Arista Networks SFP-10G-LRM-I Compatible 10G SFP+ LRM Transceiver Module

Arista Networks SFP-10G-LRM-I Compatible 10G SFP+ LRM Transceiver Module

The SFP-10G-LRM-I compatible module serves equipment requiring a 10G SFP+ interface with 1310nm optics and a 220m on OM3 / 1.4km on SMF rating. Connection is through Duplex LC. Product data, application guidance and factory verification are presented together to support data-center designers evaluate optical reach, rack integration and host compatibility together.

Applications and Optical Link Design

Typical deployments include switch-to-switch, switch-to-server and aggregation links inside a data hall or between adjacent equipment rooms. The Duplex LC interface connects to the specified multimode cabling, and the stated reach depends on fiber grade and link loss. Keep this interface on the matching multimode optical standard rather than connecting it directly to a single-mode wavelength or reach variant.

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.

For this multimode module, confirm fiber grade, modal bandwidth and total loss before commissioning. The 220m on OM3 / 1.4km on SMF figure applies only under suitable cabling conditions. Inspect every Duplex LC mating point and match the remote optical standard.

Quality Assurance and Packaging

Each SFP-10G-LRM-I 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.

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. 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.

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 10.3125Gbps, wavelength 1310nm, rated reach 220m on OM3 / 1.4km on SMF.

Ordering Information

Use SFP-10G-LRM-I as the compatibility cross-reference and SFP-10GLRM-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.

Arista Networks Compatibility and Factory Testing

The module is checked for host recognition as SFP-10G-LRM-I, 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 Arista Networks transceiver?

No. It is an HT-manufactured compatible alternative for equipment that specifies SFP-10G-LRM-I, not an original Arista Networks-branded module.

Which fiber and connector are required?

Use Duplex LC with MMF/SMF. The specified maximum reach is 220m on OM3 / 1.4km on SMF, 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.

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.
