Enabling Optical Connectivity Everywhere

Bandwidth-hungry multimedia and video, the Internet of Things, cloud services, big data – the list of things that gobble bandwidth at alarming rates is growing – as is the need for faster and faster ways to move all of this data. For demanding applications such as data center interconnects, high-performance A/V interconnects and many more – fiber optics is the answer. Cosemi’s business model and technical proficiency allow us to provide the most technically capable optical devices, sub-assemblies, photodiode arrays and active optical cables available. Our high-quality, high-volume, high-performance products are connecting your industry.


"Connecting" Your Industry

  • Data Center Interconnect

    The use of high-speed optical interconnects is more popular than ever before thanks to cloud computing and 100Gb/s becoming the standard. Cosemi’s extensive (and ever-growing) portfolio of photodiode arrays support the high-bandwidth needs of the data center.

  • Telecom

    The proliferation of smart phones and Internet of Things-connected devices have created massive data growth – and fiber optic links provide the efficient, powerful computing needed to process all of this data. Cosemi’s photodiodes and optical subassemblies (OSAs) bring low costs and the highest possible speed and bandwidths available.

  • GPON

    The Fiber to the Home (FTTH) market needs field reliable, cost-effective, GPON and 10GPON solutions - supplied in massive quantities. Cosemi provides the photodiodes, receive and transmit optical sub-assemblies (ROSAs/TOSAs), and bi-directional optical sub-assemblies (BOSAs) required, reliably, and on-time.

  • High Performance A/V Interconnect

    From 4K to 8K Ultra HD, video standards are advancing. Traditional copper connections can't handle the data and speed now involved in interconnecting players, projectors, cameras, and various display monitors and televisions. Cosemi’s active optical cable technology brings affordable, high-performance interconnects for all of the latest video standards.

  • Non-Hermetic Environments

    To protect sensitive high-speed optical components from exposure to humidity and other environmental stressors, expensive hermetic packaging has typically been required. Cosemi is leading the industry by coating photodiodes to make them innately hermetic – no additional packaging required. This trademarked process is known as Die Level Hermeticity Technology (DLH) Technology™.
