Packaged in a fiber receptacle sleeve, this high radiance VCSEL is 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. Data rates can vary from DC to above 2 Gb/s.

The HFE438x-521 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 (see HFD3381-108).

Key Features:

TO-46 tilt window metal can component, prealigned into SC Sleeve
Designed for drive currents between 5 and 15 mA
Optimized for low dependence of electrical properties over temperature
High speed ≥1 GHz
Two different laser/ photodiode polarities
Attenuating coating
Packaged with a photodetector
