    \n
  1. SR8<\/strong>: SR is an abbreviation of Short Range, it refers to transmitting over multimode fiber up to 100m, while 8 means 8x optical channel pairs (8x Tx and 8x Rx), as for 400G optical module, each optical channel transmits over 50Gb\/s and with MPO-16\/MPO-24 receptacle. The SR8 module can be configured for 400G-SR8, 2x 200G-SR4, and (operating at 1\/2 rate) 2x 100G-SR4.<\/li>\n
  2. DR4\/XDR4 (FR)\/XXDR4 (LR)<\/strong>: They respectively refer to transmitting distances 500m\/2km\/10km via single mode fiber. 4x means 8x optical channel pairs (4x Tx and 4x Rx), 400G QSFP-DD transceivers transmitting 400G over 4 optical lanes and each lane for 100G, and normally using MPO-12 single mode receptacle. Besides the MPO-12 receptacle, some vendors are developing new models by using VSFF connectors, thus it can be realized by using 4x SN connectors, etc.<\/li>\n
  3. FR4\/LR4\/ER4<\/strong>: They respectively refer to transmitting distance of 2km\/10km\/40km via single mode fiber. 4x means 8x optical channel pairs (4x Tx and 4x Rx), 400G QSFP-DD FR4\/LR4\/ER4 transceivers transmitting 400G over 4 optical lanes and each lane for 100G, however, the optical channels are multiplexed onto a single fiber, thus 400G QDD FR4\/LR4\/ER4 transceivers using duplex LC optical receptacle.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
