Description
The AddOn Arista Networks® QSFP-100GB-129780-20-E-AR-AO is a high-performance, TAA-compliant 100GBase-OWDM QSFP28 optical transceiver designed for high-speed data center, enterprise, and carrier network applications. Operating at a wavelength of 1297.80nm, it supports data rates up to 106.25Gbps (PAM4) and delivers reliable transmission up to 20km over single-mode fiber (SMF) through duplex LC connectors.
Built with a high-sensitivity APD receiver and supporting OWDM with 8 wavelengths, this module ensures robust signal integrity and performance. It is fully compliant with QSFP28 MSA, IEEE 802.3bs, and 100G Lambda MSA standards, and includes Digital Optical Monitoring (DOM) for real-time diagnostics. Each transceiver is hot-swappable, uniquely serialized, and rigorously tested for guaranteed compatibility and seamless interoperability with Arista Networks® equipment.
