Mini Type Manual Variable Optical Attenuator (MVOA) operates by manually moving a shading element into optical beam. The shading element can be integrated and adjusted to get any attenuation value in a range. MVOA features low insertion loss, good resolution, high stability and good reliability. The Manual Variable Optical Attenuator applies for pre-emphasis attenuation, transmitter power control, in-line power equalization, and amplifier power control, etc.
The Coarse Wavelength Division Multiplexer series is designed and manufactured based on Telcordia standard. The devices use environmentally stable thin film filter and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation and excellent environmental stability. They can be used individually to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in CWDM systems.
The Special Wavelength Coupler offers very low insertion loss, low polarization dependent loss and excellent environmental stability. Accurate coupling ratios from 0.01/99.99 to 50/50 are available with very good uniformity in the operating wavelength range. These components find extensive applications to perform power splitting and monitoring functions in all kinds of optical communication systems.
The Bandpass Filter is a micro optics device based on environmentally stable thin film filter technology. It is used to block out unwanted noise signals in EDFAs and fiber laser systems. This component is characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
The Gain Flattening Filter is a micro optics device based on environmentally stable thin-film filter technology. It is used to flatten the spectral gain in EDFAs. The components are characterized with low error function, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
