Brocade SFP-25GLRS-31 Compatible 25G SFP28 LR-S Transceiver Module

Brocade SFP-25GLRS-31 Compatible 25G SFP28 LR-S Transceiver Module

Built for hosts recognizing SFP-25GLRS-31, this HT-manufactured SFP28 module delivers 25G transmission at 1310nm. Its rated reach is 300m, with Duplex LC as the physical interface. The specifications and engineering guidance below support installers plan a serviceable optical connection at the equipment rack, while keeping HT manufacture separate from the OEM cross-reference.

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 25.78125Gb/s, wavelength 1310nm, rated reach 300m.

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 25G interface configuration must match the remote equipment; sharing a SFP28 housing alone does not make two transceiver types interoperable.

Before commissioning, measure the complete single-mode channel against the stated budget for 300m. Inspect every Duplex LC connection and record diagnostic power where supported. Both ends must agree on rate, wavelength and optical standard.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is -5~2dBm; receiver sensitivity is <-8.5dBm; the stated optical power budget is 3.5W. 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.

Quality Assurance and Packaging

Each SFP-25GLRS-31 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.

Brocade Compatibility and Factory Testing

The module is checked for host recognition as SFP-25GLRS-31, 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.

Frequently Asked Questions

Is this an original Brocade transceiver?

No. It is an HT-manufactured compatible alternative for equipment that specifies SFP-25GLRS-31, not an original Brocade-branded module.

Which fiber and connector are required?

Use Duplex LC with SMF. The specified maximum reach is 300m, 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-25GLRS-31 together with OEM reference SFP-25GLRS-31 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.
