MACOM reveals smart solutions to support 5G at ECOC 2018

MACOM showcased its first complete chipset solution for 200G and 400G CWDM optical module providers servicing cloud data centre applications, at this year’s ECOC. It is designed to enable 200G modules at under 4.5W, and 400G modules at under 9W total power consumption, with a fully analogue architecture to ensure low latency and lower cost.

The full transmit and receive solution operates at up to 53Gb/s 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. On the receive side is 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).

The products highlighted in the 200G live demonstrations are already sampling to customers, and production availability is predicted for early 2019.
