The NFG Gigabit Ethernet media converter series is designed to convert 1000Base-T signal to/from 1000Base-LX signal. It is used to extend the connection distance between two Copper Gigabit Ethernet devices via fiber cable transparently with no performance degradation. The series supports a single mode fiber up to 120 km. They are also available in dual fiber or single-fiber (Bi-Di) options. It can be used as a standalone device or mounted with a standard 19" chassis.

   The NF Fast Ethernet media converter series is designed to convert 10/100Base-TX signal to/from 100Base-FX signal. The series supports a single mode fiber up to 200 km with SC connector types. They are also available in dual fiber or single-fiber (Bi-Di) options. It can be used as a standalone device or mounted with a standard 19" chassis.

• Control of integrity of a copper and optical line with:
  LLCF (Link Loss Carry Forward) and LLR (Link Loss Return for fiber port)

LLCF (Link Loss Carry Forward)
    When LLCF is enabled, the ports do not transmit a link signal until they receive a link signal from the opposite port. Link loss is "carried forward" to the managed switch or hub that is sending the link. LLCF can be used for either copper or fiber ports.
LLR (Link Loss Return) is used to detect link problems only on the fiber port
    When LLR is enabled (SW2), the fiber port's transmitter shuts down if its receiver fails to detect a valid receive link. If one of the optical conductors is bad, the converter with LLR enabled will return a no link condition to its link partner. Both can immediately alert administrators to problems with the link media, and provide an efficient solution for network monitoring.
