Project Documentation and Traceability
Large deployments are easier to audit when the order code, optical standard and endpoint record agree. Keep the OEM reference in the compatibility document and the HT part number on the packing list. Labels and carton groups can be arranged by rack or port plan so installers need not identify modules by appearance. For this model, the principal parameters are data rate 100G-31.5Gbaud（OTN STD） 200G-31.5Gbaud（OTN STD） 200G-63 Gbaud（OTN STD） 400G-63 Gbaud（OTN STD） 400G ZR 400G ZR+, wavelength 1528.58-1567.54nm, rated reach 400G ZR：120km 400G ZR+：1000km 100G-31.5Gbaud（OTN STD）：3300km 200G-31.5Gbaud（OTN STD）：800km 200G-63 Gbaud（OTN STD）：3000km 400G-63 Gbaud（OTN STD）：1300km.
Ciena Compatibility and Factory Testing
Factory verification starts with the expected 180-3360-900 identity and finishes with an operating host link. EEPROM data, diagnostic visibility and the stated optical parameters are assessed together. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
Applications and Optical Link Design
This coherent interface is suited to data-center interconnect, metro transport and managed DWDM links where the host platform supports the stated modulation and FEC modes. Design the optical line around the actual launch power, receiver range, OSNR requirement and span loss; the stated reach is not a substitute for a link-budget calculation. Use matching coherent modules and the appropriate DWDM channel plan at both ends.
Before deployment, check the host port type, supported data rate and firmware requirements. The 400G interface configuration must match the remote equipment; sharing a QSFP-DD housing alone does not make two transceiver types interoperable.
Coherent deployment requires a line-system review, not merely a matching connector. Confirm the DWDM channel, launch-power range, receiver limits, OSNR and FEC mode at both ends. Span loss and amplifier operation must remain inside the supported envelope, and stated reach should be validated against the actual route.
Optical Acceptance, Diagnostics and Handling
Use the electrical and optical limits in the specification table as the acceptance reference for this model. Digital diagnostics make later maintenance easier when baseline values are captured at installation. Save the initial readings with the port and OEM reference, then investigate meaningful changes rather than reacting to a single transient value. Diagnostic support depends on the host as well as the module, so unavailable fields should be confirmed with the platform documentation. Diagnostic monitoring is listed as Support. Before every insertion, keep dust caps in place until the patch lead is ready, avoid touching the optical end face and use an appropriate inspection and cleaning procedure. Do not look into an active optical interface.
Frequently Asked Questions
Is this an original Ciena transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies 180-3360-900, not an original Ciena-branded module.
Which fiber and connector are required?
Use Duplex LC/UPC with SMF. The specified maximum reach is 400G ZR：120km 400G ZR+：1000km 100G-31.5Gbaud（OTN STD）：3300km 200G-31.5Gbaud（OTN STD）：800km 200G-63 Gbaud（OTN STD）：3000km 400G-63 Gbaud（OTN STD）：1300km, subject to fiber quality and total link loss.
Can it be mixed with another wavelength or reach version?
Only when the two ends share the same optical standard, wavelength plan and supported data rate. Check the exact part numbers and link budget rather than relying only on the module form factor.
Ordering Information
When ordering, specify 180-3360-900, QDD-ZRPH-400GM, quantity and intended host platform. Project labels can repeat these details for receiving and asset records. Neutral labels, customer packaging and project-specific compatibility review are available on request.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.
Quality Assurance and Packaging
Each 180-3360-900 compatible module is inspected, powered up and functionally checked before protective packing. Dust caps and individual trays shield the interface during transport. Customer references, rack groups and project packing lists can be added for volume orders.
