These products are high-performance 850nm VCSELs (Vertical Cavity Surface-Emitting Lasers) designed for high-speed data
communications and packaged 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 the VCSEL. These combined features simplify design for high data rate
communication and eye safety.
These products are high radiance VCSELs 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.
These products are 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 HFD3180-002 and HFD3180-102 product data sheets).
The low drive current requirement makes direct drive from PECL (Positive Emitter Coupled Logic) or ECL (Emitter Coupled Logic)
gates possible and eases driver design.
VCSELs produce circularly symmetric, non-astigmatic, narrow divergence beams that, with appropriate lensing, fiber couple all of the
emitter power. These LC TOSA products are pre-aligned and focused fiber optic transmitters designed to interface with 50/125 and
62.5/125µm multi-mode fiber
