Fiberpark's optical isolator is high isolation, high performance and polarization insensitive components. Isolators are designed to provide very low insertion loss, PDL and extremely low PMD over the entire temperature and wavelength ranges.
Optical isolator is used in many applications, such as laser applications where they are used to prevent unwanted feedback into the laser source. This helps in not affecting the coherence of the laser affecting any damage to the diode itself as feedback is capable of frequency shift, noise, mode hopping or amplitude fluctuation. It is thus a key device in order to achieve stable laser diode operation. In high-speed optical fiber transmittance amplifiers and routes, they are considered indispensable devices due to their capability of eliminating the adverse effect of return beams.
