Optical component developer Applied Optoelectronics, Inc. (NASDAQ:AAOI) has unveiled an optical engine for 100-Gbps optical transceivers aimed at data center networks.
The optical subassembly comprises four laser diodes, a receiver array, an optical fiber array, and the associated drive electronics. The optical engine should prove useful in 100-Gbps parallel single-mode (PSM4) QSFP28 optical module designs, the company believes.
Applied Optoelectronics cites the following features as important:
- the 25-Gbps laser diodes are manufactured in the company's MBE fab in Texas
- a high-reliability non-hermetic design enables cost efficiency
- integrated laser diode drivers and transimpedance amplifiers (TIAs) simplify design
- a proprietary housing design improves heat dissipation
- both MSA-compatible and fiber-pigtail versions are available.
The light engines are available now in sample quantities with volume production expected this year.
