Inphi announces production availability for first 64GBaud linear coherent TIA

Inphi Corp of Santa Clara, CA, USA (a provider of high-speed mixed-signal ICs for communications, computing and data-center markets) has announced the immediate production availability of its IN6450TA, which is claimed to be the first 64GBaud dual-channel linear TIA/VGA amplifier. The IN6450TA supports data rates of 400G to 600G on a single wavelength for long-haul, metro and data-center interconnect (DCI) applications. The IN6450TA is being showcased in booth #3601 the Optical Fiber Communication conference & exhibition (OFC 2017) in Los Angeles (21-23 March).

With the ever-growing demand for more bandwidth, service providers and data-center operators are looking into more efficient technologies such as flexible coherent DWDM transmission capable of changing transmission capacity and reach on demand, depending on traffic and capacity needs of the network. This is achieved by utilizing components capable of supporting multiple modulation formats and baud rates. The IN6450TA is designed to work with multiple modulation formats supporting different data rates up to 600G on a single wavelength.

“Inphi continues to demonstrate its commitment to delivering TIAs designed for the highest performance applications,” comments Ferris Lipscomb, VP of marketing at NeoPhotonics Corp of San Jose, CA, USA. “We were pleased to work closely with Inphi on the design of the IN6450TA and to incorporate it into our state-of-the-art 64GBaud Micro-ICR for high-density line cards and pluggable transceivers,” he adds.

“100G+ speeds are now the key engine for supporting annual capacity growth in the 30%+ per year range,” notes Heidi Adams, senior research director at market analyst firm IHS Markit. “Technology that can support the delivery of efficient and flexible 400/600G data rates for long haul, metro and DCIs will be key to staying ahead of bandwidth demand in the data networks of tomorrow.”
