The 25G SFP28 20km 1310nm Duplex LC/UPC Industrial Module, Arista is used in 25G Ethernet, data center interconnect and 5G transport networks, where it provides a 25.78Gbps link over SMF up to 20km. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
This product is designed and tested to comply with SFF-8402, SFF-8472, MSA SFP+. It plugs into any standards-based SFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Order this product as SFP-25GELR-31-I. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
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.
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.
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
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.
