Applications
Built for 25G Ethernet, data center interconnect and 5G transport networks, this SFP28 module carries 25.78Gbps over SMF up to 20km per link. With its Simplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. For networks standardized on Cisco hardware, it is a drop-in equivalent of the SFP-25GBX-D-20.
Standards and Compatibility
Compliance: eCPRI, SFF-8472, SFF-8432, SFF-8431. For projects standardized on Cisco hardware, this product replaces the SFP-25GBX-D-20 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
Our part number for this module is SFP-25G32-BX20. 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.
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.
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
