Description

Two-channel 400G OSFP transceiver implementing 400GBASE-2FR4 for 2km reach on single-mode fiber. Uses two independent 200G FR4 optical groups presented via dual LC duplex connectors, enabling flexible connectivity and migration paths. Suitable for scenarios needing dual 200G or aggregated 400G over duplex cabling. Optical interop requires matching 2FR4/FR4 endpoints per channel.

Features

- Two independent 200G FR4 channels via dual LC duplex
- Up to 2 km reach on OS2 single-mode fiber
- Flexible deployment: dual 200G or aggregated 400G
