Alliance Fiber Optic Products, Inc. (Nasdaq:AFOP), an innovative supplier of fiber optic components, subsystems and integrated modules for the optical network equipment market, today raised its guidance for net sales for the quarter ended June 30, 2012.

For the 2nd quarter of 2012, the Company expects to report net sales above $11.5 million, exceeding the previously stated revenue guidance in the first quarter conference call. The Company's higher than anticipated net sales in the second quarter of 2012 primarily reflects stronger than expected bookings from key customers and continuous business progress achieved in the first half of YR2012. The Company's quarterly profits are expected to improve significantly, compared with the previous quarter, as well.

A more detailed review of second quarter financial results as well as the outlook for the third quarter of 2012 will be provided, when complete second quarter results are discussed on a conference call at 1:30 p.m. (Pacific) on July 24, 2012.
