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. With its Duplex LC/UPC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. It is interoperable with Arista Networks platforms and replaces the Arista Networks part SFP-25G-SR-E directly. The link runs 25G-NRZ modulation, which keeps it aligned with current 25G switch silicon.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Arista Networks part SFP-25G-SR-E and works in Arista Networks systems out of the box. Standards compliance covers 25GE SR Lite, 100G SR4 fan out to 4x25GE SR, eCPRI, SFP28 MSA, SFF-8472.
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.
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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
Our Testing Process
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.
