SFP-25G-ER-I Description
SFP-25G-ER-I is a Cisco industrial-temperature SFP28 optical transceiver designed for ultra-long-range 25G Ethernet over single-mode fiber. Supporting distances up to 40 kilometers, this module operates reliably from -40°C to 85°C, making it ideal for challenging outdoor or industrial environments. With a standard LC duplex connector and 1310nm wavelength, SFP-25G-ER-I ensures robust 25GbE links for metro aggregation, carrier backbone, or remote campus connectivity. It is fully compliant with IEEE 802.3cc and SFF-8402 standards, requires RS-FEC on the host for error-free 25G transmission, and is backed by a 5-year Cisco warranty. Commonly referred to as Cisco 25G ER SFP28 Industrial, this transceiver provides the performance and reliability demanded by telecom, utility, and critical infrastructure networks.
