Network architects choose the 100G QSFP28 LR4 4x 25G NRZ 1310nm 10km Duplex LC/UPC Industrial Module, Cisco for 100G Ethernet, data center interconnect and 5G transport networks: it runs 103.125Gbps (4x 25.78Gbps) over SMF and reaches 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-LR4-I directly. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.

This product is designed and tested to comply with IEEE 802.3ba 100GBASE-LR4, IEEE 802.3bm, QSFP28 MSA Compliant. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-100G-LR4-I.

Our part number for this module is QSFP-LR4-100G-I. 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.

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.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

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.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
