850nm, TO-46 Lensed window component, with back monitor, attenuated for eye safety (HFE4085-521)
The HFE4085-521 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. 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 HFE4085-521 is designed to interface with 50/125 and 62.5/125 µm multimode fiber. It produces circularly symmetric, nonastigmatic, narrow divergence beams that, with appropriate lensing, fiber couple all of the emitter power.
