D-Link DIS-S310LX

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.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
