MINNEAPOLIS -- APA Optics (Nasdaq: APAT - News) announced deliveries of its 8 channel 200 GHz spacing multimode fiber (MMF) based DWDM mux/demux components. The components are used for multimode fiber optic networks and other applications that use multimode transmission or benefit from multimode fiber in the receiver. The 62.5 micron core, multimode fiber based DWDM design is based on APA's patented high frequency bulk diffraction grating based platform and builds on the company's experience in design, assembly and test of both singlemode and 50 micron core multimode fiber based DWDM with several modifications. In particular, the 62.5 micron MMF model has significantly lower and more uniform channel-to-channel insertion loss and larger bandwidth due to its broader flat-top passband. Additionally, the new DWDM has negligible fluctuations with time and temperature due to its improved optical characteristics. The 62.5 micron MMF DWDM will also work with 50 micron multimode fiber as well. "We are extremely pleased with the performance of these devices," reports Anil Jain, APA Optics president and CEO. "Multimode fiber will find applications in the growing access and 'last mile' segments of the optical communications market, as opposed to the currently depressed long haul segment. Nevertheless, we are cautious about the near term potential given the current state of the optical communications market. We need more time to see if sufficient commercial demand for the product can be generated at acceptable price points." APA Optics Inc.
