News summary:
- Metro and edge aggregation networks need to increase speed and
energy efficiency
- BT Group completes field trial over a live research fiber
network with Adtran’s pluggable 100ZR transceiver
- With high spectral efficiency and low power consumption, the
trial showcases new options for sustainability and scale
Adtran today announced that together with BT Group it has
conducted Europe’s first successful field trial of optical
transport in a live research network, using Adtran’s Coherent 100ZR
pluggable transceiver. Achieving high levels of spectral efficiency
and low power consumption, the trial demonstrated the transceiver’s
ability to enable the transport of 100Gbit/s wavelengths, over
longer distances, across routes at metro and edge aggregation
networks, offering scalable and efficient solutions for the
future.

With demand for speed and bandwidth growing, there is a need to
increase the transport capacity of access and edge aggregation
networks. As such, operators need cost-efficient solutions that can
be easily deployed to upgrade certain routes without making major
changes to existing infrastructure.
About the size of a memory stick, the Adtran Coherent 100ZR
transceiver can be plugged directly into an operator‘s transmission
unit. Featuring a purpose-built digital signal processor (DSP)
co-developed with Coherent Corp that is optimized for data rates of
100Gbit/s and designed for easy integration with deployed
infrastructure, the QSFP28-compatible transceiver facilitates the
adoption of 100ZR coherent technology at the network edge.
“Adtran’s plug-and-play solution has enabled us to demonstrate
the feasibility of boosting capabilities within existing networks
and doing so in a cost-effective and scalable manner,” said Andrew
Lord, senior manager of optics research at BT. “As we continue to
innovate and push boundaries, technologies like this will be
instrumental in achieving our goals for a greener, more efficient
telecommunications landscape.”
The trial with BT Group was conducted across a complex network
infrastructure, spanning 90km over a third-party optical line
system, incorporating four ROADM nodes and six amplifiers.
Utilizing a tight 50GHz ROADM channel, the trial achieved enhanced
spectral efficiency. Operating at less than 5 watts, the trial also
set new benchmarks for energy efficiency.
“Together with BT Group, we’ve showcased a method for
transforming network infrastructure with highly efficient,
low-power solutions. It’s a strategy that requires significantly
less equipment and fewer sites. The demo also proves the advantages
of deploying one amplifier in the optical line system rather than
multiple amplifiers within each transceiver module. This
streamlined approach helps boost network performance, reduces
operational spending and shrinks carbon footprint. As well as big
potential savings – as much as 50% in some cases – this strategy
offers a clear path to more sustainable network development,”
commented Ryan Schmidt, GM of optical transport at Adtran. “This
demo also highlights the exceptional performance of our
outdoor-hardened Coherent 100ZR transceiver. Despite its relatively
low optical launch power, it excelled within a complex, real-life
ROADM network.”
