The StarTech.com ET91000SM10 is a Gigabit Ethernet copper-to-fiber media converter for network teams extending a GbE connection up to 10 km over single-mode LC fiber.
Recommended For
- IT teams connecting a Gigabit Ethernet device in one building to a network in another, when the fiber route is within 10 km and uses compatible single-mode LC fiber.
- Business, education, or government network installers extending a copper Ethernet connection over fiber where reducing exposure to electromagnetic interference is important.
- Warehouse or factory IT staff linking a Gigabit Ethernet device across a long fiber run; the converter has a steel enclosure and supports standalone use.
- Network administrators bridging an RJ45 Gigabit device to an existing fiber network, or adding a fiber link where Wi-Fi is unreliable or unavailable.
Real-World Use Scenarios
- To link a detached building to a campus or office network, connect a copper Ethernet device to existing single-mode fiber; the remote side needs compatible fiber networking, such as a fiber-equipped switch or a matching converter, to provide a Gigabit link without a long copper run.
- When a copper-only switch or network device must connect to a fiber backbone, use the converter at the copper endpoint to bridge the connection; this can extend the existing equipment’s reach without replacing it with a fiber-port device.
- In a factory or warehouse where electrical interference makes a copper run less suitable, carry the network connection over fiber between the locations; fiber is less susceptible to electromagnetic interference, while the converter provides a copper Ethernet connection at its endpoint.
- To reach a remote office or equipment area where Wi-Fi is unavailable or unreliable, extend a wired network connection over existing single-mode fiber; the far end still needs compatible fiber equipment and a local power source.
- For a remote surveillance or other network segment, use the converter to carry Ethernet traffic over a long fiber link to network equipment at the remote location; cameras or other devices need their own power, since this converter does not provide PoE.
