The 100G QSFP28 ZR4 4x 25G NRZ QSFP-100G-ZR4-S 1310nm 80km Duplex LC/UPC Module, Cisco is a QSFP28 optical transceiver delivering 103.125Gbps (4x 25.78Gbps) over SMF. Operating at 1310nm with a Duplex LC/UPC interface, it reaches 80km and is compliant with QSFP28 MSA, SFF-8636, IEEE 802.3bm, CAUI-4. Built-in digital diagnostics give real-time access to operating parameters, making the module easy to deploy and maintain in data center interconnect, metro transport and carrier aggregation networks.

In data center interconnect, metro transport and carrier aggregation networks, the 100G QSFP28 ZR4 4x 25G NRZ QSFP-100G-ZR4-S 1310nm 80km Duplex LC/UPC Module, Cisco delivers 103.125Gbps (4x 25.78Gbps) transmission over SMF with a reach of 80km. With its Duplex LC/UPC 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 QSFP-100G-ZR4-S. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.

On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-100G-ZR4-S and works in Cisco systems out of the box. Standards compliance covers QSFP28 MSA, SFF-8636, IEEE 802.3bm, CAUI-4.

To order, quote QSFP-ZR4-100G 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.

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.

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.

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.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
