The HFE4085-321 is a high-performance 850 nm VCSEL (Vertical Cavity Surface-
Emitting Laser) packaged for high-speed data communications.
The HFE4085-321 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 HFE4085-321 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 HFE4085-321 is designed to interface with 50/125 and 62.5/125µm
multimode fiber. It produces circularly symmetric, non-astigmatic, narrow
divergence beams that, with appropriate lensing, fiber couple all of the
|emitter power.
