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. 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
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
To order, quote QDD-PLR4-400G 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.
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.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
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.
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.
