1.25GBPS 850NM VCSEL  
TO-46 PACKAGE  
DATA  
SHEET  
HFE408X-321  
The HFE408x-321 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.  
FEATURES:  
Designed for drive currents  
between 5 and 15 mA  
Optimized for low dependence  
of electrical properties over  
temperature  
High speed 1 GHz  
The HFE408x-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.  
Two different laser/  
photodiode polarities  
Attenuating coating  
The HFE408x-321 is designed to be used with inexpensive silicon or gallium  
arsenide detectors (see HFD3081-103, HFD3081-108), but excellent perfor-  
mance can also be achieved with some indium gallium arsenide detectors.  
Packaged with a photodetector  
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 HFE408x-321 is designed to interface with 50/125 and 62.5/125 µm multi-  
mode fiber. They product circularly symmetric, non-astigmatic, narrow divergence  
beams that, with appropriate lensing, fiber couple all of the emitter power.
