Applications
In data center interconnect, metro transport and carrier aggregation networks, the Juniper Compatible 400G QSFP-DD QDD PLR4 Optical Transceiver delivers 425Gbps (4x 106.25Gbps) transmission over SMF with a reach of 10km. With its MPO-12/APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with Juniper Networks platforms and replaces the Juniper Networks part QDD-4X100G-LR directly. The link runs 8x50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: QSFP-DD MSA HW Rev 5.1, QSFP-DD, CMIS Rev 5.0, IEEE 802.3cu, IEEE 802.3bs. For projects standardized on Juniper Networks hardware, this product replaces the QDD-4X100G-LR directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
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.
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.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
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.
