Import Ethernet Fiber Optic Media Converter — Buy in Bulk from Supplier in China

The Ethernet fiber optic media converter from Shanghai Sun Telecommunication Co., Ltd. transforms electrical signals from copper Ethernet cables into optical signals for fiber optic transmission, and vice versa, supporting data rates up to 1 Gbps. It complies with IEEE 802.3u Fast Ethernet standards and operates over single-mode and multimode fiber with wavelengths of 1310 nm and 1550 nm. The device accepts standard RJ-45 connections and uses SC or LC fiber connectors, depending on the model variant.

The unit is constructed with industrial-grade metal housing rated for operating temperatures between -10°C and 70°C, making it suitable for uncontrolled environments such as factories or outdoor cabinets. Power input is typically 12V DC or 24V DC, with reverse polarity protection. The converter supports full-duplex communication and auto-negotiation for speed and duplex settings. Typical fiber reach is 2 km over multimode and up to 40 km over single-mode fiber, consistent with industry norms for unmanaged media converters.

This converter is commonly purchased by network integrators for upgrading legacy copper networks to fiber backbone segments in industrial automation, security surveillance, and campus-wide LANs. Buyers typically require units with DIN-rail mounting options and surge protection. Minimum order quantities are not stated but are often negotiable for bulk deployments. Trade terms such as FOB Shanghai or CIF port of destination are standard, with payment via T/T or L/C common for international orders.
