Description

The LST0605-FC-A series has
been developed for low cost,
coolerless low power single

FC style connector. Both the
buried heterostructure laser
and the monitor photodiode
are manufactured using the
Hewlett-Packard MOVPE
process.

Laser Safety Warning

This device is a Class IIIb (3b) Laser Product. It may emit invisible laser radiation from an open optical port. To avoid possible eye damage
do not look into an open optical port during laser operation. Do not exceed specified operating limits.

Absolute Maximum Ratings

Absolute maximum limits mean that no catastrophic damage will occur if the product is subjected to these ratings for short periods, provided each
limiting parameter is in isolation and all other parameters have values within the performance specification. It should not be assumed that limiting
values of more than one parameter can be applied to the product at the same time.
