Direct Connections with Cable Storage Drawers

Optical components on the Cisco ONS 15540 ESPx can be cabled together in two
different ways:
Direct connections with an MTP cable storage drawer
•
•
With cross connect drawers
MTP cables directly connect line card motherboards to optical mux/demux
motherboards. One end of each MTP cable connector plugs into a line card
motherboard MTP adapter. The other end of the cable plugs into a mux/demux
motherboard MTP adapter.
When using the cross connect drawers, the line card motherboards and the
mux/demux modules are separately connected to the cross connect panel. One end
of a cable plugs into a line card motherboard or a mux/demux motherboard. The
connections to the cross connect drawers are made using breakout cables. The
cables break out to single fiber cables, which then plug into one end of a high
density (octal-MU) adapter. The connections between line card motherboards and
mux/demux modules are then made using single fiber cables (terminated in MU
connectors at both ends). One end of each of these single fiber cables plugs into
an adapter connected to a line card motherboard and the other end into another
adapter connected to a mux/demux module.
Final connection between the line card motherboard and the mux/demux module
is made using up to sixteen single fiber MU-to-MU cables. The MU connector on
one end of the cable plugs into an octal-MU adapter connected to the line card
motherboard. The other end of the connector plugs into an adapter connected to
the mux/demux module.
The cable storage drawer can accommodate attenuators that are available from
optical component distributors.
When you make direct connections in the Cisco ONS 15540 ESPx, you connect
the line card motherboard MTP connections directly to the MTP connections on
the mux/demux modules or mux/demux motherboards. This connection requires
just one MTP cable storage drawer.
