Erbium doped fiber / Education systems

Amplifier and fiber training kit

Erbium doped fiber summary

The aim of this educational kit is to familiarize students with optical components for Telecommunications (Laser diodes, optical fibers, isolators…). We propose a kit containing a laser diode pump, a multiplexer and an erbium doped fiber.

With different components (attenuators, coupler, DFB laser, Bragg Gratings…), it is possible to study :

  • the erbium doped fiber amplifier
  • the superfluorescent source
  • the linear and ring laser

    Amplification

    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.

    IDIL Fibres Optiques 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.
