Enhancing Data Center Efficiency in the AI Era

WUHAN, China, Sept. 20, 2024 /PRNewswire/ — Over the past two decades, the rapid growth in the number of Internet users and connected devices has dramatically boosted traffic to global cloud platforms and enterprise data centres. This surge has positioned data centres at the forefront of technological innovation. In recent years, the widespread adoption of AI technology has prompted data centres to evolve toward more efficient computing. As a result, data centre operators worldwide are striving to develop faster, denser, more cost-effective, and more energy-efficient infrastructures.

In the field of short-haul optical communications for data centers, transmission solutions using vertical cavity surface emitting lasers (VCSELs) and multimode fibres (MMFs) are favored for their cost-effectiveness. For 25 Gbaud transmission, OM3 and OM4 fibres have become the dominant choice for link coverage ranging from 70 to 100 meters. However, as data centers transition to higher transmission speeds, the industry is shifting towards the use of 100G/Lane VCSEL transceivers. This shift has introduced new challenges for fibre, the medium for data transmission. Issues such as the central wavelength drift of the light source and bandwidth limitations of traditional OM4 fibre at 850nm or longer wavelengths may lead to a reduction in link transmission distance.

To address these challenges, Yangtze Optical Fibre and Cable Joint Stock Limited Company (hereinafter referred to as “YOFC”) has leveraged its deep technical expertise in MMFs to design the high-performance MaxBand® OM4 Pro/Ultra series of MMFs, specifically tailored for 100G/Lane optical transceivers. These new fibre products enhance the transmission efficiency of data centers.

MaxBand® OM4 Pro: It offers an effective modal bandwidth of over 4700 MHz*km in the 850nm to 870nm wavelength range. This significantly improves the average bandwidth within this range and effectively addresses the issue of reduced transmission distance caused by central wavelength drift.MaxBand® OM4 Ultra: It provides high bandwidth at wavelengths of 850nm to 870nm and 910nm. This meets the demand for 100G/Lane single-wavelength unidirectional and bidirectional transmission over distances of up to 100 meters, significantly enhancing transmission distance for single-channel 100G and Terabit BiDi links.

YOFC’s MaxBand® OM4 Pro/Ultra series of MMFs are fully compatible with existing OM4 and OM5 fibre optic standards, as well as systems based on these standards.

OM4 Pro: Broadened Bandwidth, Future Ready

Traditional OM4 fibre provides high bandwidth at 850nm but is limited in bandwidth for longer wavelengths with a narrow operating window. By expanding the operating window to 850~870nm, YOFC’s MaxBand® OM4 Pro fibre effectively compensates for signal degradation resulting from wavelength shifts in optical modules. This ensures high-quality signal transmission, reduces connectivity costs for AI data centers, and enables a seamless upgrade for data center multimode connectivity solutions to 400G, 800G, and higher speeds.

OM4 Ultra: Dual Windows, Double Performance

OM4 Ultra fibre extends the operating window to 910nm, achieving dual operating windows of 850~870nm and 910nm. This innovative design supports 400Gb/s, 800Gb/s, and 1.6Tb/s single-wavelength and dual-wavelength transmission systems. Utilizing wavelength division multiplexing (WDM) technology, it enables high-speed transmission through fewer fibres, paving the way for potential upgrades to 1.6Tb/s in data centers.

OM5: All-round High Bandwidth, Pioneer in Multi-wavelength Transmission

YOFC MaxBand® OM5 fibre provides comprehensive high bandwidth in the 850~950nm wavelength range. It supports BiDi or SWDM multi-wavelength transmission systems from 40Gb/s to 1.6Tb/s, offering a robust fibre foundation for future SWDM transmission solutions of 1.6Tb/s and above.

Fully Upgraded and Compatible

With the advancement of data center technology, YOFC’s MMFs have evolved from single-window to wide-window, dual-window, and multi-window solutions, offering comprehensive fibre options to customers. These innovative fibre products not only fulfill the demand for higher-speed networks but also ensure backward compatibility, facilitating seamless integration with existing technologies. By providing new fibre optic solutions, YOFC supports the green and low-carbon development of large-scale data centers in the age of AI, driving data centers toward a more efficient and environmentally friendly future.

