Applications
The 25G SFP28 SFP-25G-SR-E 100m 850nm Duplex LC/UPC Enhanced Module, Arista is used in 25G Ethernet, data center interconnect and 5G transport networks, where it provides a 25Gbps link over MMF up to 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. The link runs 25G-NRZ modulation, which keeps it aligned with current 25G switch silicon.
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
Our part number for this module is SFP-25GSR-85-E. 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.
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.
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.
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.
