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 10.31Gbps, wavelength 1310nm, rated reach 2km.

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.

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 <-14.4dBm; the stated optical power budget is 6.2dB. 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

Before packing, the module receives interface inspection, identification and link checks. Protective packaging avoids pressure on the connector and latch. Customer references, rack groups and project packing lists can be added for volume orders.

Dell Compatibility and Factory Testing

Factory verification starts with the expected SFP-10GLRL-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.

Frequently Asked Questions

Ordering Information

When ordering, specify SFP-10GLRL-31-I, SFP-10GLRL-31-I, quantity and intended host platform. Project labels can repeat these details for receiving and asset records. 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.
