50G-PON Gets Testing Debut at Broadband Forum Interoperability ‘Plugfest'
The latest Broadband Forum 'Plugfest' marked the first time that 50G-PON – or Higher speed (HS-PON) – were tested at the interoperability event series, and the second time for 25GS-PON. The Plugfest was held in conjunction with LANPARK and AT&T Labs ' at the latter's Plano, Texas facility.
Some of the biggest fiber technology vendors gathered to test the interoperability of their PON (Passive Optical Network) equipment with emulated networks. Participating companies included Adtran, Broadcom, Calix, CIG, Cortina Access, Gemtek, Lambda Networks, MT2, Nokia, Sagemcom, and Vantiva.
'It's crucial that the industry prioritizes interoperability, co-existence, and collaboration to help broadband service providers excel with the next generation of PON technologies,' said Broadband Forum CEO Craig Thomas. 'Following the success of the previous Plugfest, it was great to see the industry come together again to advance both 25GS and 50G-PON technologies thanks to the participation of the vendors and involvement of LANPARK and AT&T Labs.'
The aim of the latest Plugfest, part of a multi-year interoperability testing series in laboratories around the world, was to give vendors an opportunity to ensure their equipment is interoperable with and ready to be deployed when connecting homes and businesses to broadband service providers' core networks.
The Plugfests are open to vendors of optical line terminal (OLT) and optical network unit (ONU) equipment, PON chipsets and software stacks, Residential Gateway devices directly incorporating a PON interface, and test and measurement equipment.
'During the Plugfest, AT&T Labs emphasized the importance of interoperability in diverse operator networks to enable a multivendor broadband ecosystem,' said Sumithra Bhojan, Director-Member of Technical Staff at AT&T Labs. 'This is critical as PON technologies evolve. The Broadband Forum plays a key role in fostering collaboration among operators, silicon, optics, software, and equipment suppliers, ensuring seamless integration and innovation across the ecosystem.'
'At each Plugfest, we see significant interoperability improvements between the products presented by manufacturers,' said Thierry Doligez, CEO of LANPARK. 'This demonstrates the importance of these testing events and the relevance of the PON interoperability program conducted by the Broadband Forum.'
25GS-PON TC-PMD Layer was tested for the second time at a Plugfest and, for the first time, 25GS-PON OMCI and 50G-PON TC-PMD Layer was tested – signaling the industry's intent to be prepared to supply future fiber networks. Feedback from participating vendors has been instrumental in refining test plans, organizing future Plugfests, ensuring continued program improvement, and the overall success of the test events.
The next Broadband Forum PON Plugfest will be hosted by the LANPARK Laboratory in Tours, France, from July 7 to 10, 2025. The Plugfest will test XGS-PON, 25GS-PON, and 50G-PON.

Investors Should Still Avoid Verizon Stock Despite Rising Earnings. Here's Why.
Key Points Verizon's already massive debt has risen further this year. Verizon now has to balance expectations of dividend increases against its generous yield. Reducing or suspending its dividend to focus on debt reduction could help Verizon stock longer-term. 10 stocks we like better than Verizon Communications › On the surface, Verizon Communications (NYSE: VZ) released a solid earnings report for the second quarter of 2025. The company benefited from rising revenue, earnings, and free cash flow, and a raised outlook bodes well for the communications stock's progress. What the report did not do is alleviate concerns about one area of the balance sheet where the company has struggled for years. That strongly indicates that without one painful but critical move, Verizon stock will likely continue to struggle. Verizon's ongoing concern Verizon's situation worsened in one key area: total debt. As of the midpoint of 2025, Verizon's total debt now stands at almost $146 billion. This is up from $144 billion at the end of last year as its unsecured debt, which typically carries higher interest rates, rose by $2 billion. However, when factoring in the total equity, or book value, of $104 billion, it becomes apparent how much strain these obligations place on the balance sheet. Admittedly, Verizon and its main competitors, AT&T and T-Mobile, have also depended heavily on debt to finance the construction and maintenance of their telecom networks. Verizon's debt was more manageable until 2021, when the company spent $52.9 billion to acquire C-band spectrum. Spectrum is a sort of "RF real estate" that grants Verizon the exclusive right to use a specific frequency in a geographic area. This was prime spectrum, which enabled many of its wireless service offerings. So why is the debt an issue? Indeed, the debt level itself is not necessarily an issue. Over the previous 12 months, Verizon spent $6.6 billion in interest expenses. This amounts to a slightly more than 4% in interest costs when factoring in the $154 billion in total debt, a relatively low rate. Nonetheless, interest rates have risen since 2021. Even though only around $2 billion of Verizon's debt is due this year, it will likely have to refinance that debt at a higher interest rate, meaning investors should assume that the cost will rise over time if its financial situation remains the same. Another factor is its dividend sustainability. Verizon has built an 18-year streak of payout hikes and likely wants to avoid the fate of AT&T, whose stock suffered for years after it abandoned a 35-year record of annual dividend increases in 2022. Verizon's dividend returns are also