Lantronix S6310-3340-AR POTS Copper to Fiber Media Converter, ION SA, SFP

Extend legacy analog telephone lines reliably over fiber for remote security, surveillance and monitoring sites with the Lantronix S6310-3340 POTS Copper to Fiber Media Converter. This ION-series media converter converts a standard RJ-11 POTS connection to an SFP fiber link, enabling analog voice grade signals to travel up to 3.11 miles while retaining Caller ID and ringing support. The S6310-3340 can be configured as FXO or FXS in the same product, so you can deploy matched pairs for central office or remote telephone endpoints without stocking multiple SKUs. SFP-based expandability lets you choose multimode or single-mode modules to match your network and distance needs, and the converter’s low 2W power consumption with 12V DC input keeps site power requirements minimal. Ideal for extending PBX lines, connecting field telephones, or integrating legacy voice paths into modern security and monitoring networks, the unit supports in-band management when paired with an ION chassis card. Deploy the Lantronix S6310-3340 in pairs to simplify voice extension for surveillance, remote monitoring, and temporary job-site communications—contact sales to order or discuss your network requirements.
