S.I.Tech 2062 is designed to be used as a repeater on fiber optic networks. This repeater extends the distance of fiber optic Arcnet, Ethernet, Token Ring, TTL or T1/E1 links up to 10 Km. This repeater can be configured to convert from multimode to single mode fiber. The 2062 can also be used to convert from one size of fiber to another, e.g. 50/125 to 62.5/125 micron.