significantly above those of its peers. At $2.71 per share, its dividend yield is 6.4%. That is more than 5 times the S&P 500 average of 1.2%. It is also significantly higher than the yields of AT&T and T-Mobile, which return 4.1% and 1.4%, respectively. That dividend cost Verizon nearly $11.4 billion over the last 12 months. In a sense, it can cover this cost since it generated just over $20.1 billion in free cash flow during the same period. Still, with a dividend cut, Verizon could also use some or all of that $11.4 billion to retire debt. So far, Verizon has not done that, as its high yield likely makes the stock a draw for income investors. Also, if AT&T and other stocks are any indication, a dividend cut could lead to stock price declines in the near term. Nonetheless, lower debt levels would help stabilize the balance sheet. Over time, this could make the stock more attractive, as it has underperformed the market despite trading at a P/E ratio of 10. Income investors would suffer from both lower dividend income and falling stock prices in the near term. Conversely, the low P/E ratio may limit the downside. The improved finances could draw investors to the stock, possibly compensating for the lost dividend income in the long run. Making sense of Verizon stock Even with the positive earnings report, Verizon stock is likely a hold for now. While its dividend is generous, its high cost to the company and heavy debt burdens likely make the dividend's current trajectory unsustainable. That will lead to more struggles for Verizon stock if it lowers the dividend to better service its debt. However, investors should also note that AT&T remains a solid dividend stock despite slashing the payout. That indicates that as investors adjust to a new reality, rising earnings, a stronger balance sheet, and a low P/E ratio could make Verizon stock an attractive holding if it works harder to lower reduce its debt.

AT&T's CFO and CMO have key advice on how to think about marketing
Good morning. Traditionally, many CFOs viewed marketing as a cost center, but more are now seeing it as a growth accelerator. AT&T (No. 37 on the Fortune 500) illustrates how finance and marketing can work together to support business expansion. I sat down with Pascal Desroches, AT&T's senior EVP and CFO, and Kellyn Smith Kenny, chief marketing and growth officer, to learn more. CFOs often have a reputation for saying 'no' to new marketing ideas, but Desroches has taken a different approach in his career. 'You can't be in an organization where everybody's terrified of the CFO—it just doesn't work,' he told me. Desroches recalled advice from his mentor, the late media executive Dick Parsons: 'As executives, we have to leave our door open, even for bad news, because it gives us an opportunity to problem-solve.' Kenny agreed. 'I'm working with Pascal to massively overhaul and transform the digital experience for customers,' she said. 'None of that would be possible if Pascal was just saying, 'No,'' she quipped. Desroches approaches every conversation, decision, and investment with an enterprise mindset—how do we help the company succeed? 'But he also holds people accountable, which is exactly what you need your CFO to do,' Kenny added. A focus on the customer Desroches credits his customer-focused perspective to his 20 years in the media industry prior to becoming CFO of AT&T in 2021. Understanding and marketing to consumers was essential, he said. AT&T's marketing team provides insights that shape new products and services. Increasingly, customers prefer a single provider for wireless and broadband, Desroches said. 'Kellyn and her team championed this, and our investments reflect their feedback,' he said. Kenny works closely with Desroches and is a direct report to AT&T CEO John Stankey, solving problems for each business unit within budget, he explained. 'Her ability to deliver results within financial constraints has been incredibly impressive to watch,' Desroches noted. Before joining AT&T in 2020, Kenny served as global CMO at Hilton and held senior roles at Uber, Capital One, and Microsoft. 'In my bones and in my DNA, I'm always thinking about how any marketing investment will drive the company's financial performance,' she said. Shared metrics for growth Research backs the CFO–CMO collaboration. A recent McKinsey analysis of Fortune 500 executive teams, based on publicly available data, found that companies with a single growth-focused executive, like a CMO, grow up to 2.3 times faster. Successful marketing teams use shared KPIs to demonstrate financial impact, making it easier for CFOs to support new initiatives. One of Desroches and Kenny's joint projects—the AT&T Guarantee, introduced in January—promises reliable connectivity, fair deals, and prompt service. If AT&T falls short, it takes corrective action, such as bill credits. 'We anticipated a certain amount of credits, but the actual need has been lower,' Kenny said. She and Desroches credit AT&T employees for reducing outages and keeping customer wait times under five minutes. Since launching the AT&T Guarantee, the company has seen higher net promoter scores (NPS) following network disruptions. Finance and marketing teams jointly track NPS, 'brand love,' and the share of customers who bundle multiple services. Other shared metrics include customer lifetime value, average revenue per account, and churn—which is decreasing among customers who've experienced issues, Kenny said. AT&T also reported on Wednesday that it added 401,000 net postpaid phone connections in Q2, reflecting strong customer growth. A finance person sitting at your leadership team table, 'who is fluent in the practice of marketing and growth, goes a long way,' Kenny said. Have a good weekend.
