Description
This AddOn Arista Networks® QSFP-100G-ERL4 compatible QSFP28 transceiver delivers reliable 100GBase-ER4L Ethernet connectivity over single-mode fiber (SMF) at distances up to 40 km with forward error correction (FEC). Operating across wavelengths from 1295 nm to 1309 nm, it connects via a duplex LC connector and features Digital Optical Monitoring (DOM) for real-time performance diagnostics.
Each unit is programmed, uniquely serialized, and application-tested to ensure seamless interoperability and identical performance to the OEM version. The transceiver is hot-swappable, TAA-compliant, and designed for enterprise, access, and data center networks. With robust ESD protection, low EMI metal housing, and RoHS compliance, this module ensures consistent, high-performance optical networking and long-term reliability.
