Single-Fiber Bidirectional Transmission

Transmit and receive signals are carried over one fiber using different optical wavelengths, helping reduce fiber requirements.

2km to 140km Reach

The available configurations cover short-distance 2km links through extended single-mode fiber connections up to 140km.

1310nm/1550nm Wavelength Pair

10km, 20km, 40km, and 60km configurations use complementary 1310nm and 1550nm wavelengths for bidirectional transmission.

1490nm/1550nm Long-Reach Pair

80km, 100km, 120km, and 140km configurations use 1490nm and 1550nm wavelength combinations for extended links.

MMF and SMF Options

The 2km configuration is available for multimode fiber, while longer-distance versions are designed for single-mode fiber.

LC and SC Connector Options

The product specifications provide LC/SC connector choices for integration with different fiber cabling environments.
