Flood-related Losses	3 Months Ended

Flood-related Losses [Abstract]
Flood-related Losses [Text Block]	Flood-related Losses As previously disclosed, 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. We are evaluating the flooding situation in Thailand on an ongoing basis. 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. We agreed to reimburse our contract manufacturer using insurance proceeds that we expect to receive. Purchase orders have been issued to replace the damaged process and test equipment and new equipment is now being received. We are making significant progress and the rebuild plan is on schedule. Between our own facilities and those of our contract manufacturer, we expect the rebuild of our CATV production line to be completed by the end of March 2012 and the rebuild of our telecom-related production line to be completed before the end of May 2012. We are working closely with customers on our recovery manufacturing plan to align with their needs. Our ability and the time required to recommence operations will be affected by the extended lead-time required to replace damaged equipment and complete customer product qualifications. 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 may delay or adversely impact 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 $0.9 million of inventory on order related to manufacturing product lines that were destroyed by the Thailand flood and will not be replaced. This expense was recorded within cost of revenue on our statement of operations. A significant portion of our finished goods inventory was moved to the second floor of the Thailand facility before the flood waters reached the manufacturing floor. This has allowed us to serve the near term demands of our customers. Our major focus is to work with our customers to meet their near term needs and to ascertain that the demand will still be there for our products when we are back to full capacity. During the three months ended December 31, 2011, we signed agreements with certain customers related to our Fiber Optics segment pursuant to which they will receive an allocation of our finished goods inventory that was not damaged by the Thailand flood, as well as a percentage of future output from our new production lines being placed into service during fiscal 2012. As consideration, we received $6.4 million through December 31, 2011 as partial prepayments for future product shipments. These advanced payments will be used to support our working capital requirements and purchases of manufacturing equipment. 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. 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.
