Specifications

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.

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.

The single-mode link budget should include fiber attenuation, connectors, splices and panels over the intended 20km route. Keep the Duplex LC interface clean and match the remote optical standard. Consider receiver overload as well as insufficient power on short links.

Quality Assurance and Packaging

Quality control covers the optical or electrical interface, host identification and operating link. The verified unit is then individually protected and cartoned. Customer references, rack groups and project packing lists can be added for volume orders.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is -2~4dBm; receiver sensitivity is <-12.6dBm; the stated optical power budget is 12.4dB. 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.

Data-Center Optical Design and Airflow

Select the module by optical standard, reach and rack layout. Check the complete fiber channel, including panels and connectors, and keep dense bundles from blocking front-panel airflow. Account for listed power consumption and preserve enough space to remove a module without disturbing adjacent links. For this model, the principal parameters are data rate 1/10.3125Gbps, wavelength 1310nm, rated reach 20km.

Ordering Information

Use SFP-10GMELR-31-I as the compatibility cross-reference and SFP-10GMELR-31-I 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.

Extreme Networks Compatibility and Factory Testing

Factory verification starts with the expected SFP-10GMELR-31-I identity and finishes with an operating host link. EEPROM data, diagnostic visibility and the stated optical parameters are assessed together. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
