Description

This Arista QSFP-100G-LR4 is a 100GBASE-LR4 QSFP28 optical transceiver that carries 100 Gigabit Ethernet up to 10km over duplex single-mode fibre with LC connectors. It follows the IEEE 802.3 100GBASE-LR4 standard and suits 100G data centre interconnect, campus backbone and metro or inter-building links.

The module uses four 25G NRZ lanes in the 1295-1309nm LAN-WDM band over G.652 single-mode fibre. Transmit power is -4.3 to +4.5 dBm per lane and receive power is -10.6 to +4.5 dBm per lane. It draws a maximum of 4.5W from the host switch QSFP port, so no external power is needed. The 10km, duplex SMF, LC (LR4) reach separates it from shorter-reach 100G optics.

It works in Arista switches with QSFP100 (QSFP28) ports, with minimum EOS version and platform support listed in the Arista Transceiver Guide. It interoperates with the QSFP-100G-LRL4 over links up to 2km, and with the QDD-200G-2LR4 and OSFP-200G-2LR4 modules.
