Submarine cable system is the “highway” of the Internet. R ~Nets (Resonant Networks) is humbled to be selected for the important task of testing these cable systems. Also known as fibre characterisation, cable testing requires fundamental knowledge of optical fibre science and in-depth technical know-how. This is especially crucial in submarine cable transmission systems. In addition, field operations know-how is critical so as not to damage the optical fibre system and ensure accurate engineering results are obtained to validate the system design. One of the challenging projects we have undertaken involved fibre characterisation work for an ultra-long haul repeaterless submarine cable over 350km. By utilising special test equipment alongside efficient project management to deploy the resources to very remote locations, the test results were successful in producing a well-designed optical transmission system connecting Internet users all over South East Asia.

A world-class port operator, built a state-of-the-art infrastructure to improve port operations, such as achieving zero emissions and a fully automated electric yard crane system. Automating port operations requires network connectivity that spreads over a very large area similar to a wide campus environment, non-stop availability and a high-performing network infrastructure. As their partner for this large scale project, we successfully implemented DWDM (Dense Wavelength Division Multiplexing) with ROADM (Reconfigurable Optical Add-Drop Multiplexer) ring networks. This ROADM ring network is currently one of the largest in South East Asia. As a result, our client was able to gain a 6-fold increase in productivity, thanks to the new remote capability in operating the electric cranes.

In economic and business terms, the ‘network effect’ is a phenomenon whereby a good or service becomes more valuable with increased usage. We are seeing this same effect in the Internet. With its increasing flood of users and digital innovations, Internet has become a key dynamic behind many business successes. Following this effect, data centres are also requiring larger bandwidths and higher performance. R ~Nets has helped enterprises, cloud and data centre operators implement high throughput (100Gbps and beyond), resilient (less than 50ms recovery time) and privacy protected (encrypted) optical networks in numerous green and brown field network projects. Thanks to our IT Infrastructure operations experience and risk management framework, our clients benefited in zero defect implementations and quality post project support.

A typical electrical transmission tower is about 50m in height. Hence it is protected from the usual field operations problem of cable cut for long haul optical fibre system. However such setup requires the optical fibre to be specially tested, assessed and selected to properly support long haul DWDM transmission. This is due to many affecting factors such as temperature, wind loading and mixing dissimilar single-mode optical fibres, which can severely impair DWDM transmissions. By understanding client requirements and drawing on years of optical engineering know-how, R ~Nets had tested and implemented DWDM systems over high voltage electrical transmission towers beyond 150km in certain spans.

Going digital has allowed the Financial Services Industry (FSI) to expand its distribution and reach in the shortest times. FSI is arguably the industry with most potential for digitisation. Banks can now eliminate their physical footprint and still reach large numbers of people, greatly enhancing service value such as enabling global money transfer within seconds. Digitisation also helps FSI to significantly improve cost-income ratio and income-generating opportunities. R ~Nets has enabled many banks to meet digitisation demands in the FSI by helping them implement high performance optical networks. One such project was a complex, encrypted global Optical Transport Network (OTN) using DWDM system – a ground-breaking feat that may be the first in the world. Dissimilar DWDM systems from different telecom providers were successfully integrated. The result is a next-gen global network, which harnesses the ability to carry multiple services in a single physical interface with encryption but without sacrificing throughput, thus allowing our client to effortlessly maximise their global investments.
