Fiber Optic LAN Components

High Speed VCSEL 2.5Gbps

HFE409x-322

FEATURES

• Designed for drive currents

between 5 and 15 mA

• Optimized for low dependence

of electrical properties over

temperature

• High speed ≥1 GHz

• Two different laser/

photodiode polarities

• Attenuating coating also

available

The HFE409x-322 is a high-performance 850 nm VCSEL (Vertical Cavity

Surface-Emitting Laser) packaged for high-speed data communications. This

product combines all the performance advantages of the VCSEL with a custom

designed power monitor diode, and is designed for ease of use by the module

designer and manufacturer. The power monitor diode can be used with

appropriate feedback control circuitry to set a maximum power level for each

VCSEL, simplifying design for high data rate communication and eye safety.

• Packaged with a photodetector

LASER RADIATION

AVOID EXPOSURE TO BEAM

CLASS 3B LASER PRODUCT

The HFE409x-322 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 HFE409x-322 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 HFE409x-322 is designed to interface with 50/125 and 62.5/125 µm

multimode fiber. They product circularly symmetric, non-astigmatic, narrow

divergence beams that, with appropriate lensing, fiber couple all of the emitter

power.
