Mx10003 Management And Console Port Specifications And Pinouts; Connector Pinouts For Mx Series Cb-Re Or Rcb Auxillary And Console Ports - Juniper MX10003 Hardware Manual

For multimode transmission, modal dispersion, rather than chromatic dispersion or attenuation, usually
limits the maximum bit rate and link length. For single-mode transmission, modal dispersion is not a factor.
However, at higher bit rates and over longer distances, chromatic dispersion rather than modal dispersion
limits maximum link length.
An efficient optical data link must have enough light to exceed the minimum power that the receiver
requires to operate within its specifications. In addition, the total dispersion must be less than the limits
specified for the type of link in Telcordia Technologies document GR-253-CORE (Section 4.3) and
International Telecommunications Union (ITU) document G.957.
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.

Ports
The ports–labeled—AUX and CONSOLE—on the Control Board and Routing Engine (CB-RE) or the Routing
and Control Board (RCB) are asynchronous serial interfaces that accept an RJ-45 connector. The ports
connect the Routing Engine to an auxiliary or console management device.
the RJ-45 connector pinout.
NOTE: In routers where the Routing Engine 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 Routing Engine and CB functionality.
