Cisco SFP-10G-SR

The Cisco SFP-10G-SR is a small form factor pluggable transceiver module designed for network switches and routers. It operates over multimode fiber optic cables to provide high-speed 10 Gigabit Ethernet connectivity between networking devices.

When used with standard OM3 multimode fiber, the SFP-10G-SR can transmit data reliably up to a distance of 300 meters. For older OM1 or OM2 fiber, the maximum supported distance is significantly shorter, usually around 26 to 82 meters.

Yes, the SFP-10G-SR is completely hot-swappable, meaning it can be inserted or removed from a compatible Cisco switch without powering down the device. This feature allows network administrators to easily replace failed modules or upgrade network capacity on the fly without causing network downtime.

This specific transceiver module operates at an optical wavelength of 850nm. This short wavelength is standard for SR (Short Range) optics, which are designed specifically for high-speed data transmission over short distances within data centers.
