A huge well done to all our incredible JSM employees who took part in the Thames Bridges Trek this weekend!

Together, they’ve raised an amazing total of £4430 so far for the Dragonfly Cancer Trust, supporting young cancer patients across the UK.

We chose this challenge not just for its scenic route, but because it holds special meaning for us. JSM Group was founded in London in 1998, and our early success came from being one of the few companies with the expertise to deliver complex utility infrastructure projects in the capital’s challenging urban landscape. Walking across the very bridges that span the city where our journey began made this trek especially meaningful.

Congratulations to all the employees for completing the trek and a massive thank you to everyone who has donated to such an incredible cause.

As part of JSM Group’s ongoing commitment to charitable initiatives, two of our colleagues, Samantha Monk and Doug Monk, are gearing up for the Thames Bridges Trek 2025, a 25km challenge through the heart of London in support of the Dragonfly Cancer Trust. 

We asked them a few questions about their motivations and preparations for the event: 

What inspired you to sign up for the Thames Trek?
JSM have kindly provided grants to a couple of causes that are important to us over the years and so we were keen to give something back. It also gave us an incentive to increase our fitness and get outside more whilst raising money for a fantastic cause. 

Have you ever done a charity walk or trek before? 
Doug has taken part in half marathons and an SAS ultra challenge previously; however, this is the first time for both of us taking part in a trek. 

What are you most looking forward to about the day? 
We are looking forward to the physical challenge, engaging with colleagues that we haven’t previously encountered, and the sense of achievement (and beverages) at the finish line. 

How have you been preparing for the trek – any training or gear tips?
We have been increasing our walking distances over a period of weeks since signing up; the kids and the dogs have never had to walk so far in their lives and will probably be glad when it’s over. 

12 JSM employees are proudly taking part in the trek to raise funds for Dragonfly Cancer Trust, with an impressive £2,550 raised so far! This is just one example of JSM’s ongoing commitment to giving back. The company has already donated over £6,334 to charitable causes this year alone. If you’d like to support the team’s efforts, donations can be made here.

We’re proud to support their journey and wish them all the best as they take on this inspiring challenge. Keep an eye out for updates and photos from the day!

We extend our warmest congratulations to the winner and a heartfelt thank you to every child who participated. Your creativity and care are helping build safer communities, one drawing at a time.

For more than twenty years, JSM Group has delivered fibre optic connectivity across the United Kingdom. Our telecoms division has supported rural broadband programmes, national fibre roll outs and the extremely low latency networks needed by financial institutions and data centre operators. As demand for bandwidth and speed continues to grow, the industry is now looking towards the next major step forward. That technology is Hollow Core Fibre, often referred to as HCF. In this article, Telecoms Director Daniel Rowan explains what HCF is, why it represents a significant change, and how it aligns with JSM Group’s forward looking approach to digital infrastructure.

What Is Hollow Core Fibre?

Hollow Core Fibre replaces the solid glass core found in traditional fibre with an air filled central channel. Light travels faster through air than through glass, which results in noticeably higher transmission speeds. In practical terms, this can reduce latency by up to half when compared with standard single mode fibre. This improvement makes Hollow Core Fibre attractive in situations where even small delays matter. These situations include high frequency trading, real time data analytics and latency sensitive AI applications. Further advantages of HCF include:
  • Significantly lower signal attenuation in advanced designs 
  • Reduced need for repeaters on long distance routes 
  • Better tolerance of high optical power levels 
  • Reduced nonlinear effects that often disrupt dense wavelength division multiplexing 
  • Lower signal dispersion, creating cleaner and more stable transmission 
  • Enhanced resistance to temperature changes and radiation, which is particularly valuable in underground ducts 
  • Improved security, as the air core design makes interception more difficult 
These characteristics help to support very high bandwidths while improving reliability and reducing energy consumption.

Practical Uses in Data Centres and AI Connectivity

Hollow Core Fibre is especially valuable in data centres, where very low latency is critical for cloud computing, AI training and real time analytics. Several global operators are already considering HCF to speed up communication between servers and to reduce delays across complex processing environments. HCF also has strong potential for short range links, such as connections between buildings or between racks inside data halls. In situations where traditional fibre begins to limit performance, HCF offers an immediate improvement. Importantly, Hollow Core Fibre can often be integrated into existing fibre networks. Early deployments show that it is compatible with standard optics in many scenarios. This allows organisations to upgrade parts of a network without needing to replace everything. As AI, 6G, edge computing and cloud services continue to expand, the need for fast and resilient data paths will grow. Hollow Core Fibre is expected to become increasingly common as part of modern telecom infrastructure.

