desktop type er doped optical fiber amplifier description: erfa11000 series a re desktop type er dop ed optical fiber amplifiers (edfas) for experimental use. erfa11000 series can be operat ed with commercial ac power. various models are lined up according to the output power level, gain and noise figure. features: both of edfas pumped by 1480nm lase r diodes and 980nm laser diodes are available. following three operati ng modes are available (1) acc : automatic pump lase r current control pump laser current is controll ed to stabilize pump laser power. (2) apc : automatic pump power control pump power is monitored and cont rolled using photo diode in pump laser. (3) alc : automatic amplified output power control output power level of the amplif ier is monitored and controlled. pump laser current, pump la ser power, temperature of pump laser, input power output power and returned power from output terminal are monitored. (input power monitor and returned powe r monitor are optional for erfa11031b) pump laser current, pump la ser power, temperature of pump laser and output power are displayed on front panel. maximum output power level is over +24db. (erfa11023) maximum gain is over 45db. (erfa11023) noise figure is less than 5.5db. (erfa11031b and erfa11032 pumped by 980nm laser diode(s).) erfa11000 series ft1i-03016 appearance of erfa11022
