The Transition Networks J/RS232-CF-01(SC)-NA is a stand-alone RS-232-to-fiber media converter with a DB-9 serial port and duplex SC fiber connection, suited to network or facilities teams extending compatible serial devices over multimode fiber.

Recommended For

  • Campus or business network integrators extending a point-to-point RS-232 connection from a remote terminal to a host beyond the typical copper serial-cable run, using multimode SC fiber.
  • Teams connecting RS-232 devices such as POS equipment, security scanners, remote terminals, or building access and alarm systems to a host over a fiber link.
  • Technicians working with a DCE serial endpoint that needs a female DB-9 connection, provided the other end of the link and serial cabling are compatible.
  • Installers moving low-speed asynchronous RS-232 data over an existing multimode SC fiber run, within the product’s stated 2 km fiber reach and up-to-120 Kbps data rate.
