Polarization Maintaining Optical Fiber Amplifiers

PMFA Model with

PMFA Model without
power monitor option

PriTel’s FA Series of Low Power Optical Fiber Amplifiers are designed for R&D applications in CATV, telecommunications, fiber lasers, and optical switching.

Based on well-established 980-nm diode-laser Erbium-doped optical fiber technology, the PMFA Series provides lower noise and reduced amplified spontaneous emission (ASE) than non-PM amplifiers while maintaining the input polarization with a high extinction ratio, >22 dB.

PriTel also manufactures amplifiers with excellent short-pulse performance. Certified short pulse performance is available for PriTel SPFA High Power Optical Fiber Amplifiers for pulse widths upto 300 fs (see PriTel's Sub Picosecond Optical Fiber Amplifiers).

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.
