(Nasdaq: APAT) announced today it had received notice from a customer canceling an order for its 16 channel, 50 Gigahertz (GHz) spacing dense wavelength division multiplexer/demultiplexer (DWDM) components. The customer cited concern over the time required to deliver qualified components and a potential conflict with its production schedule requirements as reasons for withdrawing the order, valued in excess of $500,000. "We are very disappointed by this development," said Anil Jain, the president and chief executive officer of APA Optics. "While we continue to make progress toward Telcordia GR1209 qualification, the customer determined that, based on our current status, the time required to achieve qualification didn't fit with its production schedule," said Jain.
