The StarTech MCM110ST2 is a 10/100 Mbps Ethernet-to-multimode-fiber media converter with an ST duplex fiber port, an RJ-45 port, and support for fiber links up to 2 km. It suits network administrators extending compatible Ethernet networks over multimode fiber.

Recommended For

  • Network or facilities teams extending a 10/100 Ethernet connection between buildings or across a large site where compatible ST-terminated multimode fiber is already installed.
  • IT teams connecting remote 10/100 equipment—such as traffic or monitoring systems—to a central network over a multimode fiber run.
  • Organizations maintaining legacy Fast Ethernet equipment that needs a copper-to-100Base-FX fiber connection rather than a Gigabit upgrade.
  • Teams routing network links through locations where electrical interference is a concern and compatible multimode fiber is available.

Real-World Use Scenarios

  • To connect a copper-only switch or Ethernet device to an existing multimode fiber run, install the converter at the copper endpoint and use a compatible fiber connection at the other end; network traffic can cross the fiber without replacing the device.
  • For a link between buildings or distant areas of a site, use the converter to carry a 10/100 Ethernet connection over compatible multimode ST fiber; this can extend a network beyond a typical copper run, up to the product’s stated 2 km limit.
  • When reusing older 10/100 Ethernet equipment on a fiber-connected network, the converter can bridge its RJ-45 connection to multimode fiber, avoiding an upgrade solely to add a fiber port.
  • Where a network cable route passes through an electrically noisy area, carrying the link over fiber can avoid relying on a long copper Ethernet run; the copper device still connects locally by RJ-45.
  • In a network that carries tagged VLAN traffic, the converter can pass 802.1Q tags transparently, helping extend an existing VLAN-connected link over fiber without changing the connected Ethernet device.
