The MN4765B is a characterized, unamplified high-speed photodiode module. It is used as an optical receiver with the Anritsu MS4640B Series VectorStar VNAs to perform highly accurate and stable optoelectronic measurements of both modulators (E/O) and photoreceivers (O/E). The MN4765B is the base calibration module part number only. Customers are required to also order an option to configure the bandwidth and wavelength coverage.
The MN4765B with option 70 configures the calibration module for 70 kHz to 70 GHz frequency and 1550 nm wavelength coverage. This option consists of a high-speed photodiode that converts modulated optical signals to electrical signals and includes additional circuitry for temperature and bias stability. The high-speed photodiode has exceptional bandwidth response to 70 GHz and a typical responsivity of 0.7 A/W. Option 71 is configured from 70 kHz to 70 GHz and 1310 nm, while Option 72 is configured from 70 kHz to 70 GHz at both 1310 and 1550 nm.
Option 110 configures the module for 70 kHz to 110 GHz and 1550 nm. Option 111 configures the module for 70 kHz to 110 GHz and 1310 nm, while Option 112 configures the module from 70 kHz to 110 GHz at both 1310 and 1550 nm.
The MN4765B with Option 140 configures the module for 70 kHz to 145 GHz and 1550 nm.The MN4765B is the first O/E module with traceability to a recognized National Metrology Institute up to 145 GHz and all O/E modules are characterized in both magnitude and phase using a NIST derived calibration standard up to 110 GHz.
Note: MN4765B is the base calibration module part number only. Customers are required to also order an option to configure the bandwidth and wavelength coverage. These options consist of a high-speed photodiode that converts modulated optical signals to electrical signals, and includes additional circuitry for temperature and bias stability.
