MACOM Unveils 25G DFB Lasers for 5G LTE Wireless Fronthaul

Posted Sep 07, 2018 by MACOM

MACOM has introduced a new portfolio of 25G distributed feedback (DFB) lasers designed for use in next-generation 5G LTE wireless fronthaul infrastructure. Building on MACOM’s legacy of industry leadership in 4G LTE connectivity solutions, the new laser portfolio is expected to help wireless operators deploy 25G optical links at commercial scale and cost structures on the path to 5G.

Available in bare die chip format (1xxD-25I-LCT11-50x) and TO-packaging (1xxD-25I-LT5xC-50x), MACOM’s new 25G DFB lasers are designed for operation in the -40 to 85oC temperature range over transmission distances from 2 to 10 kilometers. The new 25G lasers will meet stringent operating requirements while helping to expand wireless infrastructure bandwidth for high-speed 5G connectivity.

The new industrial temperature-grade 25G laser portfolio leverages MACOM’s proprietary EFT, which at commercial scale manufacturing levels, could enable breakthrough cost efficiencies and product uniformity. The company believes that this high-volume production capability distinguishes us as a leading provider of 25G lasers across a host of Cloud Data Center and wireless infrastructure applications.

The lasers are sampling to customers currently, with production availability planned for 2019. MACOM is showcasing its new portfolio at the China International Optoelectronic Exposition (CIOE) 2018 in Shenzhen, China from September 5th – 8th, and at the European Conference on Optical Communication (ECOC) 2018 in Rome, Italy from September 24th – 26th.
