Bhag, I am trying to answer your question:

Currently, due to explosive internet usage, ISP all have big problem to meet data capacity problem. However, deploying new optical fiber line is very very expansive. So people invented DWDM technology. It can transmit multiple data channels in a fiber line. More channel means more data can be transferred. Since DWDM can use the existing fiber line so there is a great cost advantages.

APAT is shipping 50 Ghz DWDM filter. It is the most advanced DWDM device on the market. 50 Ghz means that the channel spacing is 50 Ghz which mean higher channel density. For optical fiber, there are only very small range is linear, only this linear range can be used for data transmit. Therefore, a smaller channel spacing means packing more channels in this linear range. What is the difference between 200 Ghz and 50 Ghz? a 50 Ghz device means that it can pack 4 times more of channels(data too) comparing to the 200 Ghz one. For example, if the bandwidth for the optical fiber is 3000 Ghz, then by using 50 Ghz DWDM device, one fiber can transmit 3000/50=60 channels of data but for 200 Ghz DWDM device, it can only transmits 3000/200=15 channels of data. Assume that the data capacity for each channel is the same then the 50 Ghz DWDM device can transmit 4 times more of data comparing to the 200 Ghz DWDM device for the same fiber line. Currently, 50 Ghz DWDM device could pack 64 channel into one fiber. It is selling very very hot and very few people can make it.

Hope it helps

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.
