Brocade QSFP-4×10G-SR Compatible 10G QSFP+ SR Transceiver Module
Built for hosts recognizing QSFP-4×10G-SR, this HT-manufactured QSFP+ module delivers 10G transmission at 850nm. Its rated reach is 150m on OM4 / 100m on OM3, with MTP/MPO-12 Male as the physical interface. The specifications and engineering guidance below support project teams keep OEM references, delivery records and port schedules aligned, while keeping HT manufacture separate from the OEM cross-reference.

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 41.25Gbps (4x 10.3125Gbps), wavelength 850nm, rated reach 150m on OM4 / 100m on OM3.
Brocade Compatibility and Factory Testing
Compatibility testing for QSFP-4×10G-SR 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.
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 MTP/MPO-12 Male 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 10G interface configuration must match the remote equipment; sharing a QSFP+ housing alone does not make two transceiver types interoperable.
For this multimode module, confirm fiber grade, modal bandwidth and total loss before commissioning. The 150m on OM4 / 100m on OM3 figure applies only under suitable cabling conditions. Inspect every MTP/MPO-12 Male mating point and match the remote optical standard.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -7.6~-1dBm; receiver sensitivity is ≤-9.5dBm. 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.
Frequently Asked Questions
Is this an original Brocade transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies QSFP-4×10G-SR, not an original Brocade-branded module.
Which fiber and connector are required?
Use MTP/MPO-12 Male with MMF. The specified maximum reach is 150m on OM4 / 100m on OM3, 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 QSFP-4×10G-SR, QSFP-4×10G-SR, 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 QSFP-4×10G-SR 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.
