Applications
The 25G SFP28 SFP-25G-SR-S 100m 850nm Duplex LC/UPC Module, Cisco is used in 25G Ethernet, data center interconnect and 5G transport networks, where it provides a 25.78Gbps link over MMF up to 100m@OM4/70m@OM3. The Duplex LC interface and 850nm 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-SR-S directly.
Standards and Compatibility
This product is designed and tested to comply with SFF-8472, SFF-8024, SFF-8431, SFF-8432. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number SFP-25G-SR-S.
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.
Package
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.
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.
Shipping and Lead Time
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
