Optical transmitters are typically one of the following types EXCEPT:
Overfilled launch (OFL) is not a type of optical transmitter. Optical transmitters typically include devices like light-emitting diodes (LEDs), short wavelength laser compact discs (CDs), vertical cavity surface emitting lasers (VCELs), and laser diodes (LDs). OFL refers to a method used in fiber optics to launch light into a fiber, not an actual transmitter.
