Nokia transceiver bakes years of demos into superfast optical chip
Wednesday, 07 March 2018 16:02

Two years after it first demonstrated its highest-capacity modulation scheme, Nokia has announced its release as a product.

The company will show off its PSE-3 (photonic service engine) in San Diego next week, at the OFC Conference.

Nokia claimed even over long-haul submarine cable systems, 200 Gbps (per wavelength) can be deployed nearly everywhere, regional-scale links can run at 400 Gbps, and data centre interconnects can support 600 Gbps per wavelength.

Nokia's announcement says the PSE-3 can increase network capacity by “65 percent over currently deployed networks” at 60 percent lower power, and can be applied to carrier networks from

nbn™ gives ISDN, Frame Relay and Ethernet Lite a stay of execution
Wednesday, 07 March 2018 14:32

Horror stories about poor installation experiences for Australia's National Broadband Network (NBN) are everywhere, which might be making businesses reluctant to give up old but reliable services. To get those customers over the line, nbn™, the company building and operating the NBN, has announced it will let business customers keep their ISDN services in parallel with an NBN connection until they're ready to migrate.

While Telstra only publishes “services in operation” (SIO) data for ISDN, that service alone shows remarkable persistence with nearly a million “basic access line equivalents” in service. There's not, however, a 1:1 relationship between those services

April Fool: FCC finally bothers with Puerto Rico as chairman visits
Wednesday, 07 March 2018 08:59

The Federal Communications Commission (FCC) has finally decided to address the months-long lack of telecoms service in Puerto Rico, one day before its chair visits the storm-ravaged island.

It has been over five months since the US territory was struck by Hurricane Maria and yet, according to the FCC's own figures, 4.3 per cent of the island remains without mobile phone service.

On Tuesday, the day before FCC chair Ajit Pai is due to visit the island, the federal regulator suddenly announced – or, more accurately, "proposed" - $750m in resources to restore and expand communications networks in Puerto Rico.

123 Reg suffers deja vu: Websites restored from August 2017 backups amid storage meltdown
Tuesday, 06 March 2018 22:27

The UK's self-proclaimed number one website provider, 123 Reg, is having yet another very bad day, although arguably not as bad as those of its long-suffering customers.

We're told 123 Reg has hit upon the ultimate method to protect users' website files from hackers by, er, losing them. The hosting biz suffered a storage cockup – likely, failed disks – forcing it to restore some unlucky punters' websites from backups... that date back to August 2017.

Other users are reporting their 123 Reg-hosted websites have been taken offline with no indication from the Brit biz as to the nature of

Cisco buffs Tetration for application protection
Tuesday, 06 March 2018 14:58

Cisco has updated its Tetration network monitoring software to tackle application security and multi-vendor policy enforcement.

Tetration's earlier iterations focussed on giving users visibility of network operations and performance in the data centre, while Cisco's Stealthwatch did the same for campus networks.

The company thinks those tools have network security nailed, and so has turned its attention to securing applications by letting Tetration inspect processes and set policies across the network.

The new version of Tetration can therefore peer into workloads and check that processes are only sending traffic to destinations approved by policy. The software will also examine all

Marvell cooks up 400* Gbps Ethernet chips
Tuesday, 06 March 2018 13:55

Marvell Semiconductor is off and running with 802.3cd-compliant chips, and reckons it's the first sand-baker to ship to the standard.

The IEEE's 802.3cd standard defines the physical ports for current and future high-speed Ethernet interfaces – the 50 Gbps, 200 Gbps and 400 Gbps rates expected over time to replace 25 Gbps and 100 Gbps.

Marvell's Alaska C 88X7120 transceivers, sampling now, support 16 50 Gbps ports, four 200 Gbps ports, and two 400 Gbps ports, using PAM4 signalling. They're aimed at top-of-rack switches with interfaces from 25 Gbps to 100 Gbps, and 200/400 Gbps Ethernet line cards.

PAM4 is
