TX Matrix Cables Description

 

Fiber-Optic Array Cables

The fiber-optic array cables connect the switching planes of the T640 routers to the TX Matrix router by connecting the T640-SIBs to the TX-SIBs. Cable lengths from 3 m to 100 m are supported to accommodate both centralized and distributed TX Matrix configurations. The fiber-optic array connector is shown in Figure 1.

You can order cable lengths of 4 m, 5 m, 6 m, and 12 m from Juniper Networks. If you require cables longer than 12 m, you must order them directly from the manufacturer. Contact your Juniper Networks representative for more information.

Note

A fiber-optic array connector is attached to each end of a fiber-optic array cable and plugs into a fiber-optic array adapter on a TX-SIB and a T640-SIB.

Ethernet Cables

The UTP Category 5 Ethernet cables, which use straight-through wiring and RJ-45 connectors on each end, are used for controlling the T640 routers and for out-of-band management of the routing matrix. Controlling the T640 routers requires connections from the two TX-CIPs in the TX Matrix router to the T-CBs in the T640 routers. Out-of-band management requires connections from the TX-CIPs to external management devices.

These cables can be up to 100 m long.

DB-9 Serial Cables

The DB-9 serial cables are used to connect a system console or laptop computer to the TX-CIPs for local management of the routing matrix.
