MACOM launches quad-channel surface-mount modulator drivers for 100, 200 and 400G coherent long-haul

M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog, RF, microwave and millimeter-wave applications) has announced the newest additions to its portfolio of modulator drivers for line-side applications at 100G and beyond.

The MAOM-003406 and MAOM-003408 are quad-channel 32Gbps modulator drivers in small-form-factor surface-mount packages. The parts are designed to operate with the latest surface-mount lithium niobate optical modulators, enabling the next generation of OIF transponders in the 4”x5” form factor. The new products expand on MACOM’s existing portfolio of single- and dual-channel surface-mount drivers and quad-channel GPPO modules, which are shipping in volume in first-generation 100G systems.

The MAOM-003406 is a limiting driver that can deliver up to 7.2Vpp output voltage. The MAOM-003408 is a linear driver with up to 6Vpp linear output voltage. Both have differential inputs to minimize cross-talk and to optimize the interface to the digital-to-analog convertor (DAC) on linear systems. The single-ended outputs are designed to interface directly to the modulator inputs with minimal parasitics. The drivers are each integrated in 13mm x 19mm surface-mount packages and are pin compatible to enable a common board design across system platforms.

“MACOM can now claim the broadest portfolio of modulator drivers for coherent applications, with solutions for all data rates, modulator types and module form factors,” claims Ray Moroney, product line manager for Optoelectronics.

Samples of the MAOM-003406 and MAOM-003408 are available now and are being demonstrated in booth 2203 at the Optical Fiber Communication conference & exposition (OFC 2014) in San Francisco (11-13 March).
