Open circuit voltage /  Напруга холостого ходу       
A photovoltaic voltage developed in a photodiode when the load resistance is infinite. This open circuit voltage depends on the light level but is nearly constant at fairly low and higher light levels.

Open-loop gain /  Коефіцієнт підсилення без зворотного зв’язку       
This is the gain of an operational amplifier with no feedback applied, and represents the ratio of the output voltage to the input voltage. Units are in dB.

Optical return loss (ORL) /  Оптичні втрати на віддзеркалення       
The ratio of the reflected return light to the incident light. If the reflected return light level is high, the laser diode oscillation on the transmit side will become unstable causing relative intensity noise to increase. The reflected return light level must therefore be minimized. As solutions for this problem in receptacle type modules, an optical isolator, or a ferrule called a “stub” (component with the fiber insertion side polished for physical contact and the device side polished slantwise) is often inserted in the optical path to minimize the optical return loss.
