D-Link 1000Base-LX 10km Single-Mode SFP Fiber Transceiver

The D-Link DIS-S310LX is a single-mode SFP fiber transceiver that pushes Gigabit Ethernet traffic up to 10 kilometers through 1310 nm optics. It plugs directly into the SFP slot of a compatible switch or router, giving network teams an easy path to long-reach fiber without changing existing hardware.

The module supports a full 1.25 Gbps data rate and follows the IEEE 802.3z standard, so it integrates smoothly with equipment from D-Link and other vendors that honor the Multi-Source Agreement. Its LC duplex connector works with standard single-mode fiber runs, letting you reuse installed cabling or build fresh links with familiar components.

An operating range from -40 °C to 85 °C makes the DIS-S310LX suitable for environments where traditional office-grade optics cannot cope. Deploy it in roadside cabinets, factory floors, rail stations, or outdoor camera enclosures and expect stable performance across wide temperature swings.

The hot-swappable design keeps downtime low. Technicians can insert or remove the transceiver while the switch remains powered, making upgrades or replacements quick and nondisruptive. Compliance with RoHS directives and industry MSA guidelines simplifies certification and ensures predictable behavior across mixed-vendor networks.

Use the DIS-S310LX to extend campus backbones, link smart city devices, or tie together industrial control systems. Wherever reliable fiber connectivity over long distance is required, this D-Link transceiver delivers the reach, durability, and ease of use that professionals rely on.
