[1] Plesiosynchronous, or nearly synchronous, refers to a system in which separate network nodes use nominally identical (but not synchronous) master clocks. The system handles minor drift between the clocks by occasionally inserting or removing pad bits or multibit symbols. The most familiar example was the international telecom network prior to the advent of SONET/SDH.

[1] The TIA converts photocurrent to a voltage swing, and its gain is thus measured in ohms.
[2] This type of photodetector is designed to operate at relatively high voltages and electric field strengths so that the photoinduced charge carriers are accelerated to the point that they will collide and produce additional ionization within the device. ...
