Extreme 10051H Compatible 1G SFP Transceiver Module

Extreme 10051H Compatible 1G SFP Transceiver Module

Built for hosts recognizing 10051H, this HT-manufactured SFP module delivers 1G transmission at 850nm. Its rated reach is 550m over OM2 MMF, with Duplex LC as the physical interface. The specifications and engineering guidance below support data-center designers evaluate optical reach, rack integration and host compatibility together, while keeping HT manufacture separate from the OEM cross-reference.

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.

The multimode channel should use the fiber grade associated with the stated 550m over OM2 MMF 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 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 -9.5~-3dBm; receiver sensitivity is < -17dBm. During commissioning, record the host diagnostic readings after the link has stabilized and compare them with those limits. DOM values are useful operational indicators, but they do not replace calibrated optical measurements when a link is marginal. Investigate unexpected loss through connector inspection, cleaning and a channel measurement before replacing the module. 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 1.25Gbps, wavelength 850nm, rated reach 550m over OM2 MMF.

Ordering Information

Use 10051H as the compatibility cross-reference and SFP1G-SX-85-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 Compatibility and Factory Testing

Compatibility testing for 10051H combines identification with a live link and available transmit, receive and alarm information. Connector condition is inspected separately. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.

Frequently Asked Questions

Is this an original Extreme transceiver?

No. It is an HT-manufactured compatible alternative for equipment that specifies 10051H, not an original Extreme-branded module.

Which fiber and connector are required?

Use Duplex LC with MMF. The specified maximum reach is 550m over OM2 MMF, 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.
