Most of the hot trends in telecom transformation are software-based -- software-defined networking (SDN), network functions virtualization (NFV), orchestration, automation, software-defined wide area network (SD-WAN), analytics, edge/fog computing, network slicing and more.

Yet hardware isn't completely out of the picture. Operators are evolving the fiber access infrastructure that will be the foundation of the transformed network. A confluence of drivers and enablers lead to evolving business models and architectures for the fixed access infrastructure and renewed investment in fiber access networks.

Difficulty in building a compelling business case for new access fiber helps feed the digital divide. Part of the problem has been that large operators historically tended to silo their access fiber assets along the lines of their internal organizational silos. Thus, there were purpose-built fiber networks for fiber-to-the-anything (FTTx), business services, and wireless backhaul/fronthaul/DAS. These practices are sub-optimal from a capex and opex perspective.

More importantly, fiber access network builds that are considered not viable -- based on the revenue projections and risks of one business -- are often viable if based on revenue projections and risks of multiple businesses. By not sharing infrastructure, operators forego revenue-generating opportunities and good margins.

Acute needs for 'x-haul' for 4G mobile densification and 5G, Internet of Things (IoT), business services upgrades and Gigabit broadband is driving a resurgence in access fiber construction. Operators have come to recognize the inefficiency of siloed infrastructure. A converged, fiber-based fixed access platform has become a strategic necessity.

A new Heavy Reading report, Converged Access Infrastructure, examines the trend toward converged infrastructure in the access network, exploring:

  • Evolution of the fiber access network, past and future

  • Drivers and enablers for access network convergence

  • Financial models for building new access infrastructure

  • How innovation in the outside plant reduces capex for new construction

  • Architectural trade-offs for converged access

  • Why converged access is joined at the hip with SDN/NFV/white box and XGS-PON/NG-PON2

  • Strategic implications for operators, vendors, local governments and investors

Access network convergence is one of the key trends that will define the network of the 2020s and beyond. While it might not be as visible as some of the others, its impact will last for many decades, and its ultimate demise will be from ageing rather than obsolescence. This infrastructure will be the foundation for 5G, IoT, Gigabit broadband, SD-WAN and other services yet to come.

How Many Years Until Positive ROI?
While this sounds great, the cost of fiber and actual installaton will probably mean it's several years before most telecoms show a positive ROI from this type of investment.

The shift to application and network virtualization by operators and CSPs requires a new generation of multicore processors that are being introduced by many vendors.
In the wake of a damaging cyber attack in 2015, Philip Clayson was tasked with creating a cyber breach remediation plan for over 600 applications across TalkTalk's consumer and enterprise divisions and to deal with the operator's 'tech debt.'
It's still hard to say whether carrier SDN is really a success or a failure, but the needle is moving on SDN commercialization – albeit not as quickly as some might hope.
The most recent Thought Leadership Council (TLC) survey finds that although most communications service providers (CSPs) prefer to have a solid plan in place before moving on a new market trend, it's not looking to be the same for automation, as most CSPs surveyed say they are moving forward without solid plans.
Software-defined wide area network (SD-WAN) is the primary focus for cable in 2018, with fierce competition across the market.

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
