Applications
Network architects choose the 25G SFP28 SFP-25G-SR-S 100m 850nm Duplex LC/UPC Module, Cisco for 25G Ethernet, data center interconnect and 5G transport networks: it runs 25.78Gbps over MMF and reaches 100m@OM4/70m@OM3. With its Duplex LC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. It is interoperable with Cisco platforms and replaces the Cisco part SFP-25G-SR-S directly.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part SFP-25G-SR-S and works in Cisco systems out of the box. Standards compliance covers SFF-8472, SFF-8024, SFF-8431, SFF-8432.
Ordering Information
Our part number for this module is SFP-25GSR-85. 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.
Quality Assurance
Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
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.
Delivery
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.
