The 25G SFP28 300m 1310nm Duplex LC/UPC Module, Cisco is used in 25G Ethernet, data center interconnect and 5G transport networks, where it provides a 25.78125Gb/s link over SMF up to 300m. The Duplex LC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
This product is designed and tested to comply with SFF-8472, SFF-8024, SFF-8431, SFF-8432, IEEE 802.3 by, IEEE 802.3cc. It plugs into any standards-based SFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Our part number for this module is SFP-25GLRS-31. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
