New 100V GBBL SLCs for Optical Modules
May 29, 2014
Extended range Receive Optical Sub-Assemblies (ROSAs) for fiber optic network systems require high sensitivity Avalanche Photo-Diode (APD) detectors instead of the standard PIN-diode detector. To improve detector sensitivity, the bias to an APD must have a high capacitance broadband filter on the power input to the device. This filter prevents high-frequency noise getting to the APD via the power input and interfering with the incoming signal. JTI SLCs using our GBBL dielectric fit the capacitance and broadband requirements for PIN-diode detector input power filtering and the VCC filtering for the associated signal processor. With the 63V and 100V ratings now available, GBBL capacitors can now also be used for the input power filtering on an APD device. Production volumes are shipping and samples are available from stock.
