The PERM-800 optical power meter is an innovative solution to directly measure the output polarization extinction ratio from a fiber. It features unmatched low cost, large dynamic range, and high resolution. The design accepts all types of fiber connectors as well as free space laser beam. One attractive option is bare fiber can be conveniently insert into the meter, which matches our PM fusion splicer fiber holder. The PERM-800 is also an optical power meter.
The design adds a manual rotary polarizer to an optical power meter. As the polarizer rotates about 90 degree, maximum and minimum intensity readings are obtained and the ratio is ER. The rotation is continuous, providing high resolution and accuracy. For connector test, the polarizer rotary is pre-aligned to the key. The ease of operation has been proven in production and laboratory environments. The PERM-800 is ideal for PM fiber pigtailing of laser diodes, PM fiber patch cord manufacturing, PM fiber connectorization, PM fiber fusion splicing, PM fiber coil production and quality assurance for fiber gyros.
