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. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. 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
Compliance: 25GE SR Lite, 100G SR4 fan out to 4x25GE SR, eCPRI, SFP28 MSA, SFF-8472. For projects standardized on Arista Networks hardware, this product replaces the SFP-25G-SR-E directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
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.
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.
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.
Shipping and Lead Time
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
