    Investigation on long-reach broadcast/multicast-capable WDM-PON by Cai, Frank Laifa

    Published 2011
    “…At the Central Office (CO), two DRAs are used by employing co-propagating pumping technique to achieve high gain after propagating through a 120km feeder fiber. In addition, an EDFA was also employed just before the demultiplexer at the CO to amplify the uplink transmission signals. …”

    Gain Control in L-Band Erbium-Doped Fiber Amplifier Incorporating Broadband Fiber Bragg Grating by Harun, Sulaiman Wadi, Tamchek, Nizam, Poopalan, Prabakaran, Ahmad, Harith

    Published 2002
    “…Gain control in a two-stage long-wavelength (L-band) erbium-doped fiber amplifier (EDFA) is demonstrated. Two circulators and a broadband fiber Bragg grating (FBG) are used to route a wasted backward conventional band (C-band) amplified spontaneous emission (ASE) from the second stage and launch it back into the input end of the first stage. …”

    Design And Development Of A Broadband Erbium Doped Fiber Amplifiers by Mohemad Kassir, Aiman Mohemad

    Published 2003
    “…However, the spread and expansion of dense wavelength division multiplexing (DWDM) systems are keeping pace with various technology developments of optical amplifiers and, in particular, the bandwidth broadening of EDFAs. For this thesis, a novel EDFA structure is developed to increase the amplifier bandwidth by combining the conventional band and long wavelength band (C+L). …”

    Simulation and performance analysis of the sub carrier multiplexed radio over fiber system by Arsat, Mahyuddin

    Published 2007
    “…Whereby, the transmission link was modelled using standard single mode fiber up to 150 km communication distance with EDFA 0m – 5m length. At the receiver end, the light carrying the radio subcarrier multiplexed signal is photo-detected by a PIN photodiode.…”
