NVIDIA 100GbE 100GBASE-LR4 QSFP28 LC-LC Optical Transceiver

The NVIDIA 100GbE 100GBASE-LR4 QSFP28 optical transceiver is a pluggable module for optical Ethernet links in compatible networking equipment. It supports data rates up to 100 Gbit/s, making it suitable for 100GbE connections in data centres and other high-capacity network environments. Its rated reach is up to 10 km over single-mode fibre. This range supports links between network equipment that are beyond the reach of short-distance optical modules. The transceiver is intended for installations that require a standards-based, long-reach 100GbE optical connection.

The QSFP28 form factor identifies the module type and should be checked against the available transceiver ports on the intended equipment. Fibre connections use duplex LC interfaces, with separate paths for transmit and receive. The 100GBASE-LR4 designation specifies the optical link standard supported by the module. Digital diagnostic monitoring is available through an I²C management interface, providing access to module operating information. Compatibility should be confirmed with the network equipment before installation, as support depends on the specific device.
