Infinera announces Layer 1 OTN encryption on mTera Universal Switching Platform

Infinera says the mTera Universal Switching Platform it acquired along with the rest of Coriant now offers Layer 1 Optical Transport Network (OTN) data encryption capabilities. The new feature offers better service differentiation than using bulk traffic encryption, the company says.

Infinera says the mTera Universal Switching Platform it acquired along with the rest of Coriant (see “Infinera closes Coriant acquisition”) now offers Layer 1 Optical Transport Network (OTN) data encryption capabilities. The new feature offers better service differentiation than using bulk traffic encryption, the company says.

The Layer 1 encryption option is software enabled and can be applied at wire speed at rates up to 100 Gbps. It also accommodates 10 Gbps and subrate leased line services with Ethernet, OTN, SONET/SDH, as well as other client interfaces, Infinera says. Unlike approaches that bulk encrypt all the data going through a transponder, the mTera’s Layer 1 OTN data encryption approach enables network operators to selectively encrypt individual or multiple services.

“Securing customer traffic has never been more important to communications service providers and internet content providers as their networks face increased attacks,” said Uwe Fischer, senior vice president of the System Solutions Business Group at Infinera, who joined the company from Coriant. “Best-in-class technology like Layer 1 OTN data encryption on the mTera platform helps network operators create differentiation and expand their breadth of services, all while protecting customer data and privacy.”

As its name implies, the mTera is designed to support the switching and transport of a variety of packet traffic, including OTN, Multiprotocol Label Switching-Transport Profile (MPLS-TP), and Carrier Ethernet (see “Coriant offers mTera Universal Transport Platform for packet optical transport”). It is the second Coriant platform for which Infinera has announced upgrades since the acquisition closed. The first was the Groove G30 Disaggregated Network Platform (see “Infinera adds new features to Groove G30 Network Disaggregation Platform”).
