Description
This Arista Networks® QSFP-100G-ERL4-AR-4WDM-40-I compatible QSFP28 transceiver provides high-performance 100GBase-4WDM-40 connectivity with a reach of up to 40km over single-mode fiber (SMF) using wavelengths from 1295nm to 1309nm via an LC connector. Designed for demanding environments, it operates reliably in rugged conditions with a wide temperature range of -40°C to 85°C. The module is hot-swappable and built to meet or exceed OEM specifications, ensuring seamless interoperability and optimal network performance. Each unit is uniquely serialized, programmed, and tested for data traffic and application compatibility, and it supports Digital Optical Monitoring (DOM) for real-time performance monitoring. Fully compliant with MSA standards and TAA regulations, this transceiver is an ideal solution for data centers, optical networks, and enterprise backbone infrastructure requiring robust and scalable 100GbE connectivity.
