Sanchez had served in several financial executive positions at SDL, an optical systems shop acquired by

Avanex also promoted Yves Le Maitre as its chief marketing officer.

The shakeup comes just three days before the Fremont, Calif., tech outfit is scheduled to report fiscal first quarter earnings.

Shares of Avanex sank a penny to $1.63 in after-hours trading Monday, while rival



slipped 12 cents in regular action to $3.30.
