Built for 25G Ethernet, data center interconnect and 5G transport networks, this SFP28 module carries 25Gbps over MMF up to 400m@OM4/300m@OM3 per link. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. 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-10/25G-CSR-S.

This product is designed and tested to comply with SFF-8472, SFF-8024, SFF-8431, SFF-8432, IEEE802.3by. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number SFP-10/25G-CSR-S.

To order, quote SFP-25GMCSR-85 together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.

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.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.

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.

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.
