The EX-SFP-10GE-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.

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.
The multimode channel should use the fiber grade associated with the stated 220m on OM3 / 1.4km on SMF reach. Keep the Duplex LC end faces clean and avoid tight bends. Different multimode standards are not interchangeable merely because they share a connector.
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.
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.
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.
Quote HT part number SFP-10GLRM-31-I together with OEM reference EX-SFP-10GE-LRM-I 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.
The module is checked for host recognition as EX-SFP-10GE-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.
No. It is an HT-manufactured compatible alternative for equipment that specifies EX-SFP-10GE-LRM-I, not an original Juniper Networks-branded module.
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.
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.
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.
