Applications
Network architects choose the 25G SFP28 SFP-25GBX-D-20 20km 1330nm-TX/1270nm-RX Simplex LC/UPC Module, Cisco for 25G Ethernet, data center interconnect and 5G transport networks: it runs 25.78Gbps over SMF and reaches 20km. With its Simplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with Cisco platforms and replaces the Cisco part SFP-25GBX-D-20 directly.
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
To order, quote SFP-25G32-BX20 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.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
OEM and Custom Orders
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.
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.
