Padtec introduces compact DWDM supporting 400ZR modules

Padtec introduced a 1RU DWDM platform with dual transponders supporting up to 400 Gbps per optical channel, or 800 Gbps in total – in short and medium distances. The platform offers SDN management and low energy consumption.

“One of the product’s technical innovations is the use of QSFP-DD pluggable modules in the OpenZR+ standard, a trend that reduces the cost per transmitted bit, with high energy efficiency, in coherent optical systems. In addition, it has functionalities that adapt the rates to the operating conditions of each network, which allows providers to start with 100 Gb/s channels and gradually expand capacity, reaching 400 Gb/s channels”, highlights Roberto Nakamura, Padtec’s Chief Technology Officer.

Carlos Raimar, Padtec’s CEO and Investor Relations Officer, points out that the development of the new solution is in line with the company’s commitment to constantly invest in the evolution of its product line in line with market demands. “With a more affordable cost, the advantages of DWDM are within reach of regional network operators who need to meet their customers’ ever-increasing demands for bandwidth and new services”, says the executive. “This launch reinforces our commitment to providing solutions that, in addition to being innovative and using state-of-the-art technology, support the evolution of our customers’ businesses”, he concludes.

UNH-IOL and Microchip expand 1000BASE-T1 automotive compliance testing

The University of New Hampshire InterOperability Laboratory (UNH-IOL) have expanded testing for the 1000BASE-T1 PCS and PHY Control market to help further compliance for the automotive industry. UNH-IOL has partnered with Microchip Technology, who created a development test platform that is compatible with OPEN Alliance Test Plans for 1000BASE-T1 conformance testing.

“To advance Ethernet in-vehicle networking, multi-vendor, standards-compliant devices are a necessity,” said Charles Forni, Vice President of Microchip’s USB and Networking business unit. “Microchip is pleased to partner with UNH-IOL to enable the test capability to deliver interoperable devices, providing the market with added choice and flexibility for Single Pair Ethernet.”

The UNH-IOL has been a key player in the automotive industry supporting the adoption and standardization of in-vehicle Ethernet technologies for many years, contributing to various standards bodies and industry alliances, including IEEE®, Avnu Alliance and OPEN Alliance. The new capability enables testing based on the OPEN Alliance TC12 test plans and clearer definitions of the tests inside the OPEN Alliance TC12 test plans authored by UNH-IOL staff.

“IEEE conformance validation of Single Pair Ethernet is essential for automotive OEMs and semiconductor vendors alike,” said Bob Noseworthy, Principal Engineer at UNH-IOL. “Microchip’s support in enabling this capability is greatly appreciated.”

Calix posts Q4 revenue of $244.5m, up 39% yoy

Calix reported Q4 2022 revenue of $244.5m (GAAP),  increasing 39% compared with the same quarter a year ago. Driven by this demand, systems revenue in the fourth quarter of 2022 increased 40% compared with the same quarter a year ago. Compared with the prior quarter, services revenue was up 9%.

U.S. revenue was 91% of total revenue in the fourth quarter of 2022 and increased 46% compared with the year ago quarter and increased 3% sequentially. This annual increase is primarily due to continued sales and marketing investments in the U.S. to address the significant opportunity ahead. International revenue was 9% of total revenue in the fourth quarter and declined 6% compared with the year ago quarter primarily due to lower shipments to Europe and Africa partially offset by shipments to Canada.

Revenue from small customers was 78% of total revenue in the fourth quarter of 2022, down from 84% in the year ago period, but increased 29% in absolute dollars.

GAAP gross margin decreased 60 basis points year-over-year to 51.1%.
