100GBASE-LR4 QSFP28 1310nm 10km DOM LC SMF Optical Transceiver Module - Compatible Arista

This Telco Parts transceiver is a 100 Gbps QSFP28 optical module for 100GBASE-LR4 Ethernet connections over single-mode fibre. Operating in the 1310 nm wavelength band with an LC duplex interface, it supports distances of up to 10 km. It is suitable for connections between compatible switches and routers in data centres, enterprise backbone networks and telecom infrastructure.

The module uses two fibre strands, one for transmitting and one for receiving. The achievable distance depends on fibre characteristics and total optical link loss, including connectors and splices.

Digital Optical Monitoring (DOM/DDM) provides diagnostic information through compatible network equipment for monitoring and troubleshooting. The hot-swappable module operates within a temperature range of 0 to 70 °C.

Available with Arista, Cisco, Dell or Juniper compatibility options. Select the appropriate option and verify support for your device model and software version before ordering. Use an optically compatible 100GBASE-LR4 transceiver at the opposite end.
