SFP Module Cisco SFP-10G-SR= 10GBASE-SR

The Cisco SFP-10G-SR= is a 10GBASE-SR SFP+ optical transceiver designed for short-range 10-Gigabit Ethernet links in data centres, enterprise server rooms and service provider transport environments. It is a hot-swappable module that fits into SFP+ ports on Cisco switches and provides optical interoperability with 10GBASE XENPAK, X2 and XFP interfaces on the same link. The module supports multimode fibre connections with a maximum reach of 300 m at a wavelength of 850 nm and is covered by a 5-year standard warranty.

Advantages

The SFP-10G-SR= offers compact dimensions suitable for high-density switch ports and enables easy installation and replacement without disrupting operations due to its hot-swappable design. It provides interoperable 10-Gigabit Ethernet connectivity across multiple optical interface formats and supports short-range multimode fibre links up to 300 m, making it suitable for common intra-building and campus connections. The module's lightweight construction and standard form factor simplify integration into existing network equipment.
