Abstract: A multiwavelength, multistage optical amplifier, which can be arranged in a cascade, substantially increases the degree of automatic power control (APC), multiwavelength APC (MAPC), and multiwavelength automatic gain control (MAGC), for at least two wavelengths. The multiwavelength, multistage optical amplifier or amplifier cascade has at least two spectrally different gain media (GM), i.e. first and second GM, connected in series for amplifying a signal having at least two wavelengths, i.e. first and second wavelengths. The first GM may be aluminosilicate erbium doped fiber, the second GM may be germanosilicate erbium doped optical fiber. The gain at the first wavelength is smaller than the gain at the second wavelength, while the signal power at the first wavelength is larger than the signal power at the second one, and vice versa. This may automatically compensate for loss tilt. The gain media may be homogeneously broadened.

The LED module includes an LED package in which at least one LED chip is mounted, and first and second wire sockets respectively making contact with lead frames formed at two sides of the LED package. The bottom chassis has a coupling hole formed through a bottom portion for receiving a coupling hook of the LED module. Thus, a wire socket is configured to make contact with a lead frame formed at a side portion of an LED package and power is received through a wire inserted through the wire socket, so that an additional printed circuit board (PCB) or an additional flexible printed circuit board (FPCB) for providing the LED package with power may be omitted.
