Mini Type Manual Variable Optical Attenuator (MVOA) operates by manually moving a shading element into optical beam. The shading element can be adjusted to get any attenuation value in a range. This MVOA features low insertion loss, good resolution, integrating high stability, good reliability and applies for pre-emphasis attenuation, transmitter power control, in-line power equalization and amplifier power control, etc.
The Reduced Cladding In-line Polarizer is designed to pass light with one specific polarization while blocking the other polarization.It can be used to convert unpolarized light into polarized light with high extinction ratio. It can also be used to enhance the extinction ratio of signals with its excellent polarization properties. It is ideal for high speed communication systems and test instrumentations where high polarization extinction ratio is required.
The Coarse WDM Module is expanding the bandwidth of Metro/Access Networks. The 4 channel and 8 channel CWDM modules are based on Coarse Wavelength Division Multiplexer devices. They can act as MUX/DEMUX with 20 nm channel spacing. It has low insertion loss, low PDL, high isolation and good thermal stability.
The Faraday Mirror is a passive device that provides 90 degree rotation regarding to the polarization state of the input light. The FM offers excellent performance including the lowest possible insertion loss and environmental stability. It is used in EDFAs, fiber lasers and fiber instruments to minimize the polarization effect.
The Fiber Optic Tunable Filter is based on fiber Fabry-Perot interferometer technology. Activated by a piezoelectric transducer, the device can be tuned across the entire C + L band. It is ideal for applications in signal selection, noise rejection, and spectrum analysis. Two thermistors are mounted in the filter package for temperature monitoring.
