Flood-related Losses [Abstract]
Flood-related Losses [Text Block]	Flood-related Losses In October 2011, flood waters infiltrated the offices and manufacturing floorspace of our primary contract manufacturer's facility in Thailand and suspended all production. The areas used to manufacture our fiber optic products and our process and test equipment were submerged in flood water that was several feet deep for more than a month. As a result, the manufacturing infrastructure that supported approximately 50% of our Fiber Optics segment revenue was destroyed. This has had a significant impact on our operations and our ability to meet customer demand for certain of our fiber optics products in the near term. Our Photovoltaics segment was not affected by the Thailand floods. Production capabilities for three major product lines were impacted. These include (i) telecom products, such as tunable lasers and our high-volume tunable XFP line (our low-volume TXFP production line is located in the U.S. and continues to produce products), (ii) cable television (CATV) laser components and transmitters, and (iii) other legacy products. Over the past several months, we have been developing and implementing alternative manufacturing plans in our own facilities in China and the U.S. to meet our customers' short-term demands. Concurrently, we have been focusing on rebuilding the high-volume production infrastructure for impacted product lines at other locations owned by our primary contract manufacturer in Thailand, as well as our own manufacturing facility in China. Our focus during the rebuild is on a quick recovery and strategies to better configure the equipment for efficiency, reduce our cost structure, and provide manufacturing diversification. The equipment we used at the Thailand facility was highly sophisticated and complex. In November 2011, we entered into an agreement with our contract manufacturer in Thailand whereby our contract manufacturer will purchase equipment to rebuild our affected manufacturing lines which is expected to cost approximately $5.7 million. We agreed to reimburse our contract manufacturer using insurance proceeds that we expect to receive. We are making significant progress and the rebuild plan is on schedule. We have rebuilt our own CATV production line and expect that it will be at full capacity in June 2012. Our contract manufacturer is rebuilding our telecom-related production lines which are expected to be completed in June 2012. We are working closely with customers on our recovery manufacturing plan to align with their needs. Gross margins will continue to be negatively impacted in subsequent quarters until we are able to substantially restore operations, the supply chain infrastructure is re-established, and we regain any lost market share. The flooding has delayed our development and introduction of new fiber optics-related products and technologies. Delays in implementing new technologies and introducing new products may reduce our revenue and adversely affect our consolidated results of operations even after operations are restored. Instead of completely rebuilding all flood-damaged manufacturing lines in Thailand, management has decided to realign the Company's fiber optics product portfolio and focus on business areas with strong technology differentiation and growth opportunities. Management identified certain inventory on order related to manufacturing product lines that were destroyed by the Thailand flood and will not be replaced. This expense, which totaled $0.4 million and $1.3 million for the three and six months ended March 31, 2012, respectively, was recorded within cost of revenue on our statement of operations. We are working closely with our contract manufacturer to identify all flood-damaged assets of the Company. During the three months ended December 31, 2011, we recorded estimated flood-related losses associated with damaged inventory and equipment of approximately $3.9 million and $1.8 million, respectively. During the three months ended March 31, 2012, we recorded an additional $0.1 million related to flood-damaged inventory. Equipment under capital lease totaling $1.9 million as of September 30, 2011 was also damaged by the Thailand flood and written off against our outstanding capital lease obligation. We continue to evaluate our preliminary estimates of flood-related losses, and in future quarters we may record additional adjustments for damaged inventory and equipment. Our contract manufacturer is required under its production agreement with us to reimburse us for losses to inventory and equipment incurred while at their facility. We are working with our contract manufacturer (and our contract manufacturer's insurance carrier) to receive insurance proceeds to cover the direct damages to our assets that were impacted by the flood. We are not a named beneficiary of our contract manufacturer's insurance policy. The timing and amounts of the recovery from the contract manufacturer, including insurance proceeds, are uncertain at this time. Insurance recoveries related to inventory and equipment destroyed by the Thailand flood will be recognized to the extent when they become probable and realized. Additionally, we also claimed damages and received proceeds of $5.0 million under our own comprehensive insurance policy relating to business interruption and we recorded this amount as flood-related insurance proceeds during the three months ended December 31, 2011. No additional business interruption insurance proceeds associated with this event are anticipated.
