Description
This AddOn Arista Networks® QSFP-100G-ERL4-AR-4WDM-40-I compatible QSFP28 transceiver delivers 100GBase-4WDM-40 throughput up to 40km over single-mode fiber (SMF) using LAN-WDM wavelengths from 1295nm to 1309nm via an LC connector. Designed for high-performance data center, enterprise, and telecom applications, this transceiver features four 25Gbps cooled DFB-based lasers and supports FEC on the host side. It is hot-swappable, MSA-compliant, and equipped with an I2C interface for real-time Digital Optical Monitoring (DOM). With a robust operating temperature range from -40°C to 85°C and a power consumption under 5W, it ensures reliable performance in demanding environments. Each unit is programmed, uniquely serialized, and thoroughly tested for guaranteed compatibility and seamless integration with Arista Networks® systems. TAA compliant and backed by a limited lifetime warranty, this module delivers enterprise-grade reliability and performance.
