400GBASE-FR4 transceiver, up to 2km over duplex SMF. 2 x 200GBASE-FR4 transceiver, up to 2km over two pairs of duplex SMF.
2 x 200G-FR4 links, and has a reach of 2km using single-mode fiber. Each of the 200G FR4 links has 4 optical channels, multiplexed onto one fiber pair (1 Tx and 1 Rx per 200G link). A 400G-2FR4 module has 2 of these links, resulting in a total of two pairs of single mode fiber (or 4 fibers total), and a total of 8 optical channels. Each optical channel operates at 50Gb/s. The 2FR4 module uses a dual CS connector to connect to 2 fiber pairs.
