Applications
Network architects choose the 400G QSFP-DD QDD 4X100G FR Si Optical Transceiver for 400G Ethernet data center and cloud network environments: it runs 400Gbps over SMF and reaches 2km. With its MPO-12 optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 8x50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with IEEE Std 802.3, QSFP-DD MSA, CMIS 4.0. It plugs into any standards-based QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
Our part number for this module is QDD-4X100G-FR-Si. 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.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
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.
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.
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.
