BT Group trials Adtran's coherent 100ZR transceiver

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.

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.
