Ribbon adds TM400_2 400G ZR+ line card to Apollo optical transport system
Ribbon Communications Inc. (NASDAQ: RBBN) has unveiled the TM400_2 line card, which supports 400G ZR+ optics. The line card is designed for use in the company’s Apollo metro and long-haul optical transport system line.
The TM400_2 accepts 400 ZR+ capable CFP2-DCO pluggable modules optimized to support colorless directionless, and contentionless ROADM network requirements. They operate in either independent wavelength or dual carrier modes. In the former mode, the two 400G wavelengths provide 800G of capacity at a lower price point than embedded 800G technology, particularly in metro applications, Ribbon asserts. In dual-carrier mode, the TM400_2 combines a pair of 200G wavelengths to create a 400G channel for long-haul applications.
“Operators now have the option to build their optical transport systems with multiple 400G lanes, increasing cost efficiencies and network flexibility over embedded optical solutions,” said Jimmy Yu, vice president, Dell’Oro Group. “This innovation is well-timed to prepare for the rise of 400GbE transport as the next dominant load being carried over optical networks.”
“With traffic loads increasing, our customers are looking for a revolutionary transport solution that meets today’s and tomorrow’s needs,” said Sam Bucci, executive vice president and general manager of Ribbon’s IP Optical Networks Business Unit. “We’re proud to be the first to market with this flexible, cost-effective solution.”
