QSFP-100G-LRL4 Arista 100GBASE-LRL4 1310nm Duplex SMF QSFP28 Transceiver

The Arista QSFP-100G-LRL4 transceiver is primarily utilized in environments demanding reliable, high-speed connectivity over extended distances. It is ideal for large-scale data centers, enterprise campuses, and service provider networks where long-reach single-mode fiber links are necessary to bridge infrastructure across dispersed racks or buildings.

How It's Used:

• Connecting core switches to aggregation layers in data centers with rack separation beyond 5km.
• Linking distributed storage clusters in enterprise IT deployments requiring 100Gbps throughput over single-mode fiber.
• Extending network backbone connectivity between geographically separated campus buildings.
• Supporting high-bandwidth virtualized environments where low latency and long-distance links improve performance.
• Enabling service provider edge-to-core interconnects where fiber runs exceed typical short-reach distances.

By facilitating stable 100G links over distances up to 10 kilometers, this transceiver supports scalable network architectures and reduces the need for intermediate switching equipment. It enhances operational efficiency by enabling direct high-speed fiber connections across large physical footprints without compromising signal integrity.
