Applications
Network architects choose the Cisco C21 C22 Compatible QSFP28 100G DWDM PAM4 80km (Require EDFA and TDCM) Duplex CS/UPC SMF Transceiver Module for data center interconnect, metro transport and carrier aggregation networks: it runs 100Gbps (2x50G) over twinax copper and reaches 80km with EDFA and TDCM. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.
Standards and Compatibility
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.
Ordering Information
Order this product as DW2-QSFP100G80-2122. 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.
Quality Assurance
Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
Logistics
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.
