Taking inventory
After the equipment has been unpacked and visually inspected, verify that
all the equipment is at the site before the installation begins. Equipment
received must be checked against the shipping documents. Any shortages
must be noted and reported to the sales representative.
Installing the fiber-optic link
If the fiber-optic link already exists, check its fiber-optic link characteristics
and the end-to-end loss to determine if the link can support a Fiber
Remote Multi-IPE Interface units and, if it can, at what distance between
the local system and the Remote IPE.
Consult the Nortel distributor to learn how to verify that the existing
fiber-optic link is suitable for the Fiber Remote IPE application and what
equipment to use to do so.
To connect the fiber-optic link to the Fiber Remote Multi-IPE Interface ST
optical connectors at the local site and the Remote IPE site, the link fibers
must be terminated with ST-type optical connectors.

Visually inspect the equipment for obvious faults or damage. Any
damaged component must be reported to the sales representative and
the carrier who delivered the equipment.
Do not bend and twist the fiber-optic cables excessively. Make sure
that the cable is not bent beyond the specified minimum-bending
radius of 1.4 inches (3.5 cm) when handled or installed.
CAUTION
If changing a fiber-optic system to the Fiber Remote Multi-IPE
Interface, make sure that the fiber-optic link connectors are
changed to the appropriate ST-type. The ST-type optical
connector must correspond to the type of fibers used in the
fiber-optic link (that is, single-mode or multi-mode). A fiber-optic
adapter cable can also be used to adapt the existing connector
type to the ST- type if the total link attenuation, including the
adapter, does not exceed the maximum acceptable link loss.
Keep the optical connectors absolutely clean. Use pure
isopropyl alcohol-treated lint-free wipes to clean the ferrule part
of the optical connector and an aerosol duster to blow out dust
particles from the adapter part of the optical connector.
Make sure that the ferrules in the optical connectors are
properly installed and aligned in their respective adapters. This
is particularly critical for the single-mode fibers where tolerances
are tighter.
