Core Product Positioning
The Cisco SFP-10G-ER-I is a hot‑swappable industrial-grade multirate SFP+ optical transceiver for medium-long haul point-to-point transmission over single-mode fiber. Designed for outdoor enclosures, industrial sites, mobile transport and carrier edge networks exposed to extreme temperature fluctuations. This module supports both LAN PHY (10.3125 Gbps 10GBASE-ER) and WAN PHY (9.953 Gbps 10GBASE-EW) to interoperate with SONET/SDH and OTN transport systems. Built-in DOM/DDM enables continuous real-time monitoring of optical operating parameters.
Important Reminder: For fiber spans shorter than 20 km, inline optical attenuators must be deployed to avoid receiver saturation and permanent hardware damage.
