Description
The AddOn Arista Networks® SFP-25G-ER-AR Compatible TAA 25GBase-ER SFP28 Transceiver delivers high-performance 25-Gigabit Ethernet connectivity over single-mode fiber (SMF) for distances up to 40 km using a 1310 nm wavelength via an LC duplex connector. Designed for demanding access, metro, and enterprise networks, this hot-pluggable module ensures seamless deployment and 100% compatibility with Arista Networks® equipment.
Built to the SFF-8432 and SFF-8472 MSA standards, the transceiver features digital optical monitoring (DOM) for real-time performance data, robust ESD protection, and industrial-temperature operation (-40 °C to 85 °C). Each unit is programmed, serialized, and application-tested to guarantee identical initialization and operation as the OEM equivalent. TAA compliance ensures eligibility for U.S. government procurement. Backed by a limited lifetime warranty, this module provides the reliability and performance required for next-generation network infrastructure.
