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. For networks standardized on Arista Networks hardware, it is a drop-in equivalent of the SFP-25G-SR-E.
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
Order this product as SFP-25GSR-85-E. 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.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
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.
