Applications
The 100G QSFP28 LR4 4x 25G NRZ QSFP-100G-LR4-S 1310nm 10km Duplex LC/UPC Module, Cisco is used in 100G Ethernet, data center interconnect and 5G transport networks, where it provides a 103.125Gbps (4x 25.78Gbps) link over SMF up to 10km. With its Duplex LC/UPC 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 QSFP-100G-LR4-S directly.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-100G-LR4-S and works in Cisco systems out of the box. Standards compliance covers QSFP28 MSA, SFF-8636, IEEE 802.3‑2012, PSM4 MSA, CAUI-4.
Ordering Information
Order this product as QSFP-LR4-100G-CISCO. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
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.
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.
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.
