KIT Erbium doped fiber amplifiers
Product description
IDIL has developed a laboratory kit allowing a complete study of Erbium Doped Fiber Amplifiers (EDFA). Starting with the basic physical phenomena, this kit is suitable for the complete influence of many parameters such as the pump power, the input signal level on EDFA performances (ASE noise, saturation power, gain, etc.). The kit is complete, with different components including an optical isolator, a 1550 nm DFB laser, three attenuators, a fiber Bragg grating… The documentation explains in detail the fabrication and performance of all these components. It also contains various lecture notes and practical exercises.
- Comprehensive teaching and training manual
- Rack mounted components
- Eye safe connectors
- Competitive pricing
- Modular presentation of the kit
- Pump modulation
- Laser behaviour observation (various spectra)
Erbium Doped Fiber Amplifiers (EDFA) have revolutionized Telecommunications. They allow an amplification of 30 dB of optical signal without any bandwidth limitation, on a 40 nm band, centred at 1550 nm. Consequently, fiber optics Telecommunications systems can be upgraded only by changing the emitter and receiver systems. Their wide amplification band also enables the development of WDM transmission, with a capacity of up to 1 Tbits/s. Amplifiers are now the key elements of optical Telecommunications. This kit will allow you to understand:
- Erbium doped fiber amplifier
- Erbium doped fiber laser
- Superfluorescent source (ASE source)
- Linear cavity fiber laser
- Ring cavity fiber laser
- The constant fluorescent level start-up
- The relaxation oscillations
- Fluorescence decay
- Saturation effects
- Gain or loss dependence of the working wavelength…