As a global leader in optical communications, YOFC has been deeply committed to innovation in MMFs for many years. Their MMF products are widely used around the world, earning the trust and praise of numerous customers.

COALITION OF INDEPENDENT INTERNET PROVIDERS ASKS CRTC TO FIX ERRORS IN WHOLESALE FIBRE RATES

Published

By

Coalition of competitive ISPs say current fibre rates make competition impossible and threatens to harm millions of Canadian consumers

CHATHAM, ON, July 23, 2026 /CNW/ — A coalition of independent internet service providers (the Coalition) led by TekSavvy Solutions Inc. (TekSavvy) today applied to the Canadian Radio-Television and Telecommunications Commission (CRTC) to review and vary Telecom Order 2026-77, which set final wholesale rates for fibre internet services. In that decision, the CRTC approved wholesale rates for fibre internet services that are higher than the retail prices charged by the large carriers. This makes competition impossible, as independent providers are forced to either sell at a loss or set prices above the large carriers, leaving millions of Canadian consumers without competitive options for essential internet services.

The application identifies key errors that led the CRTC to approve severely inflated final wholesale rates, which make it economically impossible for independent providers to compete. The Coalition argues that the CRTC’s incorrect rates negate the very purpose of Canada’s wholesale framework, which is to foster competition in retail broadband markets. Specifically, the Coalition asks the CRTC to make three key changes to Telecom Order 2026-77:

Eliminate one cost factor that is inconsistent with the CRTC’s established costing principles, which artificially increased fibre wholesale rates by an estimated 25% to 30% (the Adjustment Factor).Reduce another element of the costing that is inflated above reasonable levels: The Coalition calls on the CRTC to reduce the markup applied to wholesale fibre services from 30% to 15%, reflecting declining costs, operational efficiencies, and the need to support competition.Correct technical errors relating to certain wholesale fibre speed descriptions.

“Canadians were promised greater competition for fibre internet services, but these rates make competition impossible.” said Andy Kaplan-Myrth, TekSavvy’s Vice President of Regulatory and Carrier Affairs. “The CRTC must correct these errors to ensure its wholesale rates promote broadband competition that challenges the market power of monopoly incumbents, lowers prices, and increases consumer choice.”

About the Coalition

The Coalition consists of competitive telecommunications providers and industry associations advocating for fair wholesale access to fibre networks and a competitive broadband marketplace that delivers affordable, high-quality Internet services to Canadians, including: TekSavvy Solutions Inc., BC Broadband Association (“BCBA”), Canada-Wide Internet Service Providers Association (“CanWISP”), Fibernetics Inc., ISP Telecom Inc., National Capital FreeNet Inc., Novus Entertainment Inc. and Purple Cow Internet Inc.

Based in Chatham, Ontario, TekSavvy is Canada’s largest independent telecom service company. TekSavvy has been proudly delivering award-winning services and fighting for consumers’ rights for nearly 30 years. TekSavvy is committed to providing quality competitive choice and closing Canada’s digital divide.

Monk Launches Voice Collections, Bringing AI Phone Calls and Callbacks to Accounts Receivable

Published

Monk’s collections agent, Julia, can now place outbound collection calls and answer inbound AR questions from a dedicated business number, so finance teams can use the channel that collects best without adding headcount.

Multimedia: Watch Voice Collections in action: https://youtu.be/w09PoN1yACE 

NEW YORK, July 23, 2026 /PRNewswire/ — Monk, the AI-native accounts receivable platform, today launched Voice Collections. Its collections agent, Julia, can now place outbound collection calls and answer inbound customer questions about invoices and payments from a dedicated phone number for each organization. The feature brings the phone, long the most effective collections channel and the hardest one to scale, into Monk’s Intelligent Collections.

Roughly $10 trillion sits in unpaid invoices worldwide, and the average invoice now takes 59 days to clear (Allianz). Most accounts receivable runs on email, and most of it waits. More than half of B2B invoices in the United States are overdue at any given time, and 92% of businesses are typically paid after their due date (Chaser, 2026). Phone calls recover overdue invoices two to three times better than email (Dunwise), yet 91% of finance teams still rely on email as their main follow-up channel and only 56% use the phone, because calling every overdue account by hand does not scale and a single human dunning call can cost $12 to $18 (HighRadius).

