ETC HFE4090-321

Fiber Optic LAN Components
High Speed VCSEL 2.5Gbps
HFE4090-321
FEATURES
• Designed for drive currents
between 5 and 15 mA
• Optimized for low dependence
of electrical properties over
temperature
• High speed ≥1 GHz
The HFE4090-321 is a high-performance 850 nm VCSEL (Vertical Cavity
Surface-Emitting Laser) packaged for high-speed data communications.
LASER RADIATION
AVOID EXPOSURE TO BEAM
CLASS 3B LASER PRODUCT
The HFE4090-321 is a high radiance VCSEL 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.
The HFE4090-321 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 HFE4090-321 is designed to interface with 50/125 and 62.5/125 µm
multimode fiber. It produces circularly symmetric, non-astigmatic, narrow
divergence beams that, with appropriate lensing, fiber couple all of the emitter
power.

Notes:
1. Operating power is set by the peak operating current IPEAK=IBIAS+IMODULATION.
2. Operation at temperatures outside the specified range may result in the threshold current exceeding the
maximums defined in the electro-optical characteristics table.
3. Slope efficiency is defined as ∆Po/∆IF.
4. Rise and fall times are sensitive to drive electronics.
Beam divergence is defined as the total included angle between the 1/e2 intensity points.

Threshold Current vs. Temperature: Threshold
current varies parabolically with temperature; thus it can
be nearly constant for a limited temperature range.

NOTICE
The inherent design of this component causes it to be
sensitive to electrostatic discharge (ESD). To prevent ESDinduced damage and/or degradation to equipment, take
normal ESD precautions when handling this product.

The VCSEL is a class IIIb laser and should be treated as a
potential eye hazard. Due to the size of the component, the
applicable warning logotype, aperture label, and certification/
identification label cannot be placed on the component itself.
These labels can be found on the individual envelope in
which the VCSEL unit is packaged, or attached to the
shipping package.
