2.9.1 Line equipment for fiber-optic cables
If the 2 Mbit/s signals are to be routed via fiber-optic cables, Port LE2 OPT
U modules must be provided.
The Port LE2 OPT U module offers two electrical equipment interfaces and
two optical card slots which can be flexibly equipped with 1F and 2F
modules.
Module 1F
The 1F module (62.7026.580.00-A001 and 62.7026.580.00-A002) provides
one 2 Mbit/s interface. Transmission in the Tx and Rx direction takes place
via one single fiber using the wavelength-division multiplex procedure.
Module 2F
The 2F module (62.7026.570.00-A001 und 62.7026.540.00-A001) provides
one 2 Mbit/s interface. With this module, transmission in the Tx and Rx
direction takes place via separate fibers.
The laser used on the modules fulfills Laser Class 1 conditions both
in operation and in case of a fault.
