Specifications

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 40km design range before service.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is 0~6dBm; receiver sensitivity is <-18dBm; the stated optical power budget is 18dB. 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.

Mixed-Vendor Network Operation

A mixed-vendor optical link should be documented at both ends, not treated as one generic connection. Confirm which OEM identity each host expects and whether both ends use the same wavelength plan and optical standard. Related links locate equivalent hardware, but brand-specific identification must still be selected independently. For this model, the principal parameters are data rate 25.78Gbps, wavelength 1270nm-TX/1310nm-RX, rated reach 40km.

Brocade Compatibility and Factory Testing

The module is checked for host recognition as 25G-SFP28-BXU-40K-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.

Ordering Information

When ordering, specify 25G-SFP28-BXU-40K-I, SFP-25G23-BX40-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 25G-SFP28-BXU-40K-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.
