Network architects choose the 100G QSFP28 ESR4 4x 25G NRZ QSFP-100G-SR4-S 850nm 300m MPO-12/UPC Module, Cisco for 100G Ethernet, data center interconnect and 5G transport networks: it runs 103.125Gbps (4x 25.78Gbps) over MMF and reaches 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.

On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-100G-SR4-S and works in Cisco systems out of the box. Standards compliance covers IEEE 802.3bm, QSFP28 MSA, SFF-8665, SFF-8636, SFF-8679.

Order this product as QSFP-ESR4-100G. 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.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed 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.

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.
