DESCRIPTION
FLD3C5KM/LK-B is an InGaAsP/lnP double heterostructure laser
diode module in a small coaxial type package for single mode fiber
including an InGaAs PIN monitor photodiode, designed for use in
data links and local area networks in the 1.3µm wavelength region.
The laser diode which uses a specially designed structure, called
MQW (Multi Quantum Well), to ensure low operating current and stable
CW operation over a wide temperature range. This assures long life and high
reliability.
The module can operate from -40 to +85°C. The monitor photodiode which receives
emission power from the rear facet of the laser diode, can be used to control the optical power
coupled into the fiber. YAG laser-welding is used in the package assembly for high package stability.
