The Black Box 10GBASE-SR SFP+ is a hot-swappable, single-LC multimode fiber transceiver for data-networking setups that need a 10-Gigabit Ethernet optical link.
Recommended For
- Network installers connecting 10GbE switches or servers over multimode fiber can use this module to add an LC fiber link to an SFP+ port; Black Box lists the LSP421 for up to 300 m over 850-nm multimode fiber.
- IT teams extending a 10GbE connection between nearby network closets or equipment rooms can use it when both endpoints support SFP+ and the installed fiber is multimode with LC connectors.
- Network technicians using a managed platform that exposes module diagnostics can choose it when they want digital diagnostic information and loopback support to help maintain a fiber link.
- Operators replacing or adding a hot-swappable SFP+ optical module in compatible networking or fiber-conversion equipment can use it for standards-based links up to 10Gbps.
