Applications
Built for 25G Ethernet, data center interconnect and 5G transport networks, this SFP28 module carries 25.78Gbps over SMF up to 10km per link. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. For networks standardized on Cisco hardware, it is a drop-in equivalent of the SFP-25G-LR-S.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part SFP-25G-LR-S and works in Cisco systems out of the box. Standards compliance covers MSA Compliant, CPRI, eCPRI.
Ordering Information
Our part number for this module is SFP-25GLR-31. 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.
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.
Customization Service
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.
Worldwide Delivery
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.
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.
