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. Compatibility with Cisco systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of SFP-25G-SR-S.
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.
Packaging Options
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.
Built to Your Spec
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.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
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.
