Macom Announces 25G Lasers for 5G Front-haul

Etched Facet Technology (EFT) is poised to enable 25G laser manufacturing at commercial scale

Macom has announced a new portfolio of 25G distributed feedback (DFB) lasers designed for use in next-generation 5G LTE wireless front-haul infrastructure.

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 85degC temperature range over transmission distances from 2 to 10km. The new 25G lasers will meet stringent operating requirements while helping to expand wireless infrastructure bandwidth for high-speed 5G connectivity.
The industrial temperature-grade 25G laser portfolio uses Macom's proprietary EFT, which at commercial scale manufacturing levels, could enable breakthrough cost efficiencies and product uniformity. Macom 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.
"Macom's new 5G LTE-optimized 25G laser family builds on our comprehensive portfolio of 5G enabling technologies, and again demonstrates the value of EFT for achieving production efficiency that scales to meet industry supply and cost structure needs," said Fang Wang, VP and business line manager, Lightwave, Macom. "For customers transitioning from 10G to 25G wireless fronthaul infrastructure, Macom can provide the 25G lasers, complementary components and application expertise to help accelerate deployment time and reduce costs."
Macom's industrial temperature-grade 25G lasers are sampling to customers today, with production availability planned for 2019. It will be showing the new range at the European Conference on Optical Communication (ECOC), in Rome, Italy, September 24th "“ 26th.
