Brocade QSFP-40G-PLR4 Compatible 40G QSFP+ PLR4 Transceiver Module

Brocade QSFP-40G-PLR4 Compatible 40G QSFP+ PLR4 Transceiver Module

Built for hosts recognizing QSFP-40G-PLR4, this HT-manufactured QSFP+ module delivers 40G transmission at 1310nm. Its rated reach is 10km, with MTP/MPO-12 Male as the physical interface. The specifications and engineering guidance below support structured fiber installations preserve a documented and serviceable optical channel, while keeping HT manufacture separate from the OEM cross-reference.

Applications and Optical Link Design

Use this module for equipment interconnection over the specified single-mode fiber plant, including enterprise backbone, campus, metro or data-center interconnect links according to its rated distance. Confirm that both ends use the same optical standard and wavelength plan, and allow for connector, splice and patch-panel loss within the stated power budget.

Before deployment, check the host port type, supported data rate and firmware requirements. The 40G interface configuration must match the remote equipment; sharing a QSFP+ housing alone does not make two transceiver types interoperable.

Before commissioning, measure the complete single-mode channel against the stated budget for 10km. Inspect every MTP/MPO-12 Male connection and record diagnostic power where supported. Both ends must agree on rate, wavelength and optical standard.

Brocade Compatibility and Factory Testing

Compatibility testing for QSFP-40G-PLR4 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.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is -6~-1dBm; receiver sensitivity is <-14.4dBm; the stated optical power budget is 8.4dB. 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.

Structured Fiber Pathways and Serviceability

Treat the transceiver as part of the complete channel. Follow the intended patch-panel route, maintain bend control and leave service access around the port. Confirm connector polish and fiber type at every mated pair; a documented service allowance is preferable to excess slack concealed inside a rack. For this model, the principal parameters are data rate 44.4Gbps (4x 11.1Gbps), wavelength 1310nm, rated reach 10km.

Ordering Information

Quote HT part number QSFP-PLR4-40G together with OEM reference QSFP-40G-PLR4 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

Each QSFP-40G-PLR4 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.

Frequently Asked Questions

Is this an original Brocade transceiver?

No. It is an HT-manufactured compatible alternative for equipment that specifies QSFP-40G-PLR4, not an original Brocade-branded module.

Which fiber and connector are required?

Use MTP/MPO-12 Male with SMF. The specified maximum reach is 10km, 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.
