DATA

SHEET

This product is a 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.

The device is 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.

It 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 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. This

LC TOSA product is pre-aligned and focused fiber optic transmitters designed

to interface with 50/125 and 62.5/125

µm multi-mode fiber.
