The Cisco C21 C22 Compatible QSFP28 100G DWDM PAM4 80km (Require EDFA and TDCM) Duplex CS/UPC SMF Transceiver Module is used in data center interconnect, metro transport and carrier aggregation networks, where it provides a 100Gbps (2x50G) link over twinax copper up to 80km with EDFA and TDCM. The Duplex CS/UPC interface and 1560.61nm,1559.79nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs PAM4 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-8636, SFF-8024. It plugs into any standards-based QSFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

Our part number for this module is DW2-QSFP100G80-2122. 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.

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.

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.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

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.
