Designed for data center interconnect, metro transport and carrier aggregation networks, the 800G QSFP-DD QDD ZRH Optical Transceiver provides 850Gbps (8x 106.25Gbps) throughput in a QSFP-DD form factor. It operates at 1528.77~1567.13nm over SMF through a Duplex LC/UPC connector and supports link lengths up to Amplified: ≤120km Unamplified: ≤64km. The module meets QSFP-DD MSA Rev 6.3, IEEE 802.3-2022, OIF 800ZR, CMIS 5.2 and includes digital diagnostic monitoring for live status readout.

In data center interconnect, metro transport and carrier aggregation networks, the 800G QSFP-DD QDD ZRH Optical Transceiver delivers 850Gbps (8x 106.25Gbps) transmission over SMF with a reach of Amplified: ≤120km Unamplified: ≤64km. The Duplex LC/UPC interface and 1528.77~1567.13nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

Standards compliance covers QSFP-DD MSA Rev 6.3, IEEE 802.3-2022, OIF 800ZR, CMIS 5.2. The unit works in any equipment with a standard QSFP-DD interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

Our part number for this module is QDD-ZRH-800G. 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.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

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.

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.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
