Macom to Demo 200G and 400G Optical Modules

Fully analogue chipset for cloud data centres delivers low latency with power consumption under 22 milliwatts per gigabit

Macom has announced live demonstrations of the industry's first complete chipset solution for 200G and 400G CWDM optical module providers servicing cloud data centre applications. The demos will be at the China International Optoelectronic Exposition CIOE (Shenzhen, September 5th"“ 8th) and at the European Conference on Optoelectronic Communication ECOC 2018 (Rome, September 24th"“ 26th)

This solution enables 200G modules at under 4.5W and 400G modules at under 9W total power consumption, thus delivering power efficiency with a fully analogue architecture that ensures extremely low latency and is poised to provide a lower cost option compared to DSP-based offerings.

Macom's full transmit and receive solution operates at up to 53 Gbps PAM-4 data rates per lane and is optimised for use in 200G QSFP56 and 400G QSFP-DD and OSFP module applications. For 200G demonstration, the solution is comprised of the MAOM-38051 four-channel transmit CDR and modulator driver and MAOT-025402 TOSA with embedded MAOP-L284CN CWDM L-PIC (silicon photonic integrated circuit with integrated CW lasers) transmitter, and on the receive side features the MAOR-053401 ROSA with embedded demultiplexer, BSP56B photodetectors MATA-03819 quad TIA and the MASC-38040 four-channel receive CDR. The combined, high-performance Macom solution enables a low bit error rate (BER) and better than 1E-8 pre-forward error correction (Pre-FEC).

"Macom is committed to leading the evolution of data centre interconnects from 100G to 200G and 400G, as evidenced by our unique ability to deliver a complete 200G chipset and TOSA/ROSA subassembly solution with market leading performance and power efficiency," said Gary Shah VP, High-Performance Analog Business Line, Macom. "With this solution, optical module providers are expected to benefit from seamless component interoperability and a unified support team, reducing design complexity and costs while accelerating their time to market."

All of the Macom products highlighted in the forthcoming 200G live demonstrations are sampling to customers, with production availability targeted for early 2019. Customers can select from component-level solutions or a TOSA/ROSA subassembly-level solution.
