Applications
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. With its MTP/MPO-12 optical interface, the module works directly with the MMF infrastructure already installed in most facilities. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-100G-SR4-S directly.
Standards and Compatibility
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.
Ordering Information
To order, quote QSFP-ESR4-100G 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.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
Delivery
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.
Our Testing Process
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.
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.
