Yes. It is a hot-swappable input/output device, so it can be inserted into or removed from a compatible Cisco SFP+ port without powering down the switch or router.

No. Cisco specifies that the SFP-10G-SR-S does not support FCoE. It is intended for 10 Gigabit Ethernet connectivity over multimode fiber rather than Fibre Channel over Ethernet applications.

The module uses dual LC/PC optical connectors and operates at 850 nm. Its transmit and receive wavelength range is 840 to 860 nm, making it suitable for standard 10GBASE-SR multimode fiber links.

It supports multimode fiber only. Typical maximum distances are 33 m on OM1, 82 m on OM2, 300 m on OM3, 400 m on OM4, and 400 m on OM5. Cisco also notes 26 m on standard FDDI-grade MMF.

The Cisco SFP-10G-SR-S is a 10GBASE-SR SFP+ transceiver for short-range 10 Gigabit Ethernet over multimode fiber. It uses an 850 nm wavelength, dual LC connectors, supports hot-swapping, and is designed for data center, enterprise, and service provider environments.
