100G Over Single Fiber, Simplified

Upgrading from 10G to 100G no longer requires complex fiber builds. Our QSFP28 Bidirectional (Bidi) transceivers delivers high-speed 100G connectivity over a single strand of fiber, with reach options up to 70km and support for both standard and industrial temperature environments.

Designed for service providers, data center operators, and access networks, our Bidi solutions enable you to scale bandwidth, reduce deployment costs, and extend reach—without laying new fiber.
