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 -30 dBm. Each model integrates a low-noise preamplifier and a power amplifier into the same unit. In the LNHPFA Series, the optical output from the preamplifier can be accessed, allowing the user to place an optional tunable filter between the two stages to suppress ASE from the preamplifier. In the lower-cost LNHPFA-NMA Series, no mid-stage access to the optical output from the pre-amplifier is present. Short-pulse versions of the LNHPFA and LNHPFA-NMA are also available using PriTel's Sub Picosecond Optical Fiber Amplifiers.
