Product Description

The EM316T1 and the EM316E1 modules of the Fiber Driver Family are Fiber Modems
designed to extend the distance and transmission reliability of T1 (1.544Mbps) or E1
(2.048Mbps) traffic. These units convert the electrical signals to optical signals and
transmit them over distances of up to 4km on multimode fiber, or distances of up to
100km on singlemode fiber. The EM316T1 and EM316E1 are transparent to the framing
format, and support AMI or B8ZS (T1) and HDB3 (E1) line codes respectively. They
include an internal elastic buffer to remove jitter from transmit data. Six LED indicators
help monitoring and trouble-shooting, and a management agent is incorporated on the
module to enable remote in-band and out-of-band control and management in
conjunction with the Fiber Driver SNMP management card.

The EM316E1/T1 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 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 Singlemode fiber
conversion modules offers link distances from 0 km to 100 km.
