TP-Link TL-SM311LS MiniGBIC Fiber Module Card, LC Duplex, up to 10km Distance

Extend your LAN and secure remote device connectivity with the TP‑Link TL‑SM311LS MiniGBIC SFP module. Designed for installers and IT teams who need reliable, long‑reach fiber links for security, surveillance and monitoring systems, this SFP module delivers up to 10 km of single‑mode connectivity using an LC/UPC duplex interface. With a 1.25 Gbps data rate and a 1310 nm wavelength, the TL‑SM311LS provides consistent Gigabit performance for IP cameras, access control panels and distributed switches. The hot‑swappable miniGBIC design makes upgrades and replacements simple, while DDMI (Digital Diagnostics Monitoring Interface) gives you real‑time visibility into optical parameters to reduce mean‑time‑to‑repair. Compatible with TP‑Link JetStream switches and media converters, this module streamlines deployments and inventory for managed network environments. Ideal for enterprise networking, remote surveillance points, and campus backbone links — add the TP‑Link TL‑SM311LS to your toolkit to extend fiber reach and keep critical monitoring systems online.
