Cisco Multi Mode 10G Transceiver / SFP-10G-SR

Industry-Standard 10G Multimode SFP+ for Short-Range Data Centre Links

The Cisco SFP-10G-SR is a genuine Cisco 10GBASE-SR SFP+ optical transceiver module — the industry’s most widely deployed 10 Gigabit multimode fibre transceiver for data centre, campus, and enterprise backbone applications. The Cisco 10GBASE-SR module supports a link length of 26 metres on standard FDDI-grade multimode fibre, up to 300 metres on 2000 MHzkm OM3 MMF, and up to 400 metres on 4700 MHzkm OM4 multimode fibre covering all standard intra-data-centre, inter-rack, and campus building distances without requiring single-mode infrastructure. Furthermore, the Cisco SFP-10G-SR operates at the universally accepted 850 nm wavelength using a VCSEL laser transmitter, making it fully interoperable with any IEEE 802.3ae 10GBASE-SR compliant equipment regardless of vendor. Consequently, it fits seamlessly into mixed-vendor network environments while maintaining Cisco platform certification and warranty compliance when used with Cisco switches, routers, and servers.

Maximum Port Density with Hot-Plug Flexibility

The SFP-10G-SR is the industry’s smallest 10G form factor, offering the greatest density per chassis and supporting a pay-as-you-populate model for investment protection and ease of technology migration.Additionally, the module is hot-swappable, plugging directly into an Ethernet SFP+ port of a Cisco switch enabling live insertion and removal without disrupting network operations or requiring chassis downtime. Moreover, Cisco’s quality identification (ID) feature enables a Cisco platform to identify whether the module is certified and tested by Cisco preserving the host device’s warranty and eliminating unsupported-transceiver warnings that add operational friction in enterprise environments.

Digital Optical Monitoring & Full Interoperability

The SFP-10G-SR supports digital optical monitoring capability for strong diagnostic capabilities providing real-time visibility into transmit power, receive power, laser bias current, supply voltage, and module temperature via the switch management interface. Furthermore, the module delivers optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link, protecting existing infrastructure investments during network upgrades and migrations. The duplex LC connector accepts standard 50/125 µm or 62.5/125 µm multimode fibre patch cables, making integration into any existing MMF infrastructure completely straightforward. Whether you are building a new 10G data centre fabric, upgrading a campus access layer, or expanding server connectivity, the Cisco SFP-10G-SR delivers the performance, density, and Cisco platform compatibility your 10G network demands.
