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

Overview

The D-Link DIS-S310LX is a single-mode SFP fiber transceiver designed to extend Gigabit Ethernet connections up to 10 kilometers using 1310 nm optics. It fits into the SFP slot of compatible switches or routers, enabling network teams to add long-distance fiber links without replacing existing hardware. Supporting a full 1.25 Gbps data rate and adhering to the IEEE 802.3z standard, this transceiver ensures smooth integration with equipment from various vendors that comply with the Multi-Source Agreement.

Its LC duplex connector works with standard single-mode fiber, allowing reuse of installed cabling or easy deployment of new fiber runs. The device operates reliably across a wide temperature range from -40 °C to 85 °C, making it suitable for challenging environments such as roadside cabinets, factory floors, and outdoor installations. The hot-swappable design minimizes downtime by allowing technicians to replace or install the transceiver without powering down the switch.
