Aussie
Broadband
has
added
400Gbps
backbone
links
between
Sydney
and
Melbourne.
The
broadband
retailer
has
been
trialling
Telstra
Wholesale’s
400Gbps
Ethernet
services
on
two
diverse
links:
a
coastal
path,
and
an
inland
path,
both
connecting
multiple
data
centres
along
the
way.
Aussie
Broadband’s
chief
technology
officer
and
co-founder John
Reisinger said
the
links
will
help
the
company
grow
its
footprint,
with
redundancy
making
customer
services
more
resilient.
“Aussie
Broadband
is
the
first
client
to
adopt
Telstra
Wholesale’s
native
400Gbps
wavelengths,
rather
than
stacking
multiple
100Gbps
services,”
Reisinger
said,
adding
that
the
provider
is
looking
to
acquire
more
links
as
demand
for
capacity
increases.
“The
additional
capacity
helps
Aussie
better
handle
localised
content
network
outages,
which
can
sometimes
result
in
hundreds
of
gigabits
per
second
having
to
be
carried
to
alternate
locations.”
Telstra
has
been
working
on
the
400Gbps
backbone
upgrade
since
July
2022,
when
Ericsson
began
installing
Ciena’s
6500
packet-optical
system
into
the
network.
Telstra
Wholesale
said
the
upgrade
“quadruples
the
data
capacity
transmitted
per
client
service
wavelength”.
“Data
traversing
over
the
Telstra
fixed
network
has
tripled
since
2017
and
continues
to
grow
at
about
25
percent
each
year,” Telstra
Wholesale
executive Steve
Long
said.
Telstra
Wholesale
expects
to
release
the
400Gbps
service
to
all
customers
in
April,
and
during
2023,
the
service
will
be
made
available
on
other
inter-capital
routes.
