Inphi Corporation, a leading provider of high-speed, mixed-signal semiconductor solutions for the communications, data center and computing markets, today announced it will demonstrate a 100GbE Four Level Pulse Amplitude Modulation (PAM4) 56GBaud transmission system up to10km single mode fiber at the Optical Fiber Conference (OFC) 2015, Los Angeles, CA in booth #709.
The demonstration will showcase 100GbE running over a single full duplex fiber pair using Inphi's real-time DSP (Digital Signal Processing) engine, PAM4 electronics with multiple FEC (Forward Error Correction) options and high-speed linear drivers and amplifiers. This demonstration showcases the technology that enables cost effective 100G, with a roadmap to 400G and beyond, for intra-data center and data center to data center connectivity.
Current 100G data center solutions use either four fibers or four wavelengths at 25Gbps per wavelength, thus putting a limit on bandwidth scalability and cost of future solutions. This demonstration shows that transferring the complexity from optics into CMOS electronics with PAM encoding, DSP and FEC technologies, one can attain four times as much bandwidth improvement compared to existing solutions, at a lower cost. Coupled with the availability of high-speed linear driver and amplifier solutions from Inphi, the demonstration showcases a complete electronics platform for single lambda 100G solutions.
"Inphi led the industry by demonstrating a two wavelength 100G solution at OFC last year and is carrying forward its technology leadership with this single wavelength 100G demonstration," said Siddharth Sheth, vice president marketing, Networking Interconnect at Inphi. "The technology advances in this demonstration are invaluable to our data center, carrier and networking customers, who are relying on Inphi to build the next-generation data center and the network that supports it."
"Growth in the data center for 100GbE is on the horizon, but the cost and power consumption of 100G optics continues to be the biggest barrier to more rapid deployment," said Loring Wirbel, senior analyst, The Linley Group. "Single wavelength designs such as PAM4 offer the most cost-efficient solution, so Inphi's demonstration today is an important milestone in accelerating that market growth for 100G."
