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 mm
multimode fiber. HFE409x-332 produces a circularly symmetric, non-astigmatic, narrow
divergence beams that, with appropriate lensing, fiber couple all of the emitter power.
