LC TOSA PACKAGE
HFE419X-441
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 HFD3180-103 and HFD3180-108
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 62.5/125 µm multi-mode fiber.
