Description
The AddOn Cisco® SFP-25G-LR-S-300M-AO is a high-performance, hot-swappable SFP28 optical transceiver designed for 25GBase-LRL Ethernet connectivity. Delivering up to 300 meters over single-mode fiber (SMF) using a 1310 nm wavelength via a duplex LC connector, this transceiver ensures seamless integration with Cisco® networking equipment.
Engineered to meet SFF-8402 and SFF-8472 standards, it features digital optical monitoring (DOM) for real-time diagnostics, robust ESD protection, and low-EMI metal housing for reliable operation in demanding environments. It is TAA compliant, RoHS lead-free, and guaranteed 100% compatible with Cisco® OEM equivalents — fully tested, uniquely serialized, and backed by a limited lifetime warranty.
Ideal for enterprise, access, and high-speed data center applications, the SFP-25G-LR-S-300M-AO combines exceptional performance, reliability, and cost-effectiveness in a compact, plug-and-play form factor.
