D-Link DEM-S2810LR

Overview

The D-Link DEM-S2810LR is a 25GBASE-LR SFP28 transceiver designed to deliver 25 Gigabit Ethernet speeds over single-mode fiber. It supports fiber runs up to 10 kilometers using 9/125 µm single-mode cable, making it an excellent choice for extending high-bandwidth connections between buildings, data centers, or remote network points. Its hot-pluggable design allows for easy installation without interrupting network operations, ensuring seamless upgrades and expansions.

Key features

• Provides 25 Gigabit Ethernet connectivity for high-speed data transfer across long distances
• Supports single-mode fiber with a reach of up to 10 kilometers, ideal for enterprise and campus networks
• Hot pluggable module enables quick installation or replacement without powering down equipment
• Fully compliant with IEEE 802.3by, IEEE 802.3cc, and Multi-Source Agreement standards to ensure broad compatibility
• Operates at a 1310 nm wavelength to maintain a stable and reliable optical signal over extended fiber runs
• Compact SFP28 form factor fits easily into crowded switch racks, simplifying network upgrades
• Optimized for use with D-Link DMS 3130-30TS switches but compatible with other standards-based devices

Connectivity and compatibility

This transceiver fits into any switch or router with an open SFP28 slot that supports 25GBASE-LR modules. Its adherence to industry standards ensures it works smoothly with a wide range of networking equipment beyond D-Link models. The single-mode fiber interface supports long-distance links, making it suitable for connecting distant network segments without signal degradation.

Ideal uses and environments

The DEM-S2810LR is well suited for enterprise backbones, campus networks, and disaster recovery setups where consistent high-speed connectivity is critical. It works effectively in environments requiring long-reach fiber connections, such as linking separate buildings or data halls. Network administrators looking to upgrade bandwidth without replacing existing switch chassis will find this transceiver a practical and cost-effective solution.

Returns are accepted within 30 days of delivery. Items must be unused, in the same condition received, with tags, manuals, accessories, and original, unaltered packaging. Any item kept will be deducted from the refund. Start a return by sending us an email. Items sent back without approval may be refused or returned to the sender.

Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.

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.
