SFP-25G-ER-I Description
The SFP-25G-ER-I is a Cisco 25GBASE-ER SFP28 industrial-temperature transceiver for long single-mode links between sites. The module reaches 40 km over ITU-T G.652 fiber at 1310 nm on dual LC/PC connectors, draws up to 1.5W and operates from -40 to 85 degrees C. The module needs RS-FEC on the host port for full 25G reach, and links beyond 30 km count as engineered links.

Application Scenarios
Between two sites joined by a duplex G.652 fiber pair of up to 40 km, the module carries a 25 Gigabit Ethernet link from a switch SFP28 port that has RS-FEC enabled.
In a roadside or utility cabinet without climate control, the industrial -40 to 85 degrees C rating lets the module serve as the 25G uplink back to a central aggregation switch.

SFP-25G-ER-I carries 25G over a duplex G.652 single-mode pair to 40 km, while SFP-10/25G-LR-I stops at 10 km but also runs at 10G, so a link that must go past 10 km at 25G needs SFP-25G-ER-I and a link that must also run 10G needs SFP-10/25G-LR-I. Both are industrial-temperature optics and both need RS-FEC on the host port for full 25G reach. Where only one fiber strand is available, the 40 km option is the BiDi pair of SFP-25G-BX40D-I at one end and SFP-25G-BX40U-I at the other, each drawing 1.9W against 1.5W for SFP-25G-ER-I. Spans beyond 30 km count as engineered links.
Ordering Checklist
- Host support: Confirm the host belongs to one of the listed families: Cisco 8000 Series, 8010 Series, 8400 Secure Router, ASR9000, C9350, C9500, N9300, N9500, NCS4000, NCS540, NCS560 or NCS5500. Supported hosts are listed per optic PID, so a host that takes another SFP28 module is not covered by default.
- Fiber and connector: Use duplex G.652 single-mode fiber with LC/PC or LC/UPC patch cords, not APC. APC patch cords are not supported on this optic, and a single-fiber link needs the BiDi pair instead.
