Low-Noise High Power Optical Fiber Amplifiers
PriTel's LNHPFA and LNHPFA-NMA Series of Low-Noise High Power Optical Fiber Amplifiers are designed for R&D applications in 1550 nm telecommunications, fiber lasers and optical switching.
The LNHPFA and LNHPFA-NMA Series offer the lowest noise and the highest saturation output power at input powers as low as -40 dBm. The input signal is first amplified in the pre-amplifier and then boosted in the power amplifier, both integrated into the same unit. By inserting an optical band-pass filter between the preamp and power amp, the out of band noise is greatly diminished.
In the LNHPFA Series, the pre-amplifier optical output can be accessed, allowing the user to place an optional tunable filter between the two stages to suppress ASE from the pre-amplifier. In the lower-cost LNHPFA-NMA Series, no mid-stage access to the optical output from the pre-amplifier is present.
PriTel's LNHPFA and LNHPFA-NMA series of amplifiers are available in both polarization insensitive (Non-PM) and polarization maintaining (PM) versions and also with the Input/Output Power Monitor option. Short-pulse versions of the LNHPFA and LNHPFA-NMA are available using PriTel's Sub Picosecond Optical Fiber Amplifiers). Please contact us for more information.
