Low Power Optical Fiber Amplifiers

PriTel’s PMFA Series of Polarization Maintaining Optical Fiber Amplifiers are designed for R&D applications in telecommunications, fiber lasers, optical switching and microwave photonics.

Based on well-established 980-nm diode-laser Erbium-doped optical fiber technology, the FA Series of Amplifiers offers very low noise, wide bandwidth, low dispersion, and high saturation power without ASE problems. The total fiber length is shortened to enable amplification of picosecond pulses by employing a special Er-doped fiber (see PriTel's Sub Picosecond Optical Fiber Amplifiers).

PriTel's Low power amplifiers are available in both polarization insensitive (Non PM) and polarization maintaining (PM) versions.

Input/Output Power Monitors

PriTel's Optical Fiber Amplifiers are available with a Power Monitor Option. The digital display shows the power of the input and output signals. The optical monitor outputs can be used to connect to a power meter, optical spectrum analyzer, or other equipment for monitoring the signal. This reduces the need to frequently connect/disconnect the input or output, greatly reducing the probability of burning/damaging the connectors because of dirt.

Computer Control Options

PriTel's Optical Fiber Amplifiers can be configured for remote control by a computer using interfaces such as Serial/RS-232, USB, GPIB and Ethernet.
