"This new service demonstrates how ultra-high bandwidth backhaul, underpinned by flexible spectrum, can transform inter-capital connectivity for critical cloud applications and high-bandwidth tasks," said Nic Tippelt, CTO of Titan Telecoms. "It’s a step forward in enhancing Australia’s digital infrastructure and delivering better services to Australian carriers. We’re excited to be able to deliver 800Gbit/s circuits over infrastructure that traditionally had not supported such high bandwidth."

The new service transports 800Gbit/s services over a 963km flexgrid ROADM network between data centers in Sydney and Melbourne, operating over Lumea’s optical ground wire network. Using the Adtran FSP 3000 TeraFlex ™ CoreChannel ™, the service applies adaptive symbol rate and spectral shaping capabilities, optimizing optical paths and reducing costs. The open technology interoperated with Ciena’s OLS to enable highly adaptive ultra-high-capacity bandwidth. Managed by Adtran’s Mosaic Network Controller with SDN control, the solution improves efficiency through dynamic resource allocation.

"Spectrum services will be key to meeting the escalating demand for high-speed internet and data services. The adaptive baud rate capability of our FSP 3000 TeraFlex ™ technology allows for dynamic adjustment, optimizing spectrum use and extending the reach of optical networks. Designed to inject more capacity into legacy infrastructure, TeraFlex ™ supports 800Gbit/s transport over long distances. It offers excellent client flexibility and efficiency, accommodating a mix of 400Gbit/s, 100Gbit/s and 10Gbit/s client services and multiplexing them to 800Gbit/s to minimize cost per Gbit per kilometer," commented Christoph Glingener, CTO of Adtran. "What’s more, our transmitter’s superior signal-to-noise ratio and receiver’s high noise tolerance help ensure compatibility with existing infrastructure, enabling long transmission distances and facilitating seamless upgrades without major overhauls."

NEW YORK (AP) — Netflix's $72 billion deal to acquire Warner Bros. studio and its film and television operations drew quick reactions Friday.

Film and television industry entities including guilds and the lobbying group for movie theater owners criticized the deal, warning it would harm consumers and cinema owners.

In announcing the deal, Warner Bros. and Netflix executives touted the deal's benefits. Warner Bros. Discovery CEO David Zaslav said the deal “will ensure people everywhere will continue to enjoy the world’s most resonant stories for generations to come,” while Netflix co-CEO Ted Sarandos said it would “give audiences more of what they love.”

Here's a roundup of notable early reactions to the deal:

“Netflix’s stated business model does not support theatrical exhibition. In fact, it is the opposite. Theaters will close, communities will suffer, jobs will be lost.”

“Today’s news that Warner Bros. Discovery has accepted a purchase bid is an alarming escalation of the consolidation that threatens the entire entertainment industry, the democratic public it serves, and the First Amendment itself.” — in a statement

“As we navigate dynamic times of economic and technological change, our industry, together with policymakers, must find a way forward that protects producers’ livelihoods and real theatrical distribution, and that fosters creativity, promotes opportunities for workers and artists, empowers consumers with choices, and upholds freedom of speech. This is the test that the Netflix deal must pass. Our legacy studios are more than content libraries – within their vaults are the character and culture of our nation.” — in a statement.

“Netflix’s $82 billion attempt to buy Warner Bros. would be the largest media takeover in history — and it raises serious red flags for consumers, creators, movie theaters, and local businesses alike. One company should not have full vertical control of the content and the distribution pipeline that delivers it. And combining two of the largest streaming platforms is a textbook horizontal Antitrust problem. Prices, choice, and creative freedom are at stake." — in a statement.

“This deal looks like an anti-monopoly nightmare. A Netflix-Warner Bros. would create one massive media giant with control of close to half of the streaming market — threatening to force Americans into higher subscription prices and fewer choices over what and how they watch, while putting American workers at risk.” — in a statement.

The world’s largest streaming company swallowing one of its biggest competitors is what antitrust laws were designed to prevent. The outcome would eliminate jobs, push down wages, worsen conditions for all entertainment workers, raise prices for consumers, and reduce the volume and diversity of content for all viewers. ... This merger must be blocked.” — in a statement.

“Repeated consolidation in this industry has already cost so many film and television jobs, and any merger should be evaluated on its impacts on competition and employment.” — in a statement. Her district includes Hollywood and the areas where Netflix's headquarters and the Warner Bros. studio are located.

“If I was tasked with doing so, I could not think of a more effective way to reduce competition in Hollywood than selling WBD to Netflix.” — in a post on X.
