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 103.1Gbps, wavelength 1310nm-TX/1280nm-RX, rated reach 20km.
HPE Aruba Compatibility and Factory Testing
Factory verification starts with the expected QSFP-BX20-100G 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 BiDi interface is useful where only one fiber strand is available between two sites or racks. It must be paired with the complementary wavelength direction: one end transmits on the wavelength that the other end receives. Verify the paired part number, connector polish and fiber plant before installation, and measure link loss against the specified optical budget.
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.
BiDi operation saves a fiber strand but makes wavelength orientation critical. Record the part installed at each end and check its paired receive wavelength. The 20km rating still depends on total channel loss, including connectors and splices.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -4.3~4.5dBm. 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. 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.
Frequently Asked Questions
Is this an original HPE Aruba transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies QSFP-BX20-100G, not an original HPE Aruba-branded module.
Which fiber and connector are required?
Use Simplex LC with SMF. The specified maximum reach is 20km, 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-BX20-100G, QSFP-BX20-100G, 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
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.
