In data center interconnect, metro transport and carrier aggregation networks, the Cisco C21 C22 Compatible QSFP28 100G DWDM PAM4 80km (Require EDFA and TDCM) Duplex CS/UPC SMF Transceiver Module delivers 100Gbps (2x50G) transmission over twinax copper with a reach of 80km with EDFA and TDCM. With its Duplex CS/UPC optical interface, the module works directly with the twinax copper infrastructure already installed in most facilities. 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.

Standards compliance covers IEEE 802.3bm, QSFP28 MSA, SFF-8636, SFF-8024. The unit works in any equipment with a standard QSFP28 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

To order, quote DW2-QSFP100G80-2122 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.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

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.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
