The L-com PPMDI-P31-191 is a PM (Polarization Maintaining) dual stage passive isolator from ShowMeCables that guides light at 1310nm while minimizing back reflection and back scattering in the reverse direction for any state of polarization. The fiber optic isolator is designed for operation at a 1310nm wavelength, which preferentially transmits light in the forward direction. This optical isolator is manufactured using PANDA fiber which allows it to maintain a high polarization extinction ratio (PER). The leads are 900um diameter and 1 meter length specialized fiber built into each side of the isolator.
The PPMDI-P31-191 passive isolator is a polarized maintaining dual stage isolator offered in Grade P (Premium) used to mitigate polarization instability and offers higher performance for dispersion, cleaner signal, low insertion loss, and minimize dispersion penalty. It features a package size of 5.5 x 35mm and narrow key FC/APC connectors. Our 1310nm passive isolator has an operating temperature range from -5 to 70°C, which adds temperature stability.
This L-com PPMDI-P31-191 PM dual stage passive isolator from ShowMeCables is in stock and ready to ship same-day. This dual stage isolator, Grade P (Premium) has a high PER (Polarization Extinction Ratio), compact “In line” package, high stability and reliability, and greater isolation ideal for applications in fiber amplifier systems, pump laser diodes and optical fiber sensors.
