The HFE409x-341 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. The power monitor diode can be used with
appropriate feedback control circuitry to set a maximum power level for each
VCSEL. In addition, built-in power attenuation reduces the effective slope
efficiency. These combined features simplify design for high data rate
communication and eye safety.
The HFE409x-341 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-341 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-341 is designed to interface with 50/125 and 62.5/125 m
multimode fiber. They product circularly symmetric, non-astigmatic, narrow
divergence beams that, with appropriate lensing, fiber couple all of the emmiter
power.
