Polarization-maintaining fibers work by intentionally introducing a systematic linear in the fiber, so that there are two well defined polarization modes which propagate along the fiber with very distinct phase velocities. The beat length Lb of such a fiber (for a particular wavelength) is the distance (typically a few millimeters) over which the wave in one mode will experience an additional delay of one wavelength compared to the other polarization mode.

The multimode component library of OptiSystem allows for simulation of links with multimode signals. OptiSystem is an optical communication system simulation package for designing, testing, and optimizing virtually any type of optical link in the physical layer of a broad spectrum of optical networks, from analog video broadcasting systems to intercontinental backbones. Created to address the needs of research scientists, photonic engineers, professors and students; OptiSystem satisfies the demand of users who are searching for a powerful yet easy to use photonics system design tool. It allows for the propagation of very short pulses, which translates to high bit rates, extremely long distances while experiencing.

Fiber optic power meters measure the average optical power out of an optical fiber. Power meters typically consist of a solid state detector (silicon for short wavelength systems, germanium or InGaAs for long wavelength systems), signal conditioning circuitry and a digital display. Optical power, required for measuring source power, receiver power and, when used with a test source, loss or attenuation, is the most important parameter and is required for almost every fiber optic test. Optical power meters for fiber optic networks: For the installation, maintenance, and testing of single-mode and multi-mode networks and cables.
