MN4765B

O/E Calibration Module

The MN4765B is a characterized, unamplified 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).

Fast and accurate optoelectronic measurements- The MS4640B VectorStar series VNAs, when calibrated using the MN4765B module, enable error-corrected Transfer Function, Group Delay, and Return Loss measurements of E/O and O/E components and subsystems
National Institute of Standards and Technology derived characterization - Magnitude and phase characterization is obtained using a primary standard characterized by NIST and held in the Anritsu Calibration Lab. The magnitude and phase data is provided on a USB drive with the module
Temperature Stable - The MN4765B is thermally stabilized to eliminate drift in photodiode performance over temperature
Internal Biasing - Accurate bias voltage to the photodiode is maintained internally. An external, multi-country, AC adapter is included for easy operation
High Linearity - Linear operating range to +6 dBm for transfer function measurement uncertainties of <0.45 dB @ 50 GHz and <0.7 dB @ 70 GHz (typical specifications for MN4765B-0070)
High Responsivity - 0.7 A/W and 0.5 A/W (Typical specification for MN4765B-0070 and -0110 respectively)

Operating Frequency Range: 70 kHz — 110 GHz
Operating Wavelength Range: 1480 nm — 1620 nm
Phase Uncertainty (OE output level > -40 dBm): ± 3.0° @ 50 GHz, ± 4.1° @ 70 GHz, ± 6.5° @ 110 GHz
Frequency Response Uncertainty (OE output level > -40 dBm): ± 0.35 dB @ 50 GHz, ± 0.48 dB @ 70 GHz, ± 0.70 dB @ 110 GHz
Magnitude Response Repeatability (OE output level > -40 dBm): ± 0.15 dB @ 50 GHz, ± 0.20 dB @ 70 GHz, ± 0.30 dB @ 110 GHz
