10 Chapter 1 Traverse Equipment Specifications
Power Cabling
Redundant central office battery and battery return is connected to the PDAP. The
PDAP-2S distributes battery and battery return to up to two Traverse shelves and up to
ten pieces of auxiliary equipment in a rack. The PDAP-4S distributes battery and
battery return to up to four Traverse shelves and up to five pieces of auxiliary
equipment in a rack.
Both the PDAP-2S and PDAP-4S have two DC power inputs (Battery ‘A’ and
Battery ‘B’). Each of these inputs is capable of supplying power to the Traverse system
during central office maintenance operations. The recommended gauge wire for power
cabling is #8 AWG (a 9 mm
2
cable).
See the Traverse Cabling Guide, Chapter 10—“Cable Management Specifications” for
detailed power cabling instructions.
Fiber
Connectors
and Cabling
MPX Connectors
Each optical card in a Traverse system can terminate up to 48 fibers, or support up to 24
optical interfaces. It has female duplex housings to accept the MPX multifiber array
connectors located on the optical cards. All MPX connectors have a precise alignment
mechanism to provide quick and easy installation. The optical backplane supports
single-mode and multi-mode fiber optic cable.
A fiber optic patch panel may be used to provide access and standard connectors (SC,
FC, ST, LC, or D4) for termination of fiber optic cables from the optical distribution
frame (ODF) and from the Traverse fiber optic backplane. Fiber optic cable with an
MPX female connector on one end must be used to make the connection at the Traverse
fiber optic backplane. An SC connector on the other end of the fiber optic cable is the
recommended option. Fiber optic cable with fan out for termination to single fiber
connectors (SC, FC, ST, LC, or D4) is another option.
For Ethernet Combo cards, Force10 provides an optional snap-in faceplate patch panel
for termination of fiber optic cables (4-port SC duplex adapter card for SM/MM) and
Category 5 cables (RJ-45 modular jack) for flexibility and better identification of pairs
terminated at the intermediate patch panel.
SFP Connector Module
The Traverse shelf also provides a small form-factor pluggable (SFP) connector
module (SCM) to support high-density and easy-operation fiber connection for the
10-port Gigabit Ethernet (GbE-10) module.
The GbE-10 module must be ordered with a 10-port SFP connector module (SCM).
