The Arista Networks QSFP-40G-PLR4 Compatible QSFP+ Optical Transceiver Module is designed for use in 40GBASE Ethernet throughput up to 10km over single mode fiber (SMF) using a wavelength of 1310nm via a MTP/MPO connector. It provides high-density and low-power 40GBASE Ethernet solution for data centers, high-performance computing networks, enterprise core and distribution layer applications. It is fully compliant with the QSFP+ MSA and IEEE 802.3ae 10GBASE-LR/LW and OTN data rates OTU2, OTU1e, and OTU2e per the ITU. standard.
Note: If this transceiver needs to be used to break out one 40G signal into 4x 10G signals, the interface of the device is required to support the breakout feature.
