Core Product Positioning
The Cisco SFP-10G-ZR-I is a hot‑swappable industrial-grade multirate SFP+ optical transceiver designed for long-distance point-to-point transport over single-mode fiber. Optimized for carrier transport networks, remote outdoor sites, industrial networking, and edge infrastructure exposed to extreme temperature swings. This module supports both LAN PHY (10.3125 Gbps) and WAN PHY (9.953 Gbps) operation for seamless interoperability with SONET/SDH and OTN transport systems. Integrated DOM/DDM enables continuous real-time monitoring of optical operating parameters.
Important Notice: For fiber distances shorter than 40 km, inline optical attenuatorsmustbe deployed to prevent receiver saturation and permanent hardware damage.
