The 100G QSFP28 ESR4 4x 25G NRZ QSFP-100G-SR4-S 850nm 300m MPO-12/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 MMF up to 200m@OM3/300m@OM4. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. 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-SR4-S. 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 802.3bm, QSFP28 MSA, SFF-8665, SFF-8636, SFF-8679. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-100G-SR4-S.

Our part number for this module is QSFP-ESR4-100G. 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.

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.

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.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

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.
