QSFP-SR4-100GMJuniper Networks QSFP-SR4-100GM Compatible 100G QSFP28 SR4 Transceiver Module
Built for hosts recognizing QSFP-SR4-100GM, this HT-manufactured QSFP28 module delivers 100G transmission at 850nm. Its rated reach is 100m, with MPO-12 as the physical interface. The specifications and engineering guidance below support structured fiber installations preserve a documented and serviceable optical channel, while keeping HT manufacture separate from the OEM cross-reference.

Applications and Optical Link Design
Typical deployments include switch-to-switch, switch-to-server and aggregation links inside a data hall or between adjacent equipment rooms. The MPO-12 interface connects to the specified multimode cabling, and the stated reach depends on fiber grade and link loss. Keep this interface on the matching multimode optical standard rather than connecting it directly to a single-mode wavelength or reach variant.
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.
The multimode channel should use the fiber grade associated with the stated 100m reach. Keep the MPO-12 end faces clean and avoid tight bends. Different multimode standards are not interchangeable merely because they share a connector.
Juniper Networks Compatibility and Factory Testing
Compatibility testing for QSFP-SR4-100GM 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.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -8.4~2.4 dBm; receiver sensitivity is ＜-10.3 dBm; the stated optical power budget is 1.9dB. 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.
Structured Fiber Pathways and Serviceability
Treat the transceiver as part of the complete channel. Follow the intended patch-panel route, maintain bend control and leave service access around the port. Confirm connector polish and fiber type at every mated pair; a documented service allowance is preferable to excess slack concealed inside a rack. For this model, the principal parameters are data rate Dual Rate 103.1Gbps and 112Gbps, wavelength 850nm, rated reach 100m.
Ordering Information
Quote HT part number QSFP-SR4-100GM together with OEM reference QSFP-SR4-100GM 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.
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
Quality control covers the optical or electrical interface, host identification and operating link. The verified unit is then individually protected and cartoned. 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-SR4-100GM, not an original Juniper Networks-branded module.
Which fiber and connector are required?
Use MPO-12 with MMF. The specified maximum reach is 100m, 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.
