Q&A

What is the reach of the Cisco SFP-25G-ER-I?

The Cisco SFP-25G-ER-I supports 40 km over Single-mode fiber (SMF), using Duplex LC/PC connectors. Confirm the fiber grade and the optical budget of the link before ordering.

What connector does the Cisco SFP-25G-ER-I use?

The Cisco SFP-25G-ER-I uses Duplex LC/PC. Standard duplex LC/PC patch cords are used for transmit and receive.

How does the Cisco SFP-25G-ER-I compare with the Cisco SFP-25G-SR-S?

The SFP-25G-ER-I reaches 40 km over Single-mode fiber (SMF), while the SFP-25G-SR-S reaches 70 m on OM3 / 100 m on OM4 over Multimode fiber (MMF). Pick the shortest reach that covers the link distance — going longer than needed costs more and adds optical budget margin you will not use.
