Applications
The Juniper Compatible 400G QSFP-DD QDD PLR4 Optical Transceiver is used in data center interconnect, metro transport and carrier aggregation networks, where it provides a 425Gbps (4x 106.25Gbps) link over SMF up to 10km. The MPO-12/APC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Compatibility with Juniper Networks systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QDD-4X100G-LR. The link runs 8x50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Juniper Networks part QDD-4X100G-LR and works in Juniper Networks systems out of the box. Standards compliance covers QSFP-DD MSA HW Rev 5.1, QSFP-DD, CMIS Rev 5.0, IEEE 802.3cu, IEEE 802.3bs.
Ordering Information
Order this product as QDD-PLR4-400G. 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.
How We Ship
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.
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.
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.
