Comprehensive Solutions

Lumulus offers a comprehensive portfolio of optical transceivers covering data rates from 155 Mb/s to 1.6 Tb/s, supporting a broad range of enterprise, telecom, AI, and data center applications. Our solutions are available with EEPROM customization, private labeling, and custom product labels to meet OEM and project-specific requirements, combining performance, compatibility, and flexible branding.

Loopback & Converters include essential tools for network testing, validation, and media conversion. Loopback modules enable fast verification of optical interfaces during manufacturing, deployment, and troubleshooting, while media converters provide reliable signal conversion between different transmission media and network interfaces, supporting seamless integration across a wide range of Ethernet and fiber optic applications.

From 30m to 120km

Every module is tested for signal integrity, temperature stability, and host compatibility before it ships.
