HFE4093-332
The HFE409x-332 is a high-performance 850 nm VCSEL (Vertical Cavity Surface-
Emitting Laser) packaged for high-speed data communications. This product
combines all the performance advantages of the VCSEL with a custom
designed power monitor diode, and is designed for ease of use by the module
designer and manufacturer. The power monitor diode can be used with
appropriate feedback control circuitry to set a maximum power level for each
VCSEL, simplifying design for high data rate communication and eye safety.
The HFE409x-332 is a high radiance VCSEL designed to convert electrical
current into optical power that can be used in fiber optic communications and
other applications. As the current varies above threshold, the light intensity
increases proportionally.
The HFE409x-332 is designed to be used with inexpensive silicon or gallium
arsenide detectors, but excellent performance can also be achieved with some
indium gallium arsenide detectors.
The low drive current requirement makes direct drive from PECL (Positive
Emitter Coupled Logic) or EML (Emitter Coupled Logic) gates possible and
eases driver design.
The HFE409x-332 is designed to interface with single mode or 50/125 and
62.5/125 µm multimode fiber. HFE409x-332 produces a circularly symmetric,
non-astigmatic, narrow divergence beams that, with appropriate lensing, fiber
couple all of the emitter power.
