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 100G interface configuration must match the remote equipment; sharing a QSFP28 housing alone does not make two transceiver types interoperable.
For this coherent interface, document the wavelength plan and modulation or FEC settings before commissioning. Measure span loss and verify adequate OSNR. Interoperability depends on compatible coherent modes as well as form factor, so another coherent part number must not be substituted without engineering review.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is 0dBm; the stated optical power budget is unamplified：30dB. A sound acceptance record includes link state, diagnostic temperature, supply voltage and transmit or receive levels where the host exposes them. Compare the readings with the stated ranges rather than treating any received light as proof of adequate margin. Persistent alarms or borderline values should trigger an end-face and complete-channel inspection. Diagnostic monitoring is listed as Supported. 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.
Procurement and Asset Identification
A useful purchase order identifies the host platform, expected OEM code and optical standard separately. This prevents a module with the same housing but another wavelength, reach or identification profile from being substituted. For mixed deployments, keep one order line per OEM reference and reconcile each received unit with its intended port. For this model, the principal parameters are data rate 100Gbps, wavelength 100GHz gird：1528.77~1566.31nm 50GHz gird：1528.77~1566.72nm, rated reach unamplified：≤120km amplified：≤300km.
Nokia Compatibility and Factory Testing
Factory verification starts with the expected QSFP-ZRH-100G-S 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.
Ordering Information
Quote HT part number QSFP-ZRH-100G together with OEM reference QSFP-ZRH-100G-S and quantity. Add the host model and software release when pre-order verification is required. Neutral labels, customer packaging and project-specific compatibility review are available on request.
Quality Assurance and Packaging
Each QSFP-ZRH-100G-S 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.
Frequently Asked Questions
Is this an original Nokia transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies QSFP-ZRH-100G-S, not an original Nokia-branded module.
Which fiber and connector are required?
Use Duplex LC/UPC with Duplex SMF. The specified maximum reach is unamplified：≤120km amplified：≤300km, 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.
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.
