Connectors & Cables
The converter provides one multimode (MM) fiber port
and one single mode (SM) fiber port as shown below:
The multimode fiber port is used for a duplex multimode
fiber cable connection and single mode fiber port is used
for a duplex single mode fiber cable connection.
Both ports are compliant to IEEE 802.3u 100BASE-FX
standard and can convert multimode optic signal to single
mode optic signal up to bandwidth 200Mbps transpar-
ently with a minimal delay time.
The wavelength used is 1300nm for both ports. The
recommended MM (Multimode fiber) cable is
62.5/125

General Description
The KC-220FF Fast Ethernet media converter series are de-
signed to convert a 100BASE-FX multimode fiber signal to
single mode fiber signal. It is used to extend the connection
distance between two Fast Ethernet fiber optic devices via
single mode fiber cable transparently with no performance
degradation. The converter series provide different types of
fiber connectors such as ST, SC, and MT-RJ for MM (multi-
mode) or SM (single mode) fiber cables.
