semiconductor optical amplifier (SOA)(3), an integrated SOA-array(4) module fabrication technology, and an SOA chip fabrication technology enabling uncooled operation.
The linear optical amplifier, a semiconductor device with a tiny built-in laser, can simultaneously amplify dozens of different-wavelength broad-casts without distortion.
For the other applications, in-line amplification or preamplification, the design of the optical amplifier can be optimized according to the required specifications.
