Cisco SFP-10G-ER-I 10GBASE-ER Industrial SFP Module | SFP+ Optics — SFP-10G-ER-I

Keep critical 10 GbE links up in locations where temperature swings and long fiber spans challenge standard optics. Cisco SFP-10G-ER-I is a 10GBASE-ER industrial-temperature SFP module designed for single-mode deployments that need extended reach and dependable operation in harsher environments. With 1550 nm optics and an LC duplex connector, this module is suited for long-distance backbone links between buildings, campus edge connections, and remote network rooms. The ER reach class is built for extended optical budgets, helping teams connect distributed infrastructure without moving to more complex transport gear. For procurement teams, the value is straightforward: fewer compatibility questions, Cisco platform alignment, and a transceiver class chosen for long-reach enterprise and industrial deployments. For architects, it provides a clean way to preserve 10 GbE performance where distance and environmental conditions would otherwise force a redesign. Ideal For Connect remote network rooms across long single-mode fiber runs Link campus buildings where 10 GbE must span extended distances Support industrial or outdoor enclosures with wider temperature tolerance Provide long-reach uplinks in enterprise backbone architectures Why This Product 1 Industrial temperature rating for harsher deployment environments 2 10GBASE-ER reach for long single-mode fiber links 3 Cisco-qualified optics for platform alignment 4 LC duplex interface for straightforward fiber integration
