Specifications

Rack Integration and Service Access

Plan the fiber route before removing connector protection. The patch lead should follow its manager without pulling on the transceiver, while leaving space to release the latch and service adjacent ports. Protect the end face until final connection and avoid tight bends immediately behind warm exhaust air. For this model, the principal parameters are data rate 106.25Gbps, wavelength 1304.58nm-TX/1309.14nm-RX, rated reach 40km on OS2.

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 40km on OS2 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 1.7~7.1dBm; the stated optical power budget is 17.7dB. Digital diagnostics make later maintenance easier when baseline values are captured at installation. Save the initial readings with the port and OEM reference, then investigate meaningful changes rather than reacting to a single transient value. Diagnostic support depends on the host as well as the module, so unavailable fields should be confirmed with the platform documentation. 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.

Quality Assurance and Packaging

Each QSFP-BX40-100G 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.

Juniper Compatibility and Factory Testing

Compatibility testing for QSFP-BX40-100G 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.

Frequently Asked Questions

Ordering Information

Use QSFP-BX40-100G as the compatibility cross-reference and QSFP-BX40-100G as the HT ordering identity. Keep other reaches or wavelength directions on separate order lines. 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.
