Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 LR 4x 25G NRZ QSFP-100G-LR-S 1310nm 10km Duplex LC/UPC Single Lambda Module, Cisco delivers 103.125Gbps (4x 25.78Gbps) transmission over SMF with a reach of 10km. With its Duplex 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 QSFP-100G-LR-S directly. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-100G-LR-S and works in Cisco systems out of the box. Standards compliance covers QSFP28 MSA, SFF-8636, IEEE 802.3cu, CAUI-4.
Ordering Information
Order this product as QSFP-LR-100G. 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.
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.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
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.
