JDS Uniphase (JDSU) CFO Ron Foster has given his two-week notice.

Foster, the top finance officer for the San Jose, Calif., optical networking parts maker, plans to leave the company at the end of the month, according to a press release issued Friday. Foster had been with JDS for two years. The release didn't specify a reason for his departure.

"All of us at JDS Uniphase appreciate Ron's contributions and service," CEO Kevin Kennedy said in the release.

Dave Vellequette, the company's operations controller, will handle the senior financial duties until a replacement can be found.

JDS has been through a lengthy cost-cutting process in the wake of the Internet-equipment boom and bust, and has been somewhat on the mend financially with a promise to return to profitability. But last month, the company disappointed investors anew by cutting its financial targets for the current quarter.

JDS said that it expected an adjusted net loss in the fiscal third quarter ending in March of 2 cents a share on sales of about $160 million. Analysts had expected a penny-a-share loss on $184 million in revenue, according to Reuters Research.

Shares fell 3 cents to $1.88 in after-hours trading Friday.
