Product Description
The EM316E3 modules of the Fiber Driver Family are Fiber Modems designed to
convert a E3 interface into high-speed fiber optic interface, thus enabling the extension of
the E3 maximum spanning distance up to fiber optic distance limit. These units convert
the electrical signals from a coax cable to optical signals and transmit them over distances
of up to 7km on multimode fiber, or distances of up to 100km on singlemode fiber. The
EM316E3 supports ITU-T G.703, ITU-T G.823, and HDB3 line codes.
The EM316E3SF Fiber Driver's single fiber modules use unique technology that provides
the ability to combine TX and RX signals onto a single fiber strand. This effectively
doubles the available fiber in a network and eliminates the need for additional fiber
connections. An identical EM316E3SF unit is required on the other end, using either
standard APC (Angled PC) patch cords finish or a 3M VAR APC finish. The standard
APC finish provides a <60dB back reflection, whereas the 3M VAR exceeds –70dB.
Both APC finishes are polished to an 8
o angle and minimize back reflection by forcing
the reflected rays into the cladding.
The Fiber Driver family provides conversion solutions with greater distances and better
manageability than any other products on the market. Multimode to Single Mode fiber
conversion modules offers link distances from 0 km to 100 km.
