Riding the coherent revolution

25/11/2024

In the ever-evolving landscape of telecommunications, the pursuit of faster, more reliable and efficient data transmission has been a constant driving force. At the forefront of this revolution are 100G 0 dBm coherent modules, representing a remarkable leap forward in optical communication technology. Here we explain how the latest coherent modules are changing the face of telecoms.

According to PwC’s Global Telecom Outlook, global data consumption over telecom networks will nearly triple, from 3.4 million petabytes (PB) in 2022 to 9.7 million PB in 2027, driven largely by video traffic. As the demand for data continues to surge, the need for more advanced data transmission technologies has become increasingly critical. Traditional optical communication systems, while reliable, are approaching their limits in terms of bandwidth and speed. This is where 100G 0 dBm coherent modules emerge as a transformative solution for telecom providers.

100G coherent modules utilise advanced digital signal processing (DSP) and sophisticated modulation techniques, such as Quadrature Phase Shift Keying (QPSK) to achieve a data transmission rate of 100 gigabits per second (Gbps) over a single wavelength. The 0 dBm designation indicates that the module’s output power is zero decibels relative to one milliwatt (mW). This specific power level is optimal for enabling brown field deployment, while the performance of  the transceiver makes it suitable for short and metro range as well as in specific condition for long-haul applications.

Advantages of 100G 0 dBm coherent modules

The transition to 100G coherent technology presents several significant advantages over conventional optical communication methods.

Firstly, 100G 0 dBm coherent modules significantly increase the capacity for data transmission. By enabling the transmission of data at 100 Gbps over a single wavelength, these modules effectively multiply the capacity of existing fiber infrastructure.

Another major advantage is the ability to extend transmission distances without the need for signal regeneration. Traditional optical networks often face signal degradation over long distances, requiring the installation of additional equipment to regenerate the signal. This not only adds complexity to the network but also increases operational costs. In contrast, 100G 0 dBm coherent modules maintain signal integrity over vast distances, thanks to advanced Forward Error Correction (FEC) algorithms and coherent detection techniques. Distances of over 2,000 km can be achieved without the need for regeneration, making these modules ideal for long-haul and submarine cable systems.

Moreover, 100G 0 dBm coherent modules are built into QSFP28 form factor transceivers with a power consumption of less than 5.5W, which make this solution suitable for use with existing switches and routers, without the need to upgrade existing infrastructure with QSFP-DD ports.

In terms of operational efficiency, the energy consumption of 100G 0 dBm coherent modules is notably lower than that of their predecessors. Operating at 0 dBm output power, these modules consume less power, contributing to reduced operational expenses. This energy efficiency is becoming increasingly important as telecom operators seek to minimise their carbon footprint and align with global sustainability goals.

Transforming telecom networks

The deployment of 100G 0 dBm coherent modules is not merely about upgrading existing networks; it represents a fundamental transformation of the telecom landscape. These modules enable telecom providers to expand their network coverage, reach underserved areas and improve service quality for customers.

One of the most profound impacts of this technology is seen in the deployment of 5G networks. The rollout of 5G requires high-capacity, low-latency connections, and 100G 0 dBm coherent modules are ideally suited to meet these requirements. By integrating 100G coherent technology into their networks, telecom operators can support the next generation of mobile services with unparalleled reliability and speed.
