The FOCF is a transparent media converter from short range Multi-Mode to long range Single Mode optical interfaces for Fast-Ethernet or Gigabit-Ethernet networks.

The FOCF is used to interconnect two Ethernet devices with different optical interfaces. It is a very economical solution for connecting over a long distance optical link to a high end equipment with a multimode Gigabit Ethernet interface.


The FOCF provides the ability to extend optical LAN over long distances.

With a full duplex 200 Mbps or 2,000 Mbs bandwidth, the FOCF is a pure media converter transparent to VLAN and up to 9,216 bytes Jumbo frames which makes it a nice interconnection solution for network server applications. The FOCF embeds a temperature control systems that monitors the high power optical transceivers and can generate alarms.

The FOCF is powered from an external 110/230 Vac to 12 Vdc adapter or an optional 48 Vdc to 12V dc converter.

The FOCF fiber / fiber range of converters includes:

FOCF-FX-MM-GLX-SMvv: 100FX 2km / 1310 nm multimode to 100FX single-mode with 25 / 40 / 60 / 100 km distance,

FOCF-GSX-GLX-SMvv: 1000SX multimode 500m to 1000LX single-mode 10 / 30 / 60 km distance.


DCDC-FOCI-48V: 48 Vdc to 12 Vdc power converter for FOCI, FOCF

DIN-FOC: DIN rail mounting lit for FOC , FOCF or FOCI.
