Applications
Network architects choose the 25G SFP28 SFP-25G-ER-I 40km 1310nm Duplex LC/UPC Industrial Module, Cisco for 25G Ethernet, data center interconnect and 5G transport networks: it runs 25.78Gbps over SMF and reaches 40km. The Duplex LC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. It is interoperable with Cisco platforms and replaces the Cisco part SFP-25G-ER-I directly.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part SFP-25G-ER-I and works in Cisco systems out of the box. Standards compliance covers SFF-8472, SFF-8432, SFF-8431.
Ordering Information
To order, quote SFP-25GER-31-I-CISCO 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.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
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.
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.
