HFE408X-321

The HFE408x-321 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. The power monitor diode can be used with

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

VCSEL. In addition, built-in power attenuation reduces the effective slope

efficiency. These combined features simplify design for high data rate

communication and eye safety.

FEATURES:

Designed for drive currents

between 5 and 15 mA

Optimized for low dependence

of electrical properties over

temperature

High speed ≥1 GHz

The HFE408x-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.

Two different laser/

photodiode polarities

Attenuating coating

The HFE408x-321 is designed to be used with inexpensive silicon or gallium

arsenide detectors (see HFD3081-103, HFD3081-108), but excellent perfor-

mance can also be achieved with some indium gallium arsenide detectors.

Packaged with a photodetector

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 HFE408x-321 is designed to interface with 50/125 and 62.5/125 µm multi-

mode fiber. They product circularly symmetric, non-astigmatic, narrow divergence

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