1 GbE SFP Transceiver for 10 km Single-Mode Links

This StarTech SFP module delivers 1 Gbps over single-mode fiber using a 1310 nm wavelength and LC duplex connector. It complies with IEEE 802.3z 1000BASE-LX and is designed for network links up to 10 km. The uncoded MSA design targets compatibility with a wide range of switches and routers from vendors such as Ubiquiti, D-Link, Netgear, Supermicro and TP-Link.

Sustained Operation Across 0–70 °C

The transceiver is rated for continuous operation between 0 and 70 °C, with a storage range extending from -40 to 85 °C. Digital Diagnostic Monitoring reports real-time status to SNMP management tools, allowing administrators to track performance during extended deployments. Hot-swappable insertion supports maintenance without network downtime.

Verify MSA Acceptance and LC Single-Mode Cabling

Before ordering, confirm that the target switch or router accepts uncoded MSA modules and provides an LC duplex port for single-mode fiber. The link budget assumes standard single-mode cable; ensure the planned run does not exceed the rated 10 km distance. No additional accessories are included beyond the transceiver itself.

Questions about this item

How much heat does the SFP1000LXST generate when running continuously at 0–70 °C?

The module is rated for continuous operation from 0 to 70 °C (32 to 158 °F) with 5–95 % humidity, so it stays within spec in standard rack environments without additional cooling.

Which switch or router port is required to accept this LC duplex transceiver?

It needs an MSA-compliant SFP cage that accepts uncoded modules; compatible brands include Ubiquiti, D-Link, Netgear, Supermicro, TP-Link and others that support 1000BASE-LX.

Will the 1310 nm single-mode link work alongside older 1000BASE-SX multimode gear on the same network?

Yes, the 1 Gbps 1000BASE-LX standard interoperates with other IEEE 802.3z devices, so you can mix single-mode and multimode segments as long as each link stays within its rated distance.
