AllWare
fiber is ITU-T G652.D compliant. AllWave Zero Water
Peak (ZWP) single-mode optical fiber is the industry's
first full-spectrum fiber designed for optical transmission
systems operating over the entire wavelength range
from 1280 nm to 1625 nm. Before AllWave ZWP fiber
was introduced, systems operated in either the O-band
(1310 nm window) or the C-band and L-band (1530 nm
to 1625 nm). Today, with AllWave ZWP fiber, the E-band
(1400nm window) is available to expand the capacity
of optical networks. It is an excellent platform for
cost effective Coarse Wavelength Division Multiplexing
(CWDM).
AllWave
ZWP fiber enables use of the entire optical fiber
spectrum thanks to a manufacturing process the virtually
eliminates the high attenuation, or water peak, that
typically occurs in conventional single-mode fiber
due to hydroxy1 (OH) absorption in the E-band of the
fiber. The removal of the water peak is permanent,
and the attenuation of AllWave fiber at 1400 nm is
always lower than at 1310 nm.
The
dispersion characteristics of AllWave fiber at 1400
nm are ideal for high data rates, such as 10 Gb/s
applications. By removing the water peak, not only
does AllWave fiber open up the E-band for communication,
but it is ideal for high-speed networks. Increased
usable wavelengths, ideal dispersion characteristics
and tremendous flexibility for network design make
AllWave fiber the choice.
Why
AllWave fiber for metropolitan local and access network?
Metropolitan
local and access networks are made up of many different
architectural designs,such as ring, mesh, and hybrid
fiber coaxial (HFC) networks. They support many different
applications, including 10 Gigabit Ethernet, Internet
Protocal (IP), Asynchronous Transfer Mode (ATM) and
Synchronous Optical Network (SONET), using single
channel, Dense Wavelength Division Multiplexing (DWDM)
and Coarse Wavelength Division Multiplexing (CWDM)
transmission. Finding an ideal, low-cost fiber solution
for all these architectures and applications is not
easy. AllWave fiber helps network planners and operators
to build cost efficient, high-speed metropolitan optical
networks with unique characteristics as shown to the
right in "Features".
These
unique characteristics translate into greater information
capacity with maximum flexibility and lower total
system cost for metroplitan and access networks.
When designing today's network, look for the fiber
that will provide you the greatest capacity and
flexibility both now and in the future.
