 APA OPTICS, INC. ANNOUNCES SHIPMENT OF 50 GHZ DWDM PRODUCT TO SUPPLIER
 
 RELATED SYMBOLS: (APAT)
 
 MINNEAPOLIS, Feb 2, 2000 /PRNewswire via COMTEX/ -- APA Optics, Inc.
 (Nasdaq: APAT) today introduced a new single-mode fiber dense
 wavelength division multiplexing (DWDM) product that provides narrow
 channel spacing, permitting greater utilization of a given wavelength
 band. The Company reported that it is shipping the new
 multiplexer/demultiplexer research unit to a major international
 supplier of fiber optic networking systems. The product, featuring 50
 gigahertz, or 0.4 nanometer, wavelength spacing, is currently available
 in 8 and 16 channels.
 
 "We are pleased to further broaden our complement of single-mode and
 multi-mode components for the DWDM fiber optics industry," said Anil K.
 Jain, president and chief executive officer of APA Optics. "I am
 delighted to report that product performance equals that of our 100 GHz
 single-mode product, with less than 5 decibels (dB) insertion loss and
 more than 25 dB of adjacent channel isolation."
 
 Jain said that this announcement, following the recent introduction of
 a multi-mode DWDM product, emphasizes the fact that APA is one of a
 very few companies supplying both single-mode and multi-mode MUX/DEMUX
 components. Both single-mode and multi-mode are available with Add/Drop
 capability. "We foresee strong futures for both of these technological
 applications, given the differing needs they address," said Jain.
 
 APA said that it is positioned to begin production of this new product
 at once. "The new 50 GHz unit will be assembled using the same
 production line as the 100 and 200 GHz single-mode and 200 GHz
 multi-mode products," said Terry VanderWert, APA's business manager for
 fiber optic products. "This means that we can offer timely delivery."
 
 The Company's success in developing products with narrow wavelength
 spacing while still maintaining high levels of product performance,
 such as in low insertion loss, is attributed to the patented/patent
 pending diffraction grating technology employed by APA. "This
 technology is ideal for single-mode and multi-mode and well suited to
 higher channel counts and narrow channel spacing," said VanderWert.
