Applications
In 25G Ethernet, data center interconnect and 5G transport networks, the 25G SFP28 SFP-25G-SR-E 100m 850nm Duplex LC/UPC Enhanced Module, Arista delivers 25Gbps transmission over MMF with a reach of 70m@OM3/100m@OM4. The Duplex LC/UPC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. It is interoperable with Arista Networks platforms and replaces the Arista Networks part SFP-25G-SR-E directly.
Standards and Compatibility
This product is designed and tested to comply with 25GE SR Lite, 100G SR4 fan out to 4x25GE SR, eCPRI, SFP28 MSA, SFF-8472. It is interoperable with Arista Networks equipment and serves as a direct equivalent to the Arista Networks part number SFP-25G-SR-E.
Ordering Information
To order, quote SFP-25GSR-85-E 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.
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.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
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.
