As of my last knowledge update in January 2022, the Cisco SFP-10G-SR-S is a 10 Gigabit Ethernet short-range transceiver module designed for use with multimode fiber optic cables. The "SR" in its name stands for "short range." The typical operating range for SFP-10G-SR-S is around 300 meters (m) over OM3 multimode fiber and 400m over OM4 multimode fiber.

Keep in mind that specifications and product details may change over time, so it's advisable to check the official Cisco documentation or contact Cisco support for the most accurate and up-to-date information regarding the SFP-10G-SR-S module's range.