Voice Collections gives teams that coverage. Julia can call on the accounts a playbook flags for phone follow-up, and answer when a customer calls the same number back to ask about an invoice, a payment, or a bank detail. Businesses that follow up on 100% of overdue invoices are 76% more likely to be paid within a week (Chaser), and a voice agent is what makes full coverage possible.

Monk’s collections agent is already proven on the accounts it handles by email. Across Monk’s first 100 customers, Julia reaches customers with a 24% higher response rate than standard dunning and resolves 88.2% of collections with zero human intervention. Voice extends that reach to the phone.

“For years the assumption was that customers would not talk to an AI on the phone,” said George Kurdin, Founder and CEO of Monk. “The evidence now points the other way. People engage with a good voice agent, and in AR the phone was always the channel that collected best. We built Voice Collections so finance teams can finally use it at the scale email gave them.”

That assumption is worth retiring. In a University of Chicago Booth field study of roughly 70,000 interviews, people interviewed by a voice AI agent were 12% more likely to receive an offer, 18% more likely to start, and 17% more likely to still be there after 30 days, and 80% chose the voice AI over a human when given the choice. The setting was recruiting rather than collections, but the finding travels: given a capable voice agent, people lean in rather than hang up. A call also does something email cannot, which is secure a verbal promise to pay in the moment.

Built for finance, with the phone agents kept with strict guardrails

Voice in finance has to be constrained, and Monk designed Voice Collections around that from the start. The agent is read-only on the phone. It answers questions, confirms details, and routes the next step. It will not rewrite an invoice, change a payment status, or accept a sensitive payment change by voice.

The agent is also reference-based. If a caller asks about an invoice, Julia asks for both the company name and the invoice number before looking anything up, and it will not search broadly from a single detail. Every inbound and outbound call is kept in the collection record alongside the email history, so a callback is part of the same thread the team already sees, and anything that needs judgment escalates to a person.

“Voice in finance has to be careful by design,” said Joe Zhou, Co-Founder and CTO of Monk. “Julia will not browse across accounts or move money over the phone. A caller has to bring the company name and invoice number before it confirms anything, and every call lands in the record. In finance a 1% mistake is still unacceptable, so we built for that first and added the reach second.”

Teams run autonomous collections on Monk

Monk runs collections for finance teams at companies like Unify, Pump, Siro, and Elate, and Voice Collections extends what those teams already do by email onto the phone.

“We chose Monk to help automate our collections, a process previously demanding several hours a week of manual, one-off outreach,” said Will Stewart, Head of Finance and BizOps at Unify. “Today, our Monk agent is always running in the background and I have a single dashboard to manage AR from.”

At Pump, which manages volume across more than 1,500 customers, Monk has helped collect over $10 million in recent months.

Voice AI is now infrastructure

The timing reflects how far voice AI has come. It has moved from demo to infrastructure: Vapi has processed more than 1 billion calls, Bland handles over 3.5 million calls a week, and ElevenLabs raised a $500 million round at an $11 billion valuation in early 2026. Monk builds Voice Collections on that foundation and adds the part finance actually needs, which is the AR context, the controls, and the audit trail.

Voice Collections is available now as an opt-in feature. Monk configures the dedicated number and call behavior with each organization before turning it on in Collections. See it in action: https://youtu.be/w09PoN1yACE.

About Monk

Monk is the AI-native accounts receivable platform that helps finance teams turn revenue into cash. Its agent, Julia, runs collections, cash application, and forecasting as one connected system. Monk resolves 88.2% of collections with zero human intervention, reaches customers with a 24% higher response rate than standard dunning, reduces DSO by more than 40%, automatically matches 80% of incoming payments with a full audit trail, and gives finance teams back roughly 26 hours a month. Teams onboard in under a week and see results in their first month. More than $1.5 billion in receivables is managed on the platform, including for customers like Profound and ElevenLabs. Monk has raised $25 million and is based in New York.
