400G QSFP-DD QDD ZRPH 400GM Optical Transceiver

The 400G QSFP-DD QDD ZRPH 400GM Optical Transceiver is a QSFP-DD optical transceiver delivering 100G-31.5Gbaud（OTN STD） 200G-31.5Gbaud（OTN STD） 200G-63 Gbaud（OTN STD） 400G-63 Gbaud（OTN STD） 400G ZR 400G ZR+ over SMF. Operating at 1528.58-1567.54nm with a Duplex LC/UPC interface, it reaches its rated distance and is compliant with Open ZR+ MSA R1.0 and OTN, OIF 400ZR OIF-400ZR-01.0 and IEEE802.3cw R2.3 coherent standard, CMIS Rev 5.0, OIF C-CMIS 1.1. Built-in digital diagnostics give real-time access to operating parameters, making the module easy to deploy and maintain in data center interconnect, metro transport and carrier aggregation networks.

Built for data center interconnect, metro transport and carrier aggregation networks, this QSFP-DD module carries 100G-31.5Gbaud（OTN STD） 200G-31.5Gbaud（OTN STD） 200G-63 Gbaud（OTN STD） 400G-63 Gbaud（OTN STD） 400G ZR 400G ZR+ over SMF up to its rated distance per link. The Duplex LC/UPC interface and 1528.58-1567.54nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. For networks standardized on Ciena hardware, it is a drop-in equivalent of the 180-3360-900. The link runs QPSK/16QAM modulation, which keeps it aligned with current 400G switch silicon.

Compliance: Open ZR+ MSA R1.0 and OTN, OIF 400ZR OIF-400ZR-01.0 and IEEE802.3cw R2.3 coherent standard, CMIS Rev 5.0, OIF C-CMIS 1.1. For projects standardized on Ciena hardware, this product replaces the 180-3360-900 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.

Our part number for this module is QDD-ZRPH-400GM. 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.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

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.

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.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
