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.
The industrial temperature rating makes this version appropriate for controlled outdoor cabinets, transport nodes and other installations exposed to wider ambient temperature variation. Adequate airflow, protected cable routing and host-platform temperature limits still apply.
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
For this model, the specified transmit-power range is -8~-4dBm. 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. 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 C-Band 5THz DWDM Tunable, rated reach 80km (unamplified)300km (amplified).
Juniper Networks Compatibility and Factory Testing
Compatibility testing for QSFP-ZR-100G-S-I combines identification with a live link and available transmit, receive and alarm information. Connector condition is inspected separately. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
Ordering Information
When ordering, specify QSFP-ZR-100G-S-I, QSFP-ZR-100G-S-I, 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.
Quality Assurance and Packaging
Each QSFP-ZR-100G-S-I 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 Juniper Networks transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies QSFP-ZR-100G-S-I, not an original Juniper Networks-branded module.
Which fiber and connector are required?
Use Duplex LC/UPC with Duplex SMF. The specified maximum reach is 80km (unamplified)300km (amplified), 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.
