SG4000 Installation and Operation Manual
3
Assemble the splice enclosure following the instructions furnished with the enclosure.
CAUTION!
It is important that the connections at the headend be duplicated. If they are different from the above
recommendations, follow the scheme used for the headend connections.
4 Complete the splicing and installation of the splice enclosure.
5 Suspend the extra cable from the messenger using locally accepted methods.
Commonly used methods include suspending it from the messenger along its entire length
and/or fashioning a figure eight coil and suspending it from the messenger.
If the housing is to be installed at a later time, protect the end of the service cable with the
compression fitting and the fiber connectors from dirt and moisture.
DANGER!
To avoid possible injury to personnel or damage to the equipment, remove 60/90 volt AC power from the system
before you install the node.
Fiber Cables
To install fiber cables in the lid:
1 Remove the protective port plug from the side of the housing lid and carefully pass the
connector ends of the fiber service cable through this port.
It is necessary to insert one connector at a time. Be careful not to bend the fiber any more
than is necessary.
2 Thread the compression fitting into the port.
The compression nut and rubber grommet must be sufficiently loose to enable the fitting to
be turned without turning the fiber cable at the same time.
3 Torque the main body of the fitting to 60 to 72 in-lbs (5 to 6 ft-lbs).
4 Carefully dress the excess fiber into the fiber spool tray.
5 Wrap the fiber around the spooling cylinder one to two times depending on the length of the
fiber.
The diameter of the spool tray is matched to the bend radius of the fiber. Also, ensure that
the fiber is routed under the retaining flanges and through the pegs of the fiber tray for
proper routing to the optics modules.
The SG4000 station can accommodate up to two fiber management trays. When only one
tray is required, you may position the tray on the side of the node that best facilitates fiber
routing. To remove the fiber tray, carefully depress the plastic locking tab on the right side
of the tray and disengage it from the metal bracket.
