Extreme Networks SFP-10GLRL-31 Compatible 10G SFP+ LRL Transceiver Module
Built for hosts recognizing SFP-10GLRL-31, this HT-manufactured SFP+ module delivers 10G transmission at 1310nm. Its rated reach is 2km, with Duplex LC as the physical interface. The specifications and engineering guidance below support project teams keep OEM references, delivery records and port schedules aligned, while keeping HT manufacture separate from the OEM cross-reference.

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 10Gbps, wavelength 1310nm, rated reach 2km.
Extreme Networks Compatibility and Factory Testing
The module is checked for host recognition as SFP-10GLRL-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.
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 10G interface configuration must match the remote equipment; sharing a SFP+ housing alone does not make two transceiver types interoperable.
Before commissioning, measure the complete single-mode channel against the stated budget for 2km. 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 -8.2~0.5dBm; receiver sensitivity is <-12.6dBm. 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. 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 Extreme Networks transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies SFP-10GLRL-31, not an original Extreme Networks-branded module.
Which fiber and connector are required?
Use Duplex LC with SMF. The specified maximum reach is 2km, 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-10GLRL-31 together with OEM reference SFP-10GLRL-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.
Quality Assurance and Packaging
Each SFP-10GLRL-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.
