In 25G Ethernet, data center interconnect and 5G transport networks, the 25G SFP28 SFP-25G-ER-S-I 30km 1310nm Duplex LC/UPC Industrial Module, Cisco delivers 25.78Gbps transmission over SMF with a reach of 30km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. For networks standardized on Cisco hardware, it is a drop-in equivalent of the SFP-25G-ER-S-I.
On the compatibility side, this unit is the practical equivalent of the Cisco part SFP-25G-ER-S-I and works in Cisco systems out of the box. Standards compliance covers SFF-8472, SFF-8432, SFF-8431.
To order, quote SFP-25GERL-31-I 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.
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
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.
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.
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.
