HCH offers 155M and 1G BIDI SFP transceivers designed for bidirectional transmission over a single optical fiber.

Using WDM technology, BIDI modules transmit and receive signals on different wavelengths, reducing fiber usage and deployment costs. These modules are widely used in FTTx access networks, telecom infrastructure, enterprise connectivity, and metropolitan optical networks.

Multiple wavelength combinations and transmission distances are available to support different network architectures.