Challenges to Consider

Although HCF offers clear benefits, it is still an emerging technology and should be understood in context. Current limitations include:
  • Higher manufacturing costs than standard fibre 
  • Greater sensitivity to bending, which requires careful installation 
  • The need for continued research and development to refine the design and further reduce loss 
Even with these challenges, industry interest remains strong due to the clear performance gains and long term advantages.

What This Means for JSM Group

JSM Group is committed to supporting the next generation of telecom networks across the United Kingdom. Hollow Core Fibre aligns closely with this commitment. Our teams can support clients with route design, installation, splicing, testing and integration into existing networks. We believe Hollow Core Fibre will play an important part in building faster, more reliable and more secure digital infrastructure for future applications, including AI, automation, smart cities and high capacity data platforms. What we are seeing today is more than an incremental improvement. It is a shift towards a new model of connectivity that places speed, efficiency and reliability at the forefront of modern communication.
At JSM Group, we believe in the power of community and recently, one of our own reminded us just how impactful that belief can be.  Danish Khan, Senior Quality Improvement Manager, proudly represented JSM Group in the Palace-to-Palace charity ride, cycling from Buckingham Palace to Windsor Castle in support of The King’s Trust. This inspiring event wasn’t just about the miles covered- it was about the lives touched.  Thanks to the generosity of our colleagues and the backing of our Community Grant Initiative, Danish surpassed his fundraising goal, raising an incredible £725 (+£116 Gift Aid). These funds will go directly toward empowering young people across the UK. To put this into perspective: 
  • 3 laptops could be provided to help young people re-engage with education and work. 
  • 8 employability courses could be sponsored to build future-ready skills. 
  • 13 one-to-one mentoring sessions could be delivered to boost confidence and resilience. 
Danish shared:
“It was a profound and much-needed experience, reminding me how powerful community and compassion can be, especially in times when finances are tight.” 
We’re delighted to have supported Danish on this journey and even prouder of the impact this ride will have on young lives. Thank you to everyone across JSM who donated, cheered him on, and believed in the cause. You helped turn miles into meaning. 

At JSM, one way we empower our employees to make a difference in their communities through our Community Grant Scheme. One recent example comes from Natalie Denby, Comms Coordinator at JSM and a dedicated coach, who applied for funding to support her son’s U12 football team, the Teviot Rangers Yellow. 

Thanks to Natalie’s initiative and JSM’s support, the team now has brand-new match day kits for all 14 players, proudly featuring the JSM logo. The kits arrived just in time for the weekend, and Natalie personally packed each one with a label and an inspirational quote before handing them out ahead of the upcoming game. 

The boys were so chuffed and excited to put them on. We’ve even got some money left over to buy subs coats and personalised jumpers to keep them warm this winter. A HUGE thank you to JSM for making this possible for my boys, truly grateful – Natalie Denby, Team coach.

We’re delighted to see how this small act of support has made a big impact. Huge well done to Natalie and the Teviot Rangers Yellow – we’re cheering you on! 

Welcome to our new ‘Bytesized’ series, your go-to for a quick read on hot topics in utility infrastructure. Each article delivers insights to keep you informed, fast.

Survey work was recently carried out at a substation in Lincolnshire, where the team undertook a PAS 128 utility survey to support the development of a new cable route for the client. GPS devices were used to capture mark-ups across the site, and the data collected is being processed into a 2D format to visualise the survey findings.

The activities included both utility mapping and topographical surveying. These provided essential information for cable route planning, including land heights, culverts, drains, and their dimensions. This level of detail was key to identifying landmarks and ensuring the proposed route would be practical and efficient.

Utility mapping also played a vital role in understanding existing infrastructure. It helped confirm what was already documented and revealed previously unknown features that may require further investigation. By undertaking these surveys, the team helped de-risk the project, ensuring that design decisions were based on accurate, site-specific data.

The PAS 128 survey provided a critical foundation for the project. By capturing accurate, site-specific data early in the process, we were able to validate existing records, uncover unknown risks, and inform the design with confidence. This proactive approach significantly reduces the likelihood of costly delays later in delivery. – Madalina Cordea, Pre-Construction Project Manager.

This work formed a crucial part of the early planning phase, laying the groundwork for a safe and effective cable installation into the substation.
