Product Description
The Arista XVR-10081-21 is a cutting-edge QSFP28 transceiver engineered to deliver 100 Gigabit Ethernet connectivity over single-mode fiber. This module is compliant with the 100GBase-LR4 standard, which employs coarse wavelength division multiplexing (CWDM) to transmit data over four separate optical lanes, each operating at 25Gb/s. This approach allows for high bandwidth density and efficient use of fiber infrastructure. The transceiver is designed for extended reach applications, supporting distances of up to 10 kilometers on standard single-mode fiber. It typically uses an LC connector, often a duplex or quad LC, to interface with the fiber optic cabling. The use of SMF is crucial for maintaining signal integrity over these longer distances, minimizing signal degradation and ensuring reliable data transmission. Ideal for data center interconnects, high-performance computing clusters, and enterprise backbone networks, the XVR-10081-21 enables the aggregation of multiple 25Gb/s links into a single 100Gb/s connection. Its hot-pluggable nature simplifies deployment and maintenance, allowing network administrators to install or replace modules without powering down the host equipment.
