Network architects choose the 25G SFP28 SFP-25G-ER-I 40km 1310nm Duplex LC/UPC Industrial Module, Cisco for 25G Ethernet, data center interconnect and 5G transport networks: it runs 25.78Gbps over SMF and reaches 40km. The Duplex LC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. For networks standardized on Cisco hardware, it is a drop-in equivalent of the SFP-25G-ER-I.
This product is designed and tested to comply with SFF-8472, SFF-8432, SFF-8431. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number SFP-25G-ER-I.
Order this product as SFP-25GER-31-I-CISCO. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
