Applications

The 25G SFP28 SFP-25G-BX40U-I 40km 1270nm-TX/1310nm-RX Simplex LC/UPC Industrial Module, Cisco is used in 25G Ethernet, data center interconnect and 5G transport networks, where it provides a 25.78Gbps link over SMF up to 40km. The Simplex LC interface and 1270nm-TX/1310nm-RX 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-BX40U-I directly.

Standards and Compatibility

On the compatibility side, this unit is the practical equivalent of the Cisco part SFP-25G-BX40U-I and works in Cisco systems out of the box. Standards compliance covers SFF-8472, SFF-8402, SFF-8432, SFF-8431, CEI-28G-VSR.

Ordering Information

Our part number for this module is SFP-25G23-BX40-I-CISCO. 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.

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.

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.
