Product Capabilities and Value
With the growing need for bandwidth, system designers are packing as
many channels as possible into their DWDM systems. Their design goals
place increasingly stringent demands on all the filtering components
used in the system, demands such as very low insertion loss, wide
channel passband, and low crosstalk.
WaveSplitter was one of the first to bring an interleaving product to
market with its WaveProcessor F³T Interleaver, addressing the need
for more bandwidth by interleaving multiple sets of optical channels
into a single, densely packed stream. This enables higher bandwidth in
existing networks and allows network upgrades and developments such as
the introduction of ultrahigh transmission speeds in long-haul systems.
The WaveProcessor's design is based on an all-fiber flat-top channel
response, which enables low insertion and polarization-dependent loss,
low dispersion and high channel isolation over a passband greater than
50 percent of the channel spacing. A flat-top interleaver allows for
drift in system laser sources without significant degradation in signal
transmission performance. This approach is designed to give
telecommunications systems developers and integrators a high degree of
flexibility and scalability in meeting existing and future bandwidth
capacity requirements. Its active-temperature control design provides
enhanced center wavelength accuracy over an operating temperature range
of 0 to 65 °C, which is especially important as the channel spacing is
reduced.
In addition to the above application, the F³T Interleaver can be
used for multichannel optical add/drop multiplexing in networks. The
low dispersion performance of the WaveProcessor is especially important
in all-optical networks where the signal passes through multiple
components without regeneration.
Finally, the WaveProcessor Interleaver was recently awarded the
Photonics Circle of Excellence Award, which recognizes the 25 most
technically innovative new products of the year. WaveSplitter's
WaveProcessor Interleaver was included as one of only five passive
components designed for advanced telecommunications networks.
