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 10.3125Gbps, wavelength 1490nm-TX/1550nm-RX, rated reach 80km.
Cisco Compatibility and Factory Testing
The module is checked for host recognition as SFP-10G-BX80U-I, link establishment and diagnostic reporting. Physical cage fit alone is not treated as evidence of compatibility. 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.
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.
This single-fiber interface must be paired with the complementary wavelength direction. One end transmits on the wavelength the other receives. Verify connector polish and measure loss over the 80km design range before service.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is 0~5dBm; receiver sensitivity is <-23dBm; the stated optical power budget is 23dB. 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 Cisco transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies SFP-10G-BX80U-I, not an original Cisco-branded module.
Which fiber and connector are required?
Use Simplex LC with SMF. The specified maximum reach is 80km, 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
Quote HT part number SFP-10G45-BX80-I together with OEM reference SFP-10G-BX80U-I 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.
