Intel SFP1G-SX-31-I Compatible 1G SFP Transceiver Module

The SFP1G-SX-31-I compatible module is intended for Intel platforms requiring a 1G SFP transceiver. It specifies wavelength 1310nm, reach 2km with Duplex LC through SMF/MMF.

OEM Part Number: SFP1G-SX-31-IHT Part Number: SFP1G-SX-31-I

Product Highlights

• Compatible alternative to Intel SFP1G-SX-31-I
• 1G connectivity at 1.25Gbps
• Optical wavelength: 1310nm
• Specified reach: 2km
• Duplex LC / SMF/MMF interface
• Operating temperature: -40 to 85°C (-40 to 185°F)
• Factory compatibility verification and optical performance testing before shipment

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 module is programmed for equipment that recognizes the SFP1G-SX-31-I part number. Before shipment, we check EEPROM identification, link establishment and diagnostic readouts, then verify transmit and receiver performance against the stated optical specifications. Host hardware and software revisions can affect third-party module acceptance, so customers can provide the switch model and software release for a compatibility check before ordering.

Quote HT part number SFP1G-SX-31-I together with OEM part number SFP1G-SX-31-I and the required quantity. Standard modules use our factory label; neutral labels, customer-branded packaging and project-specific compatibility coding are available on request. For mixed-brand installations, select the corresponding brand-specific page instead of assuming one EEPROM version fits every platform.

Each unit undergoes optical performance checks, compatibility verification and visual inspection before packing. Modules are supplied in protective blister trays or anti-static packaging and then cartoned for transport. Custom labels and project packing lists can be added for volume orders.

Standard products normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
