Cb-Re And Rcb Interface Cable And Wire Specifications For Mx Series Routers - Juniper MX2010 Hardware Manual

When chromatic dispersion is at the maximum allowed, its effect can be considered as a power penalty in
the power budget. The optical power budget must allow for the sum of component attenuation, power
penalties (including those from dispersion), and a safety margin for unexpected losses.
CB-RE and RCB Interface Cable and Wire Specifications for MX Series
Routers
Table 47 on page 155 lists the specifications for the cables that connect to management ports and the wires
that connect to the alarm relay contacts.
NOTE: In routers where the Routing Engine (RE) and Control Board (CB) are integrated into a
single board, a CB-RE is known as Routing and Control Board (RCB). The RCB is a single FRU
that provides RE and CB functionality.
