Applied Optoelectronics launches 100G optical engine

Applied Optoelectronics Inc (AOI) of Sugar Land, near Houston, TX, USA, a manufacturer of fiber-optic access network products (including components, modules and equipment) has announced a new optical engine for use in 100Gbps transceivers for data-center applications.

The new optical engine combines four 25Gbps laser diodes (manufactured in AOI's MBE fab in Texas), a receiver array, an optical fiber array and the associated integrated laser-diode drive electronics and trans-impedance amplifiers into a single optical subassembly that is the major building block required for assembly of a 100Gbps parallel single-mode (PSM4) transceiver. The light engine also features a high-reliability non-hermetic design for cost efficiency as well as a proprietary housing design for improved heat dissipation. The transceivers are designed to address the growing market demand for 100G optics and are expected to be used in next-generation data-center interconnects to facilitate higher data throughput between servers and switches.

"We expect this device to be a critical building block for QSFP-28 transceivers using the PSM4 optical interface," says Dr Fred Chang, AOI's senior VP of the Optical Component business unit.

Both MSA-compatible and fiber-pigtail versions of the light engines are available now in sample quantities, with volume production expected this year.
