Optical Coupler Directivity Test
Directivity is defined as the ratio of the leakage of the incident signal to the fully reflected signal.

How to test the sensitivity of an optical module
Unstressed receiver sensitivity testing is performed by simply connecting the transmitter to the receiver via a variable optical attenuator. BER values are recorded against different receiver power values and are finally plotted against each other. In optical communication systems, sensitivity is a measure of how weak an input signal can get before the bit-error ratio (BER) exceeds some specified number. It specifies a module's capability to perform in harsh environments and helps network. Whether you're a network engineer validating new inventory or an integrator preparing for deployment, knowing how to test optical transceiver modules can save time, reduce failures, and ensure SLA compliance.

How to test the wavelength of an optical module
Therefore, we need to use a wavelength meter or wavelength sensor to measure the wavelength of the optical module and compare it with the specified wavelength range. Accurately testing an optical transceiver means proving two things: that the module is emitting the right power at the right wavelength, and that the link it's attached to delivers that signal without unexpected loss or reflections. An optical spectrum analyzer (OSA) quantifies and displays the power of an optical light source over a given wavelength range. Think of it as a "microscope for light," revealing details invisible to the naked eye. Digital Diagnostic Monitoring is a technology that enables real-time monitoring of various parameters in optical modules.
