Applications
Network architects choose the 100G QSFP28 ZR4 4x 25G NRZ QSFP-100G-ZR4-S 1310nm 80km Duplex LC/UPC Module, Cisco for data center interconnect, metro transport and carrier aggregation networks: it runs 103.125Gbps (4x 25.78Gbps) over SMF and reaches 80km. With its Duplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Compatibility with Cisco systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QSFP-100G-ZR4-S.
Standards and Compatibility
This product is designed and tested to comply with QSFP28 MSA, SFF-8636, IEEE 802.3bm, CAUI-4. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-100G-ZR4-S.
Ordering Information
Our part number for this module is QSFP-ZR4-100G. 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.
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.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
