Gigabit Single-Mode Single-Fiber WDM 3KM Media Converter Pair

Wholesale Gigabit Ethernet fiber media converter pair for single-mode, single-fiber WDM links up to about 3 km. Each unit converts between copper RJ45 Gigabit Ethernet and optical fiber so campus, warehouse, or CCTV backbones can extend beyond copper distance limits. Sold as a matched TX/RX pair for WDM wavelength coordination on one fiber strand, reducing fiber-core count on short metro or building-to-building runs. Typical uses include ISP edge links, factory floors, and security NVR backhaul where ready-stock converters are preferred. Compact standalone form factor; plug-and-play copper side with Gigabit auto-negotiation. Specs focus: 1000 Mbps copper–fiber conversion, SM SF WDM, about 3 km reach, pair supply.
