Product Specification
2.5Gbps 850nm VCSEL, LC TOSA
HFE4190-441, HFE4191-441
PRODUCT FEATURES
• 850nm multi-mode oxide isolated VCSEL
• Extended Temperature Range Operation (– 40 to +85 deg
operating range)
• Capable of modulation operation from DC to 2.5Gbps
• TO-46 tilt window metal can component, prealigned into
LC Sleeve
• Designed for drive currents between 3-15mA average
• Packaged with a back monitor
• Attenuated window can
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 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).
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 m
multi-mode fiber
