Applications
In 25G Ethernet, data center interconnect and 5G transport networks, the 25G SFP28 SFP-25G-LR-I 10km 1310nm Duplex LC/UPC Industrial Module, Cisco delivers 25.78Gbps transmission over SMF with a reach of 10km. The Duplex LC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. It is interoperable with Cisco platforms and replaces the Cisco part SFP-25G-LR-I directly.
Standards and Compatibility
This product is designed and tested to comply with SFF-8472, SFF-8402, SFF-8432, SFF-8431, CEI-28G-VSR. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number SFP-25G-LR-I.
Ordering Information
Our part number for this module is SFP-25GLR-31-I-CISCO. 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.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
