MACOM demos linear EML driver for 400G

At OFC 2015, communications semiconductor vendor M/A-COM Technlogy Solutions Inc. (MACOM) is highlighting its MAOM-003115 linear EML driver, which the company says has been used to demonstrate 400-Gbps optical transmission over 2 km of single-mode fiber (SMF) in a 4x100G format.

The company says the demonstration leveraged higher-order modulation formats, but did not identify them.

The surface-mount device can deliver up to 2-Vpp single-ended output. It also offers variable gain control and what MACOM asserts is excellent linearity over the operating range.

"We are proud to offer the industry's first linear EML driver for 400G applications," said Ray Moroney, product manager at MACOM.
