This section describes the various communication cables connected to the line
cards installed in the ATM Switch and how to connect them.
The following types of communication cables are available for the ATM Switch:
Physical Layer Throughput
OC-12/STM-4 622 Mbps
OC-3/STM-1 155 Mbps
OC-3/STM-1 155 Mbps
TAXI 100 Mbps
OC-3/STM-1 155 Mbps
J2 6.3 Mbps
DS3 45 Mbps
E3 34 Mbps
Optical Cables
There are two types of optical cables: single-mode optical fiber cables and multi-
mode optical fiber cables. The single-mode optical fiber cables are used for OC-
12c and OC-3c/STM1-SMF and the multi-mode optical fiber cables for OC-3c/
STM-1-MMF and TAXI.
The single-mode optical fiber cables used for the ATM Switch have core/clad
diameters of 9.5/125 µm and the multi-mode optical fiber cables of 50/125 µm or
62.5/125 µm.
The optical cables are connected with SC connectors. When connecting the cables,
be careful of the transmission-reception direction. Be sure to connect one end to the
transmission side and the other to the reception side.
Optical fiber cable can transmit cells over a distance so as long as the optical
reception level shown in the following table is satisfied.
